From a recent article by Coretecs management , Note SiH4 is Monosilane
CoretecHexaSilane (CHS ) Is going to be i believe a BIG TIME SILICON PRECURSOR !!
Turning Potential to Reality
The development of silicon anodes for lithium ion batteries has also been hampered by commercially scalable methods to produce nanostructured materials with well-defined size and morphology, with characteristic sizes below 150 nm. Traditional top-down methods, including ball milling, are inexpensive and yield silicon materials with high degrees of agglomeration, relatively large particle sizes, and poorly defined morphologies and surfaces. Metal assisted chemical etching is an alternative method that has been explored to synthesize silicon nanomaterials. Control over the morphology, etching direction, mass transfer issues, and the requirement for highly toxic reagents such as hydrofluoric acid limit the commercialization of that method. Meanwhile, bottom-up methods such as chemical vapor deposition (CVD) methods have also been the subject of intense exploration. CVD-based synthesis yields well-defined particle sizes and a diverse array of nanostructured architectures including nanoparticles (NPs), nanowires (NWs), and thin films. A major hindrance to using CVD methods has been high capital cost, low yields, and the use of hazardous and pyrophoric gaseous silicon feedstocks such as silane, SiH4.
The solution may lie in a silicon-carbon hybrid anode, made with nanostructures that store more lithium ions, while reducing the potential for damage as the silicon expands. These hybrid nanostructures include silicon-coated carbon nanotubes, core-shell nanostructures, and carbon coated silicon nanowires grown by electrospinning or by the vapor-liquid-process. Cyclohexasilane, CHS, enables commercially viable approaches to manufacture these nanostructures due to its ability to be readily functionalized, more ideal handling conditions, and more favorable reaction conditions. All of these merits could result in single-step processing and roll-to-roll manufacturing. This “drop-in” replacement to existing manufacturing processes would offer a means to reduce costs and avoid using CVD methods that have high capital costs.
The figure below highlights the merits of this approach, illustrating that with relatively low silicon incorporation into the anode structure, an increase in the energy density by roughly 3x is readily achieved, while maintaining good cycle life.2
Moreover, the resulting silicon nanostructured morphology can be readily tailored to deliver nanofibers or nanoparticles with a desired size and conductive carbon additive. Silicon thin films are also a possibility, and we envision deposition mechanisms that alleviate some of the delamination issues that have plagued previous efforts.
What’s Next?
The lithium-ion battery market is projected to grow at a CAGR of 13.7% between 2017 and 2022, to a value of USD 67.7 billion. As consumer demand grows for battery-enabled technology, manufacturers are investing in battery research and development, with the goal of speeding the advancement of energy density in lithium-ion batteries.
Silicon-based anodes figure to capture an increasing share of that market, and R&D efforts in that area among major global players and startups is increasing considerably, primarily from battery manufacturers, auto makers and more. As energy density improves, we can look forward to product advancements across the technology sector, and the introduction of products not yet imagined.
From a previous Coretec news release on CHS and the anticipation of replacing Silane Trichlorosilane
Coretec's underlying technology is based on the efficient production of a high value liquid silicon precursor, cyclohexasilane ("CHS"). A key advantage of CHS is that it is a liquid at room temperature and does not convert to a gas until heated above 400°F. This compares to materials commonly used for manufacturing silicon-based semiconductors and solar cells (silane and trichlorosilane) that have much lower boiling points (-170F and 90°F, respectively) which leads to higher cost handling and shipping. Another key advantage of CHS, when compared to materials commonly used for manufacturing silicon-based semiconductors and solar cells, is that the production rate of the silicon forming step can be increased by a factor of six, leading to additional cost savings. Based on these competitive advantages and inquiries from potential users, Coretec anticipates that CHS will first be used as an alternative to silane or trichlorosilane in silicon-based semiconductor and solar cell manufacturing.
So many uses for CHS , CoretecHexaSilane ,the best silicon precursor out there , the S emi-conductor market for 2017 about 417,000 billion dollars !!! NICE !!!
Michael Kraft from a recent blog !!
As we have mentioned, we have continued to host discussions with several Si anode customers in consumer electronics and EV and they agree that based on several unique and novel methods to impart Si into the graphite anode, the path to higher energy density is silicon. To that effect, we are confident CHS (Si6H12) is the superior silicon precursor and can form Si nanomaterials and thin films at lower energy/temperatures and with higher purity. CHS represents a far better precursor choice over ANY other material. New materials development requires patience to commercialize, but knowing that other methods are failing, we firmly believe the future for battery design is high energy density batteries with Silicon anodes that have replaced conventional precursors with CHS.
Coretec HexaSilane ,i believe ,will replace Trichlorosilane ( HSiCl3)and is a FAR better silicon precursor !! The Coretec Group holds all the cards !!! SiH4 , Monosilane ,i believe ,will be replaced in time as well !!! as well as other silicon precursors .BILLION DOLLAR CHEMICALS ! This is not hard to understand get ready !! Do your DD !!

Introduction
Silicon chlorides are some of the cornerstone chemicals of the Information Age. Trichlorosilane (HSiCl3) is an intermediate compound used to produce extremely pure silicon, from which computer chips, the "brains" of electronic devices and high-tech toys, are manufactured. The famous high-tech industrial area of California, Silicon Valley, was named for the chemical element that has revolutionized the way we communicate and play. And chlorine has played an essential role in the high-tech revolution.
The Secret is Silicon and Nanoengineering
Great article showing that Coretec believes CHS is THE #1 PRECURSOR !!!
Aug 24, 2018

Billions (with a B!) of dollars are spent annually improving battery density to improve weight per kilowatt hour (kWh) and cost. The need spans consumer electronics as well as many industrial applications, many of which are high growth. A great example is the electric vehicle (EV) sector, one that many believe is the future of the automotive industry. Coretec also believes EVs are the car of the future, and more specifically that Si anode batteries are the future of EVs.

Great things ahead for CHS as it can be converted to crystalline silicon and as we can see from the article below 90% of the shipments of solar technology products use crystalline silicon , therefore Coretec new silicon precursor Si6H12 which Coretec says is far better than any precursor today could end up in solar tech through crystalline silicon and be a dominant player !!! Huge !!!
Coretec’s lead product candidate is cyclohexasilane or Si6H12 (CHS), a liquid at room temperatures (and up to 175 °F), which when exposed to heat or UV irradiation, converts to amorphous silicon and, if desired, crystalline silicon. The Coretec Group believes further development and eventual commercialization of the product will result in improved performance, reduced cost, simplified manufacturing, and safer handling when compared to the more traditionally used mono-silane.
From a Coretec article on CHS !!!
Solar is a growing sector due to the increasing stringency of renewable energy demands, how is silicon currently being used in this sector?
Crystalline silicon remains the dominant solar technology with over 90% of the shipments. Crystalline solar cells are commonly produced from rigid silicon wafers sliced from large boules of silicon. After significant growth of utility-based systems, a major trend underway is a return to distributed power generation at the point of use. While rigid silicon wafers are suitable for many rooftop installations, solar capability that can more easily and affordably be applied to a broad range of building materials is desired. We believe we can take advantage of this trend by providing an ink-jet printable liquid CHS that can be converted into poly-silicon or micro-crystalline silicon cells.
Coretec is in a great position since they hold all the cards which they do having the #1 Si Atom out there . They are on the verge of great things !!! What a position to be in for Coretecs management and their customers I'm sure are extremely excited about getting this new material into their technologies as fast as possible !! THE BEST IS YET TO COME !!!
THIS "HIGH GROWTH PRINTABLE ELECTRONICS MARKET FOR SILICON BASED TECHNOLOGY" ARTICLE BY CORETEC SHOWS JUST ANOTHER GREAT APPLICATION FOR CORETECS NEW MATERIALS !!!
Printable electronics fuses two major industries - electronics and printing - resulting in one rapidly growing sector. Applications of printable electronics visible to consumers exist in the form of radio- frequency identification (RFID) tags which are commonly used to track inventory (e.g. DVD cases or apparel), cars (e.g. EZPass), baggage, and other materials. These devices can hold an abundant amount of information that can be quickly scanned and digested, a key reason for widespread adoption that has created a large market for the technology. Printable electronics are produced by printing inks having various electronic material properties onto low temperature plastic or paper films using low cost roll-to-roll manufacturing processes. A challenge has been developing an ink that when printed exhibits the unique electronic material properties of silicon. CHS has this unique capability. CHS is a liquid at room temperature, which simplifies storage, transportation, and handling while improving safety. Derivatives of CHS can be produced that incorporate Boron and Phosphorous, required to make electronics, and further improves safety while simplifying processing. Once printed, CHS can be converted into silicon at low temperatures. The electronic properties of the silicon produced with CHS were found to be superior to that of competing printable inks. "Our acquisition of Coretec and its portfolio of silicon technologies was driven by the opportunity for commercialization in several rapidly growing markets, notably printable electronics," said Doug Freitag,."Security and supply chain needs within retail, manufacturing, and other applications have created significant demand for printable electronics, resulting in what we believe is significant market potential for our technology. As the industry continues to evolve, we believe the continued development of our technology portfolio ultimately positions us to generate future revenue. A recent market report published by IDTechEx forecasts the printable electronics market to reach $69 billion globally by 2026, led by technologies already in use or under consideration for RFID tags, security/monitoring, data storage, display and visual effects, and toys. The report also stateshat the largest current opportunity exists for organic light-emitting diode (OLED) displays, sensors, and conductors, all three of which are already billion dollar industries.:
THIS IS A GREAT ARTICLE HIGH-LIGHTING CORETECS NEW MATERIALS THAT WILL BE VERY SUCCESSFULLY MARKETED IN SEVERAL BILLION DOLLAR MARKETS !!! GREAT STUFF !!!
In what industries are you seeing growth in use of silicon and where do you see the greatest potential for this material?
Silicon has such a ubiquitous influence in so many industries it provides us with an overwhelming number of potential opportunities. Markets where we see the greatest near term potential include those where expensive and potentially hazardous silicon precursor materials are currently used to form silicon films, e.g., solar, displays, imaging, photonics, medical diagnostics, and semiconductors. Emerging markets where we see potential include energy storage, solid state lighting, authentication and printable electronics. These opportunities go beyond the gaseous deposition of silicon films, and benefit from our ability to convert CHS into nanoparticles and nanowires or directly from a liquid into a silicon film.
What are the benefits of high yield silicon gas compared to high yield silicon liquid and what applications are each suited for?
[/b]CHS is a more benign liquid phase alternative to gaseous silane (SiH4) and corrosive trichlorosilane (HSiCl3), tetrachloride (SiCl4), or dichlorosilane (SiH2Cl2) commonly used for manufacturing silicon devices which will lead to simplified storage, transportation and use, all at reduced cost. When used for gaseous deposition, CHS provides for higher deposition rates at lower temperatures when compared to alternatives, leading to increased capacity at reduced cost. CHS is a more affordable alternative to commercially available cyclopentasilane (Si5H10) commonly used in the emerging field of printable electronics.
What demands are you seeing in the energy storage sector where silicon usage is relevant?
A key attribute of silicon in lithium ion batteries (LIB) is the higher capacity that Si can offer which leads to greater electric vehicle driving range or longer operating consumer electronics. A remaining challenge however is the limited lifetime of LIB when crystalline Si breaks down during their repeated charge-discharge cycle and some parts become electrically isolated and no longer contribute to capacity.
With energy storage using lithium-ion batteries, how are silicon developments enhancing battery life-span?
A number of methods are being considered to overcome this limitation including blending nanowires grown by gas deposition processes with carbon. While good performance has been reported, the cost of this approach remains high. We believe the higher deposition rate of CHS and its derivatives will lead to lower cost while improving production capacity. We have also demonstrated the ability to electrospin liquid CHS into silicon nanowires that when blended with carbon lead to performance comparable to that achieved by CVD grown silicon nanowires but at reduced cost and simplified scaling.
Solar is a growing sector due to the increasing stringency of renewable energy demands, how is silicon currently being used in this sector?
Crystalline silicon remains the dominant solar technology with over 90% of the shipments. Crystalline solar cells are commonly produced from rigid silicon wafers sliced from large boules of silicon. After significant growth of utility-based systems, a major trend underway is a return to distributed power generation at the point of use. While rigid silicon wafers are suitable for many rooftop installations, solar capability that can more easily and affordably be applied to a broad range of building materials is desired. We believe we can take advantage of this trend by providing an ink-jet printable liquid CHS that can be converted into poly-silicon or micro-crystalline silicon cells.
What enhancements are being made to make silicon wafer development more efficient and effective?
The cost of silicon wafers remains a major contributor to the overall cost of solar modules.
One approach to decreasing the cost of crystalline silicon solar cells is to reduce their thickness. By 2020 it is forecast that silicon wafers used in solar will only be 100 microns thick. Multiple approaches continue to be explored including advances in wafer slicing, ribbon growth and gas phase deposition. We believe we can enhance the rate of gas phase deposition methods being considered by using CHS, which ultimately leads to lower cost.
Do you have products or processes in the pipeline? When do you expect to come to market?
The transition from laboratory-scale production of cyclohexasilane to pilot-scale production is expected to occur within 12 months. The first product to be launched will be liquid cyclohexasilane (CHS). Based on market inquires we anticipate the first product will be used as an alternate to silane or trichlorosilane in silicon based semiconductor and solar cell manufacturing processes. Time to market is anticipated to be 1-2 years. We believe this first product will also be considered as an alternate to silicon particles, silicon nanowires, and silicon particle filled inks by the emerging printable electronics and LIB Si-anode industries. Time to market is anticipated to be 3-5 years. The purity of the first product has yet to be determined and will be based on the feedback of early adopters. We anticipate the first product to be released in the US market followed by Europe, Asia, and the UK.

Great day yesterday for trading , CRTG cheap at these prices !!! Great anticipation building for Coretec shareholders as I believe it wont be long Coretec announces their new Major Chemical Manufacturer Partnership name and terms of that agreement which they stated they would do in a previous update !!!! The best is yet to come gets better everyday for sure as Coretecs management is building a very successful company that will be highly successful and generate great revenue through the sale of its new materials Si6H12 that has applications in many different billion dollar markets . This is getting extreemly exciting as they have made amazing progress .Last update abut the battery show once again validates Coretec new materials that will replace the conventional Precursors used today in several billion dollar markets !!
RECENT BATTERY SHOW NEWS UPDATE !!!!
The overall theme of The Battery Show was improving battery technology, and a clear example of this was the prevalent discussion for how to use silicon to get the most gain in Power Capacity (Watt Hours). Coretec met with several companies eager to evaluate and leverage CHS’ value in making their own advanced Li Ion batteries. As a logical next step, Coretec will work with them to cement plans to evaluate CHS as a premier Si precursor to improve the performance of their next generation Li Ion battery.
The Technical Conference was also well attended, including Dr. Elgammal’s presentation entitled “Tunable Syntheses of Advanced Silicon Anodes Using Cyclohexasilane,“ which was very well received by attendees. In fact, many of those in the room had immediate follow-up questions for Dr. Elgammal and Michael Kraft. Overall, the experience expanded Coretec’s potential customer base, positioned the technology very well as a premier Si precursor, and identified several strategic partners to help Coretec with R&D as well as distribution and customer service.
Coretec has the #1 silicon precursor available in Si6H12 which is going to be a huge winner in many markets , the next update will be a great one as Coretecs management is accomplishing great things !!!
Tell us about The Coretec Group and its mission.
The Coretec Group’s mission is to commercialize innovations and disruptive technologies in silicon (Si) and 3D visualization, serving advanced technology markets in support of global challenges in energy, electronics, semiconductor, solar, health, environment, and security.
The Coretec Group has really focused on CHS technology? Tell us about CHS Technology.
CHS, or cyclohexasilane (Si6H12), is an excellent Si precursor, many say the best source for the atom Si. The silicon atom has wide ranging chemical characteristics; from semiconductor chips to silicone caulk to Si oxide (glass). We have many critical materials today that owe their material performance to the silicon atom. Coretec is committed to supplying the best Si precursors for next generation advanced materials and systems, primarily focused on technology markets that need a step function in innovation to reach tomorrow’s solutions.
What benefits can this form of CHS bring to alternative energy markets?
CHS is a liquid up to 175F, which means it can enable room temperature liquid silicon precursor processing; thereby reducing processing costs. In some applications, it can enable unique material properties not achievable with other silicon precursors; which means CHS can deliver unique performance characteristics in the customers application. It starts with this: CHS is a ring of six Si atoms, all six Si atoms have two Si bonds, and the other two bonds to each Si atom are hydrogens. The silicon-hydrogen bonds in this molecular structure are weaker compared to conventional Si precursors due to the molecule’s geometry, which means it is easy to remove the hydrogen and all that is left is PURE Si. Moreover, the unique CHS structure enables preferential formation of Si structures compared to traditional materials such as silane, SiH4. A liquid Si precursor at room temperature, with an easier transformation to pure silicon are some of key advantages of CHS with the added bonus of a lower transition temperature to amorphous Si (a-Si) and crystalline Si (c-Si).
This means CHS-derived Si nanoparticles have many advantages over other Si nanoparticles, AND CHS is more easily functionalized (combined with other atoms, like boron) leading to unique chemical compounds that can deliver tailored Si-materials. Better Si nanoparticles and better Si quantum dots (QDots) make better Si anode batteries, better solar cells, better LEDs, better QDots for drug delivery, and many other uses.
Tell us about the cost savings of CHS as related to energy storage.
The Energy Storage Market needs better batteries. Lithium-ion batteries can realize significant improvements in storage capacity by using Si anodes, and CHS can enable that in two ways. First in process ability; CHS can coat carbon nanoparticles as a liquid, making the coating process faster and cheaper. Second, with some unique processing, CHS can readily form Si nanoparticles which can address the issue of expansion and contraction experienced in charging and discharging Si anode lithium-ion batteries. A lithium-ion battery, however, with a Si anode has the potential to achieve a 300% increase in power density (300% more power output in same size/weight battery). We could also reduce battery weight and attain a significant increase in power. Think of an electric car battery half the size but with a 150% increase in power & distance. All other things being equal, that 200-mile EV range just turned into 500 miles.
Another Great week ahead for The Coretec Group its obvious management is working hard and putting together a great new company with the BEST SILICON PRECURSOR AROUD THAT HAS MANY APPLICATIONS INCLUDING LITHIUM- ION BATTERIES , SEMI-CONDUCTOR , SOLAR , LEDS AND PRINTABLE AND FLEXABLE ELECTRONICS TO NAME A FREW .GREAT THINGS AHEAD THE BEST IS YET TO COME !!

FROM A RECENT CEO UPDATE WE CAN SEE Si6H12 IS GOING TO DO GREAT THINGS !!
As we have mentioned, we have continued to host discussions with several Si anode customers in consumer electronics and EV and they agree that based on several unique and novel methods to impart Si into the graphite anode, the path to higher energy density is silicon. To that effect, we are confident CHS (Si6H12) is the superior silicon precursor and can form Si nanomaterials and thin films at lower energy/temperatures and with higher purity. CHS represents a far better precursor choice over ANY other material. New materials development requires patience to commercialize, but knowing that other methods are failing, we firmly believe the future for battery design is high energy density batteries with Silicon anodes that have replaced conventional precursors with CHS.
Coretec will be extremely successful as they move towards Si6H12 being added as the premium Is precursor to different technologies including Lithium ion batteries ; Below research being done for Tesla under the leadership of Jeff Dahn at Dalhousie University in Canada shows Silicon is the future anode material for batteries and Coretec is leading the way !!!!
Fade mechanisms in Li-ion cells with Si-alloy containing negative electrodes
Li-ion batteries are now used in a wide variety of applications. However, energy density (amount of energy stored per unit volume) still needs to be improved. As such Si alloy materials are of interest for their high volumetric capacity (˜3 times that of the widely used graphite material).
Li-ion cells that contain Si-based materials typically show rapid capacity fade (amount of Li exchanged from the positive electrode to the negative electrode during one charge or one discharge). Understanding why this rapid capacity fade occurs is of upmost importance.
In order to understand this fade mechanism cells containing a negative electrodes consisting of a blend of Si alloy and graphite and a positive electrode consisting LiCoO2 were filled with the same electrolyte and cycled for various amount of time and various rates (currents of various amplitudes). The electrolyte used contained 10 wt% fluoroethylene carbonate (FEC), an additive that has been widely reported as extending lifetime of cells containing Si-based negative electrodes.
Figure 1a shows the capacity vs. cycle number of cells cycled at C/2 and 20°C. Figure 1a shows that cells present a steady initial capacity fade during the first 350 cycles followed by a sudden failure. In order to understand this fade, the composition of the electrolyte was analyzed by gas chromatography. Figure 1a shows that the cell that underwent 100 cycles had only 5.3% of the additive FEC left out of the initial 10%. Figure 1a also shows that the cell that was stopped right before sudden failure had only 0.9% of the additive left while the cell that was stopped after failure had none left. This clearly shows that the additive is consumed rapidly and that its presence in the electrolyte is necessary for cells to function relatively well. Once the additive runs out, the cell undergoes sudden failure.
Figure 1b shows the cell capacity vs. cycling time for cells that were cycled at various rates. Figure 1b shows that cells cycled the fastest (C/2) show more fade for a given cycling time than cells cycled more slowly. If cycling time was the only factor dictating early capacity fade, cells would have the same capacity fade for a given cycling time regardless of their cycling rate. This indicates that some of the fade in Si-containing cells has a cycle-number dependence. This can be understood from the fact that Si or Si-alloy expand upon lithiation (charge) from 120% to 280% of their initial volume. This large volume expansion induces cracks in the protective layer at the surface of the particles. This protective layer is made via the degradation of the electrolyte which produces compounds that precipitates at the surface of the particles thus protecting the electrolyte from further degradation. The creation of this protective layer consumes active lithium. Each time this protective layer cracks upon particle expansion, more active lithium is consumed to regenerate this protective layer. The consumption of active lithium is at the origin of the capacity fade.
The design of Si-containing cells with long lifetime then needs electrolyte that reduces the consumption rate of FEC or uses another passivating agent, as well as uses a combination of electrolyte composition and active material design that reduces the amount of cracks in the protective layer generated by the expansion of the Si.
Figure 1 - 200 mAh Si-alloy:graphite/LiCoO2 pouch cells cycled at room temperature and C/2 (a), 200 mAh Si-alloy:graphite/LiCoO2 pouch cells cycled at 40°C and various rates. All cells were filled with an electrolyte containing 10% fluoroethylene carbonate (FEC).
Coretec on the cusp of Great things for sure , they have the #1 silicon precursor , just a matter of time now !!!! CORETEC IS THE #1 NEW MATERIALS COMPANY IN THE WORLD WHEN IT COMES TO SILICON MATERIALS #1 !!!!
Feedback from The Battery Power Show
Sep 24, 2018
The Battery Show in Novi Michigan, the largest battery show in America, was attended by over 8000 industry professionals, and 600 vendors. One clear take-away -- the electric vehicle trend is large and gaining momentum. Countries including France, Norway, Netherlands, Germany, India and others have put in place regulations to ban combustion vehicles, spurring rapid growth.
The overall theme of The Battery Show was improving battery technology, and a clear example of this was the prevalent discussion for how to use silicon to get the most gain in Power Capacity (Watt Hours). Coretec met with several companies eager to evaluate and leverage CHS’ value in making their own advanced Li Ion batteries.

Overall, the experience expanded Coretec’s potential customer base, positioned the technology very well as a premier Si precursor, and identified several strategic partners to help Coretec with R&D as well as distribution and customer service.
The growth of the EV sector as noted above, combined with the extensive growth of electronic mobility, drives huge demand for lithium ion batteries. According to some market reports, the lithium ion battery market will reach $100-140B by 2026-2027 with a 17% CAGR, making it one of the largest and fastest growing markets worldwide.
Billions of dollars are invested annually to improve the current Li Ion battery which has reached 90% of theoretical energy storage capacity. With the largest improvement in energy capacity reached by adding silicon, the potential exists for a 300% improvement.

Parts of the article tell you what you already know – there is an increased global need for better batteries. It is front page news with technology and financial media alike, and likely affects you on a daily basis (check your phone – is your phone battery dead AGAIN?).
Billions (with a B!) of dollars are spent annually improving battery density to improve weight per kilowatt hour (kWh) and cost.

Parts of the article tell you what you already know – there is an increased global need for better batteries. It is front page news with technology and financial media alike, and likely affects you on a daily basis (check your phone – is your phone battery dead AGAIN?).
Billions (with a B!) of dollars are spent annually improving battery density to improve weight per kilowatt hour (kWh) and cost. The need spans consumer electronics as well as many industrial applications, many of which are high growth. A great example is the electric vehicle (EV) sector, one that many believe is the future of the automotive industry. Coretec also believes EVs are the car of the future, and more specifically that Si anode batteries are the future of EVs.
As we have mentioned, we have continued to host discussions with several Si anode customers in consumer electronics and EV and they agree that based on several unique and novel methods to impart Si into the graphite anode, the path to higher energy density is silicon. To that effect, we are confident CHS (Si6H12) is the superior silicon precursor and can form Si nanomaterials and thin films at lower energy/temperatures and with higher purity. CHS represents a far better precursor choice over ANY other material. New materials development requires patience to commercialize, but knowing that other methods are failing, we firmly believe the future for battery design is high energy density batteries with Silicon anodes that have replaced conventional precursors with CHS.

From Coretecs article on CHS really great to see Coretec has the solution to the problem of adding more silicon to the anode of the lithium ion battery so the energy density can be significantly increased in the anode allowing for much longer range EVs !!!
The solution may lie in a silicon-carbon hybrid anode, made with nanostructures that store more lithium ions, while reducing the potential for damage as the silicon expands. These hybrid nanostructures include silicon-coated carbon nanotubes, core-shell nanostructures, and carbon coated silicon nanowires grown by electrospinning or by the vapor-liquid-process. Cyclohexasilane, CHS, enables commercially viable approaches to manufacture these nanostructures due to its ability to be readily functionalized, more ideal handling conditions, and more favorable reaction conditions. All of these merits could result in single-step processing and roll-to-roll manufacturing. This “drop-in” replacement to existing manufacturing processes would offer a means to reduce costs and avoid using CVD methods that have high capital costs.
BIG TIME STUFF !!!
Pegs , Michael Kraft stated in these articles below that they can use their silicon in the anode and with a battery half the size a convention EV battery and take a fully electric car with a 200 mile range and expand that range to 500 miles.He also stated as we can read that CHs is a far better silicon precursor than ANY other material and also that they firmly believe that the future of lithium ion battery design will use CHS to replace conventional precursors used today !! Also we can read here that Coretec has stated that with incorporating only a LOW amount of Coretec silicon in the anode that they can achieve a 3 times the energy density in the battery . Suppose when they add much higher amounts they will get closer to the potential 10 times energy density that no one has come close to.

The figure below highlights the merits of this approach, illustrating that with relatively low silicon incorporation into the anode structure, an increase in the energy density by roughly 3x is readily achieved, while maintaining good cycle life.2
A lithium-ion battery, however, with a Si anode has the potential to achieve a 300% increase in power density (300% more power output in same size/weight battery). We could also reduce battery weight and attain a significant increase in power. Think of an electric car battery half the size but with a 150% increase in power & distance. All other things being equal, that 200-mile EV range just turned into 500 miles.
How is The Coretec Group working to leverage this technology?
We are working with leading energy storage companies to help them take advantage of the CHS material characteristics mentioned above, as well as other innovators in the other markets mentioned that span a number of applications.

From the article written by Michael Kraft and Ramez Egammel recently : Big time stuff !!
Turning Potential to Reality
The development of silicon anodes for lithium ion batteries has also been hampered by commercially scalable methods to produce nanostructured materials with well-defined size and morphology, with characteristic sizes below 150 nm. Traditional top-down methods, including ball milling, are inexpensive and yield silicon materials with high degrees of agglomeration, relatively large particle sizes, and poorly defined morphologies and surfaces. Metal assisted chemical etching is an alternative method that has been explored to synthesize silicon nanomaterials. Control over the morphology, etching direction, mass transfer issues, and the requirement for highly toxic reagents such as hydrofluoric acid limit the commercialization of that method. Meanwhile, bottom-up methods such as chemical vapor deposition (CVD) methods have also been the subject of intense exploration. CVD-based synthesis yields well-defined particle sizes and a diverse array of nanostructured architectures including nanoparticles (NPs), nanowires (NWs), and thin films. A major hindrance to using CVD methods has been high capital cost, low yields, and the use of hazardous and pyrophoric gaseous silicon feedstocks such as silane, SiH4.
The solution may lie in a silicon-carbon hybrid anode, made with nanostructures that store more lithium ions, while reducing the potential for damage as the silicon expands. These hybrid nanostructures include silicon-coated carbon nanotubes, core-shell nanostructures, and carbon coated silicon nanowires grown by electrospinning or by the vapor-liquid-process. Cyclohexasilane, CHS, enables commercially viable approaches to manufacture these nanostructures due to its ability to be readily functionalized, more ideal handling conditions, and more favorable reaction conditions. All of these merits could result in single-step processing and roll-to-roll manufacturing. This “drop-in” replacement to existing manufacturing processes would offer a means to reduce costs and avoid using CVD methods that have high capital costs.
The figure below highlights the merits of this approach, illustrating that with relatively low silicon incorporation into the anode structure, an increase in the energy density by roughly 3x is readily achieved, while maintaining good cycle life.2
Moreover, the resulting silicon nanostructured morphology can be readily tailored to deliver nanofibers or nanoparticles with a desired size and conductive carbon additive. Silicon thin films are also a possibility, and we envision deposition mechanisms that alleviate some of the delamination issues that have plagued previous efforts.
Should be another great week as Coretec moves forward with the commercialization of Si6H12 ! Expecting great things soon !! Its going to happen , partnerships Joint development agreements and the announcement of who the new chemical manufacturer is with terms of that agreement which Coretec said was a WELL RESPECTED MAJOR CHEMICAL MANUFACTURER ,I BELIEVE THESE THINGS THE COMPANY HAS SPOKEN OF IS COMING AND NOT TO FAR AWAY !!!!
The overall theme of The Battery Show was improving battery technology, and a clear example of this was the prevalent discussion for how to use silicon to get the most gain in Power Capacity (Watt Hours). Coretec met with several companies eager to evaluate and leverage CHS’ value in making their own advanced Li Ion batteries. As a logical next step, Coretec will work with them to cement plans to evaluate CHS as a premier Si precursor to improve the performance of their next generation Li Ion battery.
As we have mentioned, we have continued to host discussions with several Si anode customers in consumer electronics and EV and they agree that based on several unique and novel methods to impart Si into the graphite anode, the path to higher energy density is silicon.

“Commercial success for the Company hinges on its technological advances as well as its ability to increase visibility in the market and create meaningful relationships with potential partners and customers,” said Michael Kraft, CEO of The Coretec Group. “We also understand the importance of maintaining effective communications with shareholders, and have placed an emphasis on doing so using several mediums. We are excited about the progress made to convert ongoing high level conversations with partners and customers into agreements that we believe will commercialize and scale our silicon-based material technologies.”
“We are confident that battery manufacturers and end-use customers alike will continue to pursue integrated technologies for next generation battery design that does not disrupt the current manufacturing process,” said Michael Kraft, CEO of The Coretec Group. “The Battery Show is an ideal venue for us to showcase our vision for commercializing silicon-based anodes capable of delivering greater energy density and longer life while charging faster. We will also continue to strengthen our industry relationships and advance discussions, hopefully resulting in a not-too-distant joint development venture between Coretec and an ideal partner to help us test and scale the technology.”
Coretec has great potential in the semi conductor market !!!
A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current. Its conductance varies depending on the current or voltage applied to a control electrode, or on the intensity of irradiation by infrared (IR), visible light, ultraviolet (UV), or X rays.
The specific properties of a semiconductor depend on the impurities, or dopants, added to it. An N-type semiconductor carries current mainly in the form of negatively-charged electrons, in a manner similar to the conduction of current in a wire. A P-type semiconductor carries current predominantly as electron deficiencies called holes. A hole has a positive electric charge, equal and opposite to the charge on an electron. In a semiconductor material, the flow of holes occurs in a direction opposite to the flow of electrons.
Elemental semiconductors include antimony, arsenic, boron, carbon, germanium, selenium, silicon, sulfur, and tellurium. Silicon is the best-known of these, forming the basis of most integrated circuits (ICs). Common semiconductor compounds include gallium arsenide, indium antimonide, and the oxides of most metals. Of these, gallium arsenide (GaAs) is widely used in low-noise, high-gain, weak-signal amplifying devices.
A semiconductor device can perform the function of a vacuum tube having hundreds of times its volume. A single integrated circuit (IC), such as a microprocessor chip, can do the work of a set of vacuum tubes that would fill a large building and require its own electric generating plant.

Small-angle X-ray scattering (SAXS) data is taken of coin cells with nanostructured negative electrode materials such as SnCoC. Coin cells are made with Beryllium (transparent to X-rays) windows and are connected via an external cable to chargers in the main lab. X-ray information is collected as these in-situ cells charge and discharge, and the result is modeled and combined with voltage data to give a quantitative look into the behaviour of the nanostructured material upon lithiation and delithiation.

Fade mechanisms in Li-ion cells with Si-alloy containing negative electrodes
Li-ion batteries are now used in a wide variety of applications. However, energy density (amount of energy stored per unit volume) still needs to be improved. As such Si alloy materials are of interest for their high volumetric capacity (˜3 times that of the widely used graphite material).
Li-ion cells that contain Si-based materials typically show rapid capacity fade (amount of Li exchanged from the positive electrode to the negative electrode during one charge or one discharge). Understanding why this rapid capacity fade occurs is of upmost importance.
In order to understand this fade mechanism cells containing a negative electrodes consisting of a blend of Si alloy and graphite and a positive electrode consisting LiCoO2 were filled with the same electrolyte and cycled for various amount of time and various rates (currents of various amplitudes). The electrolyte used contained 10 wt% fluoroethylene carbonate (FEC), an additive that has been widely reported as extending lifetime of cells containing Si-based negative electrodes.
Figure 1a shows the capacity vs. cycle number of cells cycled at C/2 and 20°C. Figure 1a shows that cells present a steady initial capacity fade during the first 350 cycles followed by a sudden failure. In order to understand this fade, the composition of the electrolyte was analyzed by gas chromatography. Figure 1a shows that the cell that underwent 100 cycles had only 5.3% of the additive FEC left out of the initial 10%. Figure 1a also shows that the cell that was stopped right before sudden failure had only 0.9% of the additive left while the cell that was stopped after failure had none left. This clearly shows that the additive is consumed rapidly and that its presence in the electrolyte is necessary for cells to function relatively well. Once the additive runs out, the cell undergoes sudden failure.
Figure 1b shows the cell capacity vs. cycling time for cells that were cycled at various rates. Figure 1b shows that cells cycled the fastest (C/2) show more fade for a given cycling time than cells cycled more slowly. If cycling time was the only factor dictating early capacity fade, cells would have the same capacity fade for a given cycling time regardless of their cycling rate. This indicates that some of the fade in Si-containing cells has a cycle-number dependence. This can be understood from the fact that Si or Si-alloy expand upon lithiation (charge) from 120% to 280% of their initial volume. This large volume expansion induces cracks in the protective layer at the surface of the particles. This protective layer is made via the degradation of the electrolyte which produces compounds that precipitates at the surface of the particles thus protecting the electrolyte from further degradation. The creation of this protective layer consumes active lithium. Each time this protective layer cracks upon particle expansion, more active lithium is consumed to regenerate this protective layer. The consumption of active lithium is at the origin of the capacity fade.
The design of Si-containing cells with long lifetime then needs electrolyte that reduces the consumption rate of FEC or uses another passivating agent, as well as uses a combination of electrolyte composition and active material design that reduces the amount of cracks in the protective layer generated by the expansion of the Si.

Additives to the electrolytes of Li-ion cells and coatings on the surfaces of electrode particles are known to dramatically effect the lifetime and cycle life of Li-ion cells. High precision coulombic efficiency measurements allow the rapid ranking of the effectiveness of electrolyte additives and surface coatings. Fundamental studies using surface-sensitive techniques are now being established to understand how additives and coatings work with the ultimate goal of finding additives that make Li-ion cells last many decades!

From the Corporate update we can see Coretec is set to become a leader in the silicon materials space !!! Cortetec on the way to becoming a very successful company !!
Coretec’s lead product candidate is cyclohexasilane or Si6H12 (CHS), a liquid that converts to poly-silane when exposed to heat or UV irradiation, followed by conversion to amorphous silicon and ultimately crystalline silicon. The Coretec group believes further development and eventual commercialization of the product will result in improved performance, reduced cost, simplified manufacturing, and safer handling when compared to the more traditionally used mono-silane.
There are many potential advanced applications for CHS, spanning the high growth industries of solar energy, energy storage, sensors, volumetric imaging and semiconductors, among others. For example, battery manufacturers and application developers for a number of industries’ increased dependence on lithium, cobalt and other minerals have caused the cost of these battery components to rise, ultimately impacting the overall cost of the application itself. CHS represents an alternative to many of these mineral components, with the potential to both increase efficiency and output while simultaneously driving down cost.
Led by its VP of technology, Dr. Ramez Elgammal, the Coretec Group has continued to establish strong relationships with partners and customers, including both original equipment manufacturers (OEMs) and the product support value chain in key industries such as electric cars, personal electronics, semiconductor, solar, and LEDs. In May, Dr. Elgammal attended The Battery Show Europe where he observed strong interest in new anode materials to deliver greater energy density, and longer lasting and faster charging batteries, especially silicon-based ones. Many groups he spoke with expressed interest in integrated technologies that use silicon-based anodes to design next generation solid-state batteries, and view Coretec’s CHS as a potential key to reaching that objective.

We believe CHS will catalyze new performance innovations in energy storage, and several of our customers think this as well. Our stated goal is to achieve approximately 200% improvement in performance, however, we expect these increases to be incremental, such as 30% improvements, then another 30% more, and so on. Cost will be determined by the markets, as there will be higher prices paid for larger performance initially (likely EV), and then filter into distributed renewables, and finally into commodity electronics. Of course, that changes if consumers are willing to pay $200 more for a smartphone that lasts several days on a single charge.
As we have mentioned, we have continued to host discussions with several Si anode customers in consumer electronics and EV and they agree that based on several unique and novel methods to impart Si into the graphite anode, the path to higher energy density is silicon.

CEO BLOG from Sept 4th Big Times ahead for Coretec !!!
In addition to Dr. Elgammal’s presentation, he and Kraft will continue to pursue introductions to global manufacturing partners and companies with end-user applications that have a growing need for a better silicon precursor, such as electric vehicle and portable electronics. With over 8,000 in attendance, this event is a significant opportunity to form relationships that represent value throughout the battery supply chain.
“We are confident that battery manufacturers and end-use customers alike will continue to pursue integrated technologies for next generation battery design that does not disrupt the current manufacturing process,” said Michael Kraft, CEO of The Coretec Group. “The Battery Show is an ideal venue for us to showcase our vision for commercializing silicon-based anodes capable of delivering greater energy density and longer life while charging faster.

As Michael Kraft has mentioned it takes patience to commercialize a new material . Thank goodness Coretec is not in the R&D phase of creating a product but have Si6H12 ready for commercializsation today !! That's huge for us and to here of all the many customers Cortec has I assume all under NDAs at this point is extremely encouraging and a great testament to the value of CHS . I think we could hear very near term who Coretecs new Major Chemical Manufacturer Partner is and hopfully they can name who they are or have shipped out materials to if that's allowable under the agreements Coretec has with thier customers which it looks as if they a lot of . Management has made significant progress in a short amount of time for a new technology and has Coretec setting up for a very successful future !!

b]Thereby, replacing graphite with silicon raises the capacity of the battery by 10 times. This is expected to raise the demand for silicon as an anode material in lithium-ion batteries in the long run.
Great market report supporting Coretecs New material need in todays technologies !!
Lithium-ion batteries have established their place as the leader in the power and energy densities for mobile applications. The global lithium-ion battery market is anticipated to witness a relatively strong growth over the coming years due to its extended penetration in electronics industry, especially in smartphones. Exploitation of natural sources for graphite production coupled with strict regulations pertaining to the production of natural graphite is anticipated to result in short supply of graphite. The need for substitute sources has augmented. Upsurge in demand for lithium-ion batteries is likely to be soon challenged by the development of next-generation batteries. Silicon anode batteries are expected to foresee extensive growth owing to the added advantages that they provide with such as enhanced performance capacity of silicon and low use of the anode material.
Consumer Electronics Industry to Surge Ahead of Others in Terms of Adoption
The global smartphone consumption is projected to expand at an outstanding rate with its consumption growing extensively in 2018. Currently, thinner, lighter, and faster smartphones with relatively advanced features have been developed and preferred more by the consumers across the globe. Nevertheless, manufacturers have been unable to improve the battery capacity as per the requirements. Operations such as video streaming, playing high graphic resolution games along with RAM/ROM utilization, and others reduce battery performance. Moreover, graphite anode’s performance in the lithium-ion batteries reaches its ultimate capacity in almost 1000 cycles. Thereby, replacing graphite with silicon raises the capacity of the battery by 10 times. This is expected to raise the demand for silicon as an anode material in lithium-ion batteries in the long run.

?Silicon Anode Battery Market
Future Market Insights (FMI) has published a new research report on silicon anode battery. The report has been titled, “Silicon Anode Battery Market: Global Industry Analysis (2013–2017) and Opportunity Assessment (2018–2028).” Silicon anode battery market is professed to be in its preliminary stages of growth as paralleled to other conventional batteries. The replacement of graphite anode with silicon is anticipated to be one of the biggest trends in the global battery market. According to the report, the market is expected to witness a Herculean CAGR of 20.8% from 2018 to 2028. The market was worth US$ 126.4 Mn in 2017 and is projected to touch a valuation of US$ 982.6 Mn by the end of 2028.
The burgeoning production of smart consumer electronics along with devices such as motion sensors, and GPS, among others has led to a rise in the demand for efficient battery solution that can maintain decent battery life while running high power consuming applications. The rapidly growing shipment of electronic devices, and appliances will be the key driving factor for the global silicon anode battery market. Substantial growth in the service and manufacturing sectors has led to a healthy growth in GDP worldwide. This, in turn, has had a positive impact on the global spending on smartphones, thereby eventually impacting the demand for silicon anode battery. As a result of the above, companies operating in the market are focusing on product development, plant expansion, and mergers and acquisitions. For instance, in October 2016, LG Chem inaugurated an automotive battery manufacturing plant in Poland to expand and strengthen its market presence. Other companies operating in the market are XG Sciences, Nexeon Limited, Enevate Corporation, Nanotek Instruments, Inc., Panasonic Corporation, Zeptor Corporation, and Amprius, Inc., among others.
Electronic Miniaturization to Trigger Market Progress:Silicon anode batteries are expansively employed currently as a power source in portable consumer electronics and automotive, such as 3G cell phones, tablets, laptops, MP4 players, and digital cameras, hybrid electric vehicles and electric bicycles due to their high voltage, long life span, and high energy density. With reference to miniaturization, development of micro-batteries or thin-film batteries for implantable restorative devices and MEMS (micro electro mechanical systems) is expected to propel the market for silicon anode batteries. This nanotechnology and micro electromechanical systems (MEMS) are increasing in functionality as well as approval in a bulk of applications among various industries, such as consumer electronics, aerospace, automotive, and medical devices and others. The present pace of miniaturization of electronic devices will result in a surge in demand for silicon anode batteries in near future. Similarly, miniaturization of electronic devices, such as laptops, smartphones, consumer electronics, etc. has led to an augmented usage of silicon as an anode in lithium-ion batteries.
Nascent Adoption to Pose Limitation to Market Growth:The lithium-ion battery market has taken off over the last ten years. This gush in demand was mainly owing to its uptake in smartphones. Despite the fact that lithium-ion chemistry was invented back in 1970s, its first commercialization was done in the early 1990s. Nevertheless, it is assessed that the introduction of novel products in the niche battery sector will take comparatively a longer time span to commercialize. It is thereby anticipated to follow the same inclination as the lithium-ion batteries market, which is expected to encounter the growth of the silicon anode battery market in the near future.
Great article from the interview with Michael Kraft the #1 CEO in America last July !!! GREAT INSIGHT INTO THE GREATNESS THAT AWAITS US FROM CORETECS NEW MATERIALS !!!
Tell us about The Coretec Group and its mission.
The Coretec Group’s mission is to commercialize innovations and disruptive technologies in silicon (Si) and 3D visualization, serving advanced technology markets in support of global challenges in energy, electronics, semiconductor, solar, health, environment, and security.
The Coretec Group has really focused on CHS technology? Tell us about CHS Technology.
CHS, or cyclohexasilane (Si6H12), is an excellent Si precursor, many say the best source for the atom Si. The silicon atom has wide ranging chemical characteristics; from semiconductor chips to silicone caulk to Si oxide (glass). We have many critical materials today that owe their material performance to the silicon atom. Coretec is committed to supplying the best Si precursors for next generation advanced materials and systems, primarily focused on technology markets that need a step function in innovation to reach tomorrow’s solutions.
What benefits can this form of CHS bring to alternative energy markets?
CHS is a liquid up to 175F, which means it can enable room temperature liquid silicon precursor processing; thereby reducing processing costs. In some applications, it can enable unique material properties not achievable with other silicon precursors; which means CHS can deliver unique performance characteristics in the customers application. It starts with this: CHS is a ring of six Si atoms, all six Si atoms have two Si bonds, and the other two bonds to each Si atom are hydrogens. The silicon-hydrogen bonds in this molecular structure are weaker compared to conventional Si precursors due to the molecule’s geometry, which means it is easy to remove the hydrogen and all that is left is PURE Si. Moreover, the unique CHS structure enables preferential formation of Si structures compared to traditional materials such as silane, SiH4. A liquid Si precursor at room temperature, with an easier transformation to pure silicon are some of key advantages of CHS with the added bonus of a lower transition temperature to amorphous Si (a-Si) and crystalline Si (c-Si).
This means CHS-derived Si nanoparticles have many advantages over other Si nanoparticles, AND CHS is more easily functionalized (combined with other atoms, like boron) leading to unique chemical compounds that can deliver tailored Si-materials. Better Si nanoparticles and better Si quantum dots (QDots) make better Si anode batteries, better solar cells, better LEDs, better QDots for drug delivery, and many other uses.
Tell us about the cost savings of CHS as related to energy storage.
The Energy Storage Market needs better batteries. Lithium-ion batteries can realize significant improvements in storage capacity by using Si anodes, and CHS can enable that in two ways. First in process ability; CHS can coat carbon nanoparticles as a liquid, making the coating process faster and cheaper. Second, with some unique processing, CHS can readily form Si nanoparticles which can address the issue of expansion and contraction experienced in charging and discharging Si anode lithium-ion batteries. A lithium-ion battery, however, with a Si anode has the potential to achieve a 300% increase in power density (300% more power output in same size/weight battery). We could also reduce battery weight and attain a significant increase in power. Think of an electric car battery half the size but with a 150% increase in power & distance. All other things being equal, that 200-mile EV range just turned into 500 miles.
How is The Coretec Group working to leverage this technology?
We are working with leading energy storage companies to help them take advantage of the CHS material characteristics mentioned above, as well as other innovators in the other markets mentioned that span a number of applications.
I would like to make a key point here: Coretec is not betting on which product design will win a majority of the market, as we are not a one-product, nor one-market participant. For example: there are dozens of Si anode battery designs out there, however, we are working with several of them, and anticipate there are more that will realize they need a better Si precursor. This increases our chances of being a part of the winning Si anode battery. We anticipate doing this in a similar manner for all markets which need a better Si precursor.
What can this mean for the future of energy storage?
In energy storage, there is a tremendous demand for improved performance in a multi-billion-dollar market. When one combines EVs, distributed renewables, and personal electronics, it reaches the tens of billions. That demand for increased performance has resulted in billions being spent right now on innovation.
We believe CHS will catalyze new performance innovations in energy storage, and several of our customers think this as well. Our stated goal is to achieve approximately 200% improvement in performance, however, we expect these increases to be incremental, such as 30% improvements, then another 30% more, and so on. Cost will be determined by the markets, as there will be higher prices paid for larger performance initially (likely EV), and then filter into distributed renewables, and finally into commodity electronics. Of course, that changes if consumers are willing to pay $200 more for a smartphone that lasts several days on a single charge.
What other industries and uses are there for CHS?
There are many, and probably a few we have not thought of yet.
Semiconductor. Purity and yield are key performance criteria in semiconductors. Our molecule can deliver best-in-class purity based on Si6H12, and with six Si atoms per molecule, it can also deliver superior yield and productivity (meaning lower cost). There are other advantages in some semiconductor processing where there are needs for lower temperature conversion to pure silicon.
Solar: Performance can be improved using QDots (5-50nm Si nanoparticles). Si QDots have tunable bandgaps across a wide range of energy levels where light is captured or expelled by changing the dots' size. This property makes quantum dots attractive for multi-junction solar cells, where a variety of materials are used to improve efficiency by harvesting multiple portions of the solar spectrum, hence can improve a solar cell’s performance by as much as 10%.
Drug Delivery: Si QDots can carry pharmaceuticals / drugs and act as the delivery vehicle into the body. Their optical properties can be used to trace the accumulation of the drug in the specific areas of the body. This is of particular value in tracking the efficacy of the drugs used and can aid in the management of dosage.
LED: When an LED backlight hits a quantum dot, it glows. The size of the dot dictates the color—the biggest, at 5.5 nanometers, handle pure reds, smaller dots handle pure green, and the LED backlights handle the blues. In new TVs (Samsung's Q-Series), the quantum dots are arranged in a film that fills the screen. Once the backlight activates them, their light passes through the filters that render the colors you see watching the TV. This improves efficiency—instead of having to divide white light, which represents all the wavelengths of light, into precise colors, the filters in a quantum-dot set work with pristine colors and color hues. No light is wasted, resulting in brighter, more accurate colors. This is expanded to LED displays, dashboards, computer screens, and signs. Innovation to sharper colors, brighter colored LEDs, and with less power – that is what is happening.
Agree !! Should be some big announcements coming soon with the Chemical manufacturer to be named at some point and with Coretec cementing plans to work with several companies !!
