February 28, 2022 – The Coretec Group, Inc., (OTCQB: CRTG), a developer of engineered silicon and 3D volumetric displays, has filed a full utility patent on its provisional patent for the development of advanced silicon anodes using cyclohexasilane (CHS) and other silanes.

The full-utility patent – filed February 24, 2022 – builds on a provisional patent filed a year earlier. This patent application covers the use of CHS to produce a wide variety of silicon anodes for use in lithium-ion batteries.

If CHS is used in the new battery anode which it is then creating a cost effective process to scale CHS looms big for the company since that will be part of the cost of a full battery cell. Of coarse they said they are using other silanes as well but havnt said what they are unless they are in the patent they filed in Feb. Will have to look. Im sure someone will pay extra for Coretecs battery if it does outperform other batteries in all 3 areas , energy density , faster charging and longer battery life. Michelle mentioned a while back that after testing is done they will continue to optimize the battery with their battery manufacturer. Hopefully they will release some testing data after January testing is done a the Michigan battery lab. Its great to see from the patent last Feb that they are making a wide variety of silicon anodes using CHS and other silanes. They must believe they have something VERY special since Corwtec said they will revolutionize the battery EV business and i dont think they are just trying to hype this i think they truely believe this. One of the big differences for Coretec is not just their Liquid silicon they have vs the gaseous silanes but this bottom up approach where with chemistry they are customizing from scratch silicon nanoparticles ( SiNP ) and making SiNP so small they help solve the expansion problems with silicon and the SEI protective layer aroung the SiNP. I believe in the last update they had a chart which showed the size of NP aroung 50nm but one also that showed Corerecs from 2-50 nm. in size 2nm is extreemly small. Ill have to look back at that . Also they said with traditional silanes even they are difficuly to " functionalize " perhaps after the ball milling process is used to create them . Coretec having their own process to create their smaller nanoparticles is i assume patented and could be a big deal in future creation in SiNP for many applications. Thet did mention that one reason semi conductor companies are interested in Coretecs CHS is that its a liquid state vs the gaseous silanes. I hope they get the money from the Chips Act so thety can continue to refine the process to create CHS for a more cost effective product. My bet is that they will be successful in doing that . The CEA and Eindhoven have both already said that CHS was used to successfully create SiNP that were better that Monosilane ( the most widely used and it coined the phrase silicon valley ) Disilane neo pentasilane and all the silanes the CEA had wi=orked with . Thats a big deal . Now successfully refining a cost effective process could be huge going forward for the CHS project. Richmond chemical was originally working on the process to scale CHS but apparently there is work to be done to fully accomplish that in a cost effective manner.
