Tracing the technological progress of Energy storage in India, could the next big technological revolution be in the storage of solar energy?
When the sun doesn’t shine? The world we live in operates 24/7, battery storage technologies are emerging as a critical part of the solution to increase access to electricity in conjunction with solar PV in solar home systems, as well as providing stability services to mini-grids, improving the power quality and increasing the potential share of variable renewables in such remote grids. XNRGI is on the cusp of one of the fastest, deepest, most consequential disruptions of energy storage in history. The lithium battery technology is at the crossroads. The fundamental limitations and outdated electrode manufacturing methods have considerably slowed down the progress. The expected improvements in performance have not happened and the hope for breakthroughs towards new active materials is not likely. A battery is considered the weakest link in many flourishing applications such as electrical vehicles and other mobile applications; and the obstacle towards widespread proliferation of groundbreaking devices. And while the battery industry stagnates, the next 4th industrial revolution will not wait, and it desperately demands a better, lighter, and cheaper portable power source that scales across ever increasing energy storage needs from transport, consumer electronics to the grid. The electrical vehicle application in particular is on a high trajectory towards completely taking over the vehicle industry, but it needs a battery that will match the demand. Present battery technology is not capable of manufacturing scale to meet the demands of the application in terms of energy density, cycle life, safety or cost.
“India’s total demand for energy will more than double by 2030, while electricity demand will almost triple This assumes sufficient uptake to double the share of renewables in the global energy mix in less than a decade and a half. With growing demand for electricity storage from stationary and mobile applications, the total stock of electricity storage capacity will need to grow more than 150%, from an estimated 4.67 terawatt-hours (TWh) in 2017 to 12 TWh or more by 2030.”

How are you gearing up for this technological revolution?
The XNRGI (exponential energy) battery technology concept is based on a porous silicon substrate that will become the ultimate pathway towards achieving the goal of superior battery performance in a scalable manufacturing form to meet the demands of an ever-growing energy storage market in batteries. This is a novel approach for constructing electrodes and manufacturing batteries. The three-dimensional, porous structures enable several times better energies, larger number of cycles, elimination of the safety problems, and lower cost. The concept is based not on some exotic or mysterious new material, but on the well-known silicon, used in computer chips and driving or controlling practically everything in modern life. For batteries, silicon is used in form of porous wafers – the three-dimensional porous structure that enables improvements in every battery property. We have taken the idea of simultaneously improving all fundamental prosperities of batteries by using a porous conductive substrate in silicon and demonstrated the exceptional performance that is 3 to 6 times that of traditional batteries. The semiconductor industry has been a dominant driving force behind modern technology advancement for the last five decades. If one needs to point to a single reason for this dominance, without a doubt, that would be a permanent evolution in manufacturing and semiconductor industry’s ability to innovate again and again with high volume manufacturing and achieve double win - low cost and improved performance.
What are the challenges that the sector is fronting?
High Capital Cost to Manufacture, Safety, Energy Performance Density, Installation and Integration, Efficiency, Scalability, Flexibility, Cycle Life, but most importantly Cost. Cost is key driver for all storage applications. Low cost batteries will enable 27/7 clean energy for solar.
The complexity of combinations possible between different anodes and cathodes in lithium battery systems makes it difficult to discuss the shortcomings of various batteries in general terms. But, we’ll try to point to main sources of problems that affect the performance or safety of these batteries. First, we define the performance as a totality of the following main battery characteristics*:
1. Energy density: the amount of energy stored per volume or weight.
2. Power density: the ability to deliver current per volume or weight. The ability to accept current is related to charging time.
3. Cycle life: number of cycles that a battery can deliver a useful capacity, typically 80% of the nominal or starting capacity.
4. Safety: the ability to reduce the probability of a catastrophic battery failure with violent outcome such as fire or explosion.
5. Manufacturing: cost, capacity and time to implementation.
XNRGI battery electrode technology is a perfectly scalable platform model. Flexible, Tunable, Low Cost, Safe, High Volume Manufacturing Model. The based unit or size produced is a 200 mm wafer. For applications that require larger power, full wafer electrodes can be assembled into stacks, while for smaller electrodes wafers would be cut (or diced) into any size required.
With every aspect of performance improved, the XNRGI battery concept is easily the most important battery innovation in the recent history of lithium batteries. By merging the battery industry with the silicon processing industry, the technology has the potential to harness numerous performance improvement pathways and provide a battery that will keep improving. The structure of porous silicon is extremely versatile and provides a platform, which can be continuously improved with other innovations from the battery field or semiconductor field. This is not a stagnant or limited concept; on the contrary the possibilities are almost endless towards further improvements.
