Sila Nanotechnology has silicon-led anode products that fall into the existing battery manufacturing process, completely replace graphite, and provide significantly higher energy density at the battery level with lower expansion.

　　Sira Nanotechnology Company has silicon-led anode products, these products fall into the existing battery manufacturing process, completely replace graphite, and provide significantly higher energy density at the battery level, and have a lower expansion.

　　SilaNanotechnologies emerged from the stealth mode last month and will cooperate with BMW to apply the company's silicon-based anode materials to at least some German car manufacturers' electric vehicles by 2023. A BMW spokesperson told the Wall Street Journal that the company expects the transaction to increase the amount of energy that can be loaded into a given volume of battery by 10 to 15%. Syrah CEO Gene Berdichevsky said that these materials may eventually produce a 40% improvement.

　　Sira Nanotechnology company designed a method to change the internal structure to prevent the battery electrolyte from infiltrating into the particles, and achieved dozens of incremental increases in energy density, which was finally about 20% higher than the existing best technology.

　　Finally, Sila created a solid, micron-sized spherical particle containing a porous core that can channel most of the swelling in the internal structure. The outside of the particles will not change shape or size during charging, thus ensuring normal performance and cycle life.
