Li Anode Technology for Improved Performance

A novel, low-cost approach to stabilization of Li metal anodes for high-performance rechargeable batteries was developed. Electrolyte additives are selected and used in Li cell electrolyte systems, promoting formation of a protective coating on Li metal anodes for improved cycle and safety performance.

Li batteries developed from the new system will show significantly improved battery performance characteristics, including energy/power density, cycle/calendar life, cost, and safety.
