CM3

Currently, 5V LiNi0.5Mn1.5O4 (LNMO) and xLi2MnO3·(1-x)LiMO2 (Li-rich NMC) are the lead candidates for next generation cathodes for electric vehicles. Wildcat has discovered an alternative material, CM3, based on an overlithiated spinel chemistry with promising initial performance.

Compared to the next generation cathodes, CM3 has greater energy density than LNMO and does not suffer from the voltage fade of Li-rich NMC. The novel CM3 cathode has significantly improved capacity over other materials in the market today (~ 250 mAh/g), and was the result of a high throughput screening effort involving over 4,000 cells in only 8 months.

Wildcat is interested in partnering with an industry leader to further develop and commercialize this exciting discovery.
