A quaternary cathode composition combining nickel, cobalt, manganese and aluminum. It unites manganese's contribution to structural stability with aluminum's surface stabilization effect in a single material, an approach aimed at limiting the capacity fade seen in ultra-high-nickel cathodes. It delivers 220 mAh/g capacity at 90% nickel.
