HIGH VOLTAGE LAMINAR CATHODE MATERIALS FOR LITHIUM RECHARGEABLE BATTERIES, AND PROCESSES FOR MAKING THE SAME

摘要

Intercalation cathode materials especially suited for use in high-voltage, high-energy lithium rechargeable batteries, having the formulae Li[Li(1-2x)/3MyMn(2-x)3Ni(x-y))O2, where 0y, and M is one or more divalent cations from Ca, Cu, Mg, and Zn. A process for making such materials is also provided.
