COST EFFECTIVE SYNTHESIS OF OXIDE MATERIALS FOR LITHIUM ION BATTERIES

Abstract:

Methods for synthesizing crystalline Ni-rich cathode materials are disclosed. The Ni-rich cathode material may have a formula LiNixMn.sub.yM.sub.zCo.sub.1-x-y-zO.sub.2, where M represents one or more dopant metals, x.gtoreq.0.6, 0.01.ltoreq.y<0.2, 0.ltoreq.z.ltoreq.0.05, and x+y+z.ltoreq.1.0. The methods are cost-effective, and include methods for solid-state, molten-salt, and flash-sintering syntheses.
