ACTIVE MATERIALS FOR LITHIUM-ION BATTERIES

摘要

Methods for forming a cathode active material comprise sintering flakes formed from a nickel, manganese, cobalt and lithium-containing slurry to form the cathode material having the formula Li2Ni1-x-yMnxCoyO2, wherein 'x' is a number between about 0 and 1, 'y' is a number between about 0 and 1, and 'z' is a number greater than or equal to about 0.8 and less than 1. Lithium-ion batteries having cathode active materials formed according to methods of embodiments of the invention are provided.
