ALUMINUM SUBSTITUTED MIXED TRANSITION METAL OXIDE CATHODE MATERIALS FOR LITHIUM ION BATTERIES

摘要

A mixed transition metal oxide is provided described wherein Aluminum is partially substituted for Cobalt in a Li[NixCOyMn2]O2 composition wherein the resulting aluminum substituted product is less costly than the parent product, is safer to use, and provides enhanced electrochemical performance as a cathode material for use in Lithium-ion based batteries.
