Method of treating particles of cubic spinel lithium manganese oxide LMO, composition comprising particles of cubic spinel LMO enriched with lithium, mixture comprising said particles and method of making an electrode film for an electrochemical cell

摘要

A method for forming the composition stabilized against capacity degradation comprises particles of spinel lithium manganese oxide (LMO) enriched with lithium by a decomposition product of lithium carbonate forming a part of each said particle and characterized by a reduced surface area and increased capacity expressed in milliamp hours per gram as compared to non-enriched spinel.
