Title: Protective coating on positive lithium-metal-oxide electrodes for lithium batteries

Abstract

A positive electrode for a non-aqueous lithium cell comprising a LiMn2-xMxO4 spinel structure in which M is one or more metal cations with an atomic number less than 52, such that the average oxidation state of the manganese ions is equal to or greater than 3.5, and in which 0.ltoreq.x.ltoreq.0.15, having one or more lithium spine oxide LiM'2O4 or lithiated spinel oxide Li1+yM'2O4 compounds on the surface thereof in which M' are cobalt cations and in which 0.ltoreq.y.ltoreq.1.
