Abstract
A high-performance spinel-type lithium-manganese oxide for use as a material for a positive electrode of a Li secondary battery with inhibited Mn dissolution in an organic electrolyte, which is represented by the following formula: EQU {Li}[Li.sub.x.M.sub.y.Mn.sub.(2-x-y) ]O.sub.4+d wherein { } represents the oxygen tetrahedral sites in the spinel structure and [ ] represents the oxygen octahedral sites in the spinel structure, 0<x.ltoreq.0.33, 0<y.ltoreq.1.0, -0.5<d<0.8, and M represents at least one heteroelement other than Li and Mn, is disclosed.
