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:{Li}[Lix.My.Mn(2&#8722;x&#8722;Y)]O4+dwherein { } represents the oxygen tetrahedral sites in the spinel structure and [ ] represents the oxygen octahedral sites in the spinel structure, 0<x&lE;0.33, 0<y&lE;1.0, &#8722;0.5<d<0.8, and M represents at least one heteroelement other than Li and Mn, is disclosed.
