Abstract
The present invention provides a cathode electroactive material comprising a composite oxide comprising .beta.-MnO.sub.2 and a spinel oxide predominantly comprising lithium, manganese, and oxygen. The present invention provides a process for producing said material, which process comprises acid treatment of a composite oxide comprising a spinel oxide predominantly comprising lithium, manganese, and oxygen, and heat treatment of the resultant composite oxide at a temperature of about 200.degree. C. or higher and lower than about 400.degree. C. The thus-produced oxide is employed as a cathode electroactive material in a non-aqueous secondary cell.
