COMPOSITE METAL OXIDE, PROCESS FOR PRODUCING THE COMPOSITE METAL OXIDE, POSITIVE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY, POSITIVE ELECTRODE FOR SODIUM SECONDARY BATTERY, AND SODIUM SECONDARY BATTERY

WIPO Patent Application WO/2012/060295

A1

Provided are: a composite metal oxide with which it is possible to improve the performances of a sodium secondary battery; a process for producing the composite metal oxide; a positive active material which comprises the composite metal oxide; a positive electrode produced using the positive active material; and a sodium secondary battery equipped with the positive electrode. The composite metal oxide is represented by formula (I) and is configured of an oxide having a P2 structure and a lamellar oxide having an octahedral structure and/or a triangular-prism structure, which each functions as a stacking fault. The lamellar oxide preferably is an oxide having an O3 structure.
