Abstract

See full text

Provided is a spinel-type lithium metal composite oxide that makes it possible to achieve excellent high-temperature storage characteristics when used as a positive electrode active material of a lithium battery. The spinel-type (Fd-3m) lithium metal composite oxide is characterized by the oxygen occupancy (OCC) thereof as determined by the Rietveld method being 0.965-1.000, the lattice strain thereof as determined by the Williamson-Hall method being 0.015-0.090, and the ratio (Na/Mn) of the molar content of Na to the molar content of Mn satisfying 0.00−2.
