Process for producing lithium-cobalt oxide

摘要

A process for producing lithium-cobalt oxide for use as a cathode active substance for lithium ion batteries, comprises: (a) mixing cobalt oxide having a BET specific surface area of 30 to 200 m<2>/g or an average particle size of not more than 0.1 mu m, with a lithium compound; and (b) calcining the obtained mixture at a temperature of 500 to 850 DEG C.
