PURPOSE:To reduce manufacturing cost by eliminating capacity degradation caused by a charge and discharge cycle of a nonaqueous electrolyte battery formed by using a positive electrode active material mainly composed of LiCoO2, manufacturing the positive electrode active material having large discharge capacity, and manufacturing the positive electrode active material for the nonaqueous electrolyte battery by low temperature and short time baking. CONSTITUTION:Mixture of a coprecipitation body or a single compound composed of carbonate, basic carbonate, hydroxide or oxide of respective elements to constitute a positive electrode active material, is reacted with citric acid in aqueous solution or organic solvent, and created composite citric acid salt composed of lithium, cobalt and boron is baked at a temperature of 400-950 deg.C in an oxidation atmosphere. |
