Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To manufacture a positive electrode active material for a lithium ion battery having excellent battery characteristics with excellent manufacturing efficiency and at a manufacturing cost.SOLUTION: Disclosed is a method of manufacturing a positive electrode active material for a lithium ion battery, which includes the steps of: obtaining a metalhydroxide by adding ammonia water to an aqueous solution of a mixture of nickel sulfate, manganese sulfate and cobalt sulfate, and adjusting the aqueous solution of the mixture to pH10 to 12 by adding a lithium hydroxide thereinto while agitating them; obtaining mixed powder of the metalhydroxide and lithium carbonate by mixing the metalhydroxide and the lithium carbonate; and calcinating the mixed powder.SELECTED DRAWING: None
