METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY AND METHOD FOR PRODUCING POSITIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY

A method for producing a positive electrode active material for a lithium secondary battery capable of reducing the amount of the lithium compound to be eluted and improving the cycle characteristic and the discharge rate characteristic of a lithium secondary battery is achieved. According to one embodiment of the present invention, a method for producing a positive electrode active material for a lithium secondary battery includes a step of mixing a powder P2 having a specific molar specific surface area and containing a sulfate and/or a phosphate of a specific metal with a powder P1 containing a lithium metal composite oxide.
