MANUFACTURING METHOD OF CATHODE ACTIVE MATERIAL, CATHODE ELECTRODE PLATE FOR NON-AQUEOUS SECONDARY BATTERY, AND NON-AQUEOUS SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a cathode active material capable of increasing a capacity of a non-aqueous secondary battery, a cathode electrode plate for the non-aqueous secondary battery capable of increasing the capacity of the non-aqueous secondary battery, and a non-aqueous secondary battery with a large capacity.

SOLUTION: The manufacturing method of the cathode active material 153 having a lithium-metal compound oxide as a main component is provided with a surface treatment process (step S15) in which an untreated cathode active material 154 which is formed by calcining a material of the cathode active material 153 is made to contact with a treatment aqueous solution which is adjusted to pH 10-13.
