POSITIVE ELECTRODE ACTIVE MATERIAL, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing technology for inexpensively manufacturing a positive electrode active material having sufficient charging and discharging capacity.

SOLUTION: A method for manufacturing a positive electrode active material is a method for manufacturing an active material that contains lithium and fluorine as constituent elements and becomes a positive electrode of a nonaqueous electrolyte secondary battery. The method comprises the step of obtaining the positive electrode active material by dipping a solid object that contains sodium and fluorine as the constituent elements and becomes a precursor of the positive electrode active material into an organic solvent containing an electrolyte which contains lithium. The electrolyte containing lithium, and the organic solvent are used as an electrolytic solution of a nonaqueous electrolyte lithium ion secondary battery.
