Method of manufacturing electrode active material, method of manufacturing secondary battery, and secondary battery

Abstract

A method of manufacturing an electrode active material in an efficient manner is accomplished by recycling an exhausted active material contained in an electrode of a spent secondary battery through a simple process with reduced environmental impact such that the resulting active material can be reused. A method of manufacturing an electrode active material is a method of manufacturing an electrode active material by recycling an exhausted active material contained in an electrode of a spent secondary battery such that the resulting active material can be reused, the electrode including a current collector and an electrode mixture containing the active material and formed above the current collector, the method including: immersing the electrode in an alkali aqueous solution to peel the electrode mixture from the current collector (step 1); and neutralizing the peeled electrode mixture (step 2).
