Abstract

A method for recycling electrode materials of lithium ion batteries, including the following steps: (1) disassembling the waste lithium ion battery to get positive electrode and negative electrode, immersing the positive electrode and/or the negative electrode into ammonia, then washing by deionized water and drying the positive electrode and/or the negative electrode; (2) sintering the dried positive electrode and/or the negative electrode, and using mechanical method to separate electrode powder material from current collector to get positive electrode powder material and/or negative electrode powder material; (3) supplementing lithium to the positive electrode powder material, then processing the positive electrode powder material by milling, spray drying and sintering to obtain regenerated positive electrode material; or processing the negative electrode powder material by milling, spray drying and sintering to obtain regenerated negative electrode material. The method has advantages of energy saving, simple operation, short processing time and less pollution.
