Apparatus and method of recovering lithium cobalt oxide from spent lithium batteries

Abstract

An apparatus and method is provided for recovering lithium cobalt oxide from spent lithium batteries. The method of recovering lithium cobalt oxide comprises the steps of: separating the anodes by dismantling the spent lithium batteries; obtaining lithium cobalt oxide by reacting the anodes with a strong alkali solution under a certain hydrothermal condition; cooling the lithium cobalt oxide to crystallize; and cleansing the synthesized lithium cobalt oxide to remove foreign objects. The apparatus for recovering lithium cobalt oxide comprises a reactor main body 300 having a sealing cap 320 on the upper section and an agitator 130; an outer reacting container 200 installed inside the reactor main body 300; and an inner reacting container 100 installed inside the outer reacting container 200. The inner reacting container 100 comprises a plurality of holes on the upper section and a separating cap 240. A reacting container holder 230 mutually supports the outer reaction container 200 and the inner reaction container 100.
