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 cathodes from spent lithium batteries by dismantling; producing lithium cobalt oxide by reacting the cathodes 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 body300having a sealing cap320on the upper section and an agitator130; an outer reaction container200installed inside the reactor main body300; and an inner reaction container100installed inside the outer reaction container200. The inner reaction container100comprises a plurality of holes on the upper section and a separating cap240. A reaction container holder230mutually supports the outer reaction container200and the inner reaction container100.
