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 body 300 having a sealing cap 320 on the upper section and an agitator 130; an outer reaction container 200 installed inside the reactor main body 300; and an inner reaction container 100 installed inside the outer reaction container 200. The inner reaction container 100 comprises a plurality of holes on the upper section and a separating cap 240.
