| titleOfInvention | Method and system for efficiently recovering lithium from lithium ion battery anode material |
| abstract | The invention discloses a method for efficiently recovering lithium from a lithium ion battery anode material, which comprises the following steps: (1) pretreating a lithium ion battery anode material to obtain pretreated anode powder; (2) heating and reacting the pretreated positive electrode powder with a reducing agent under the protection of inert atmosphere to obtain reduced positive electrode powder, wherein the reduced positive electrode powder contains a lithium compound easy to hydrolyze; (3) adding the reduced-state anode powder into water for hydrolysis, and controlling the pH value of a hydrolysis system to be 7-8 and the liquid-solid ratio to be (2-3): 1; (4) and (4) after the hydrolysis is finished, carrying out solid-liquid separation on the hydrolysis system in the step (3), wherein the liquid phase is the lithium ion solution. The invention also correspondingly provides a recovery system for the lithium ion battery anode material. The method has the advantages of simple process, low recovery cost, wide application range, suitability for different types of lithium cathode materials and wide market prospect. |
