| titleOfInvention | Method for recovering cobalt and nickel from waste lithium batteries |
| abstract | The invention belongs to the field of lithium battery recycling, and particularly relates to a method for recycling cobalt and nickel from waste lithium batteries, which comprises the following steps: (1) crushing the lithium battery positive plate into powder particles; (2) adding the crushed particles into an excessive first strong alkali solution, stirring until no bubbles are generated, and filtering; (3) adding sulfuric acid and hydrogen peroxide into the filter cake, and filtering after the reaction is finished; (4) heating the filtrate in a nitrogen environment, adding a first strong base solution, and performing suction filtration after the reaction is finished; (5) and washing and drying the filter cake, and then detecting. Compared with the extraction-back extraction process, the method has the advantages of simple process flow, lower requirement on equipment and strong operability, and the obtained composite hydroxide is washed to realize the separation of the precious metal cobalt nickel and the low-price metal manganese, wherein the cobalt nickel content is more than 50 percent and the manganese content is less than 2 percent. |
