| titleOfInvention | Recovery method of waste lithium battery anode material, spherical nickel oxide material and application |
| abstract | The invention provides a recovery method of a waste lithium battery anode material, an obtained spherical nickel oxide material and application. The recovery method comprises the following steps: (1) disassembling to obtain a positive plate; (2) soaking the positive plate to obtain a positive active material; (3) oxidizing and roasting the positive active material to obtain first roasting slag; (4) reducing and roasting the first roasting slag to obtain second roasting slag; (5) leaching the second roasting residue to obtain a first mixed solution; (6) supplementing corresponding metal elements into the first mixed solution according to the element proportion of the target product to obtain a nickel-cobalt-manganese mixed solution; (7) respectively and simultaneously adding the nickel-cobalt-manganese mixed solution, ammonia water and a carbonate/bicarbonate solution into a reaction container for reaction to obtain carbonate precipitate; (8) and (3) inert roasting the carbonate precipitate to obtain the spherical nickel oxide material. The spherical nickel oxide material obtained by the recovery method can be used as a lithium battery negative electrode material, and has excellent specific mass capacity and rate capability when being used as the lithium battery negative electrode material. |
