| titleOfInvention | Method for recovering valuable metals from waste lithium ion batteries |
| abstract | The invention belongs to the technical field of waste lithium ion battery recovery, and particularly relates to a method for recovering valuable metals from waste lithium ion batteries, which comprises the following steps: (1) preparing an adsorption carrier; (2) fully discharging the waste lithium ion battery, taking out the anode material of the lithium ion battery, and putting the anode material into a ball mill to be crushed to obtain a powder mixture with the particle size of less than 0.5 mu m; immersing the powder mixture into 3-5 times of alkaline solution, continuously adding an adsorption carrier during stirring, filtering to obtain an adsorption carrier rich in metal ions, and eluting the adsorption carrier with an acidic solution to obtain a solution rich in metal ions; according to the invention, the adsorption carrier is used for separating and enriching metal ions in the waste lithium ion battery, so that the recovery efficiency of metal is improved; meanwhile, only acid-base solution is used in the recovery process; the used adsorption carrier can be repeatedly used, and the metal recovery cost is reduced. |
