| titleOfInvention | Method for recovering valuable metals from waste lithium ion secondary batteries |
| abstract | Waste lithium ion secondary battery is heated with superheated steam at 350 to 550 ° C., and the organic matter in the battery is pyrolyzed, then primary crushing with a crusher, primary classification at a classification point of 0.15 to 0.60 mm, on sieve Secondary crushing with a vibration mill of the current collector is sequentially performed, and the secondary crushed material is secondarily classified at the same classification point, and the residue of the positive electrode material containing rare metal is recovered from under the sieve. As a result, the organic matter in the battery can be thermally decomposed at low cost while suppressing the oxidation of metal and the generation of dioxins, and the positive electrode current collector made of aluminum does not dissolve and the recovery rate of valuable metals in the positive electrode material increases. . |
