What are the recycling technologies for lithium batteries?

Lithium battery recycling technology 1. High-temperature metallurgy: use high-temperature roasting and simple mechanical crushing of discarded lithium batteries, and sieving to obtain fine powders containing metals and metal oxides. Characteristics of pyrometallurgical process: The process is relatively simple and suitable for large-scale processing; the combustion of battery electrolyte and other components can easily cause air pollution. 2. Hydrometallurgy: After crushing the waste batteries, use suitable chemical reagents to selectively dissolve them, and separate the metal elements in the leachate. Characteristics of hydrometallurgical process: Is the process stable enough for the recovery of small and medium-sized waste lithium batteries; the cost is high, and the waste liquid needs further treatment. 3. Physical dismantling: The battery packs are broken, sieved, magnetic separation, finely pulverized and classified to obtain high-content substances, and then proceed to the next step of recycling. The characteristics of the physical dismantling process: low processing efficiency and low time-consuming; the process is very environmentally friendly and will not cause secondary pollution to the environment.
