Description

Technical field

[0001] The invention belongs to the technical field of lithium battery recycling, and specifically is a lithium battery recycling process. Background technique

[0002] Due to the shortage of resources and the need for environmental governance, countries all over the world attach great importance to the recycling and utilization of waste batteries. The management of waste batteries is of urgency. How to recycle and harmless waste batteries is imminent. The existing lithium battery recycling devices adopt Pyrometallurgical and hydrometallurgical processes, a large number of mixed and recycled lithium batteries are only treated in a mixed and indiscriminate manner, and then chemical precipitation and solvent extraction methods are used to separate rare earth elements, impurities, nickel and lead elements in acid solutions Requires secondary processing, cumbersome steps and low processing efficiency, which in turn affects the recovery efficiency of lithium battery ca...
