9. Battery recovery
Aluminum, copper, lithium, iron and other metal materials are recovered from discarded LiFePO4
batteries by advanced hydrometallurgical process, and the comprehensive recovery efficiency can
reach 80%. The specific process steps are as follows:
1. Recovery process and steps of cathode materials
Aluminum foil as collector is amphoteric metal. Firstly, it is dissolved in NaOH alkali solution to make
aluminum enter the solution in the form of NaAlO
