Publication number: 20240128531Abstract: The present disclosure discloses a method for recycling all types of lithium batteries. First, the lithium battery waste is acid-leached to obtain a solution containing most of metal ions. After filtering, the solution is separated from the remaining solids, and then the obtained solution is subjected to separate precipitation many times.
