The problem is there is no real infrastructure to recycle the stuff so it just ends up in landfills with the associated pollution from discarded batteries.
There are processes to recover raw materials from Li-Ion cells: freeze them to decrease electrolytic reactions, shred them and separate the bits mechanically (using computer vision) and chemically. Very expensive and risky.
