AI Technical Summary
Existing battery processing methods face challenges in ensuring stability during shredding and achieving high recovery rates of valuable metals like lithium, with risks of fire and inefficient lithium recovery due to lithium ions migrating to the positive electrode.
A battery shredder with a layered structure comprising a positive electrode, negative electrode, and separation membrane, where the negative electrode contains specific ratios of lithium and fluorine, allowing lithium fluoride formation in the negative electrode, which can be easily separated by water leaching.
The solution provides a stable shredding process with increased recovery rates of valuable metals by maintaining lithium in the negative electrode, preventing fire risks, and facilitating easy separation of lithium compounds.
