Battery recycling approach
Source: Myth busting: Battery recycling does work - electrive.com
“We work with mechanics instead of temperature and crush the entire module in an inert atmosphere,” explains Christian Hanisch of Duesenfeld. The shredder contains nitrogen gas, which prevents further chemical reactions. The pressure is then significantly reduced, which first evaporates the liquid electrolyte and then recovers it through condensation. In addition to the grinding shredder, the electrolyte flows into a container.
The remains of the battery module and the cells are now dried and uncritical. Duesenfeld then separates the remaining mixture by proven processes such as magnets or air. The chips of the separator foil, the ferrous metals, the non-ferrous metals such as alloy and powder from lithium as well as cathode residues with nickel, manganese and cobalt remain. According to Christian...
