I am not personally involved with recycling of batteries, but my company, Hydro, is:
Europe's largest electric vehicle battery recycling plant begins operations
"The fully automated recycling process at Hydrovolt enables up to 95% of battery metals to be recovered from batteries, including plastics, copper, aluminium and black mass, a powder containing metals of nickel, manganese, cobalt and lithium, which will be supplied to Northvolt for further recycling. Aluminium recovered through Hydrovolt will be delivered to Hydro for recirculation into commercial grade aluminium products. Several novel concepts designed to maximise recovery of materials are found within the plant, including a dust collection system which ensures valuable material typically lost through mechanical recycling steps is captured."
