Funny you should mention that. There is a company that can now turn(recycle) even electric car batteries into fuel. It takes a super high temperature to do it and other little tricks as well but it is doable.
This is one of the former founders of Tesla they are in the power industry they rebuild packs and repurpose cells to other uses them when they finally reach end of life they fully recycle them and by them I mean any chemistry NMC.LION,LFP the works right back into American made power cells.
The modern world cannot exist without high density power cells. Every electronic device is dependent on them and most simply couldn’t exist without them. Your smartphone for one, tablets, laptops, medical devices, drones, probes, ocean buoys, diesel electric submarines that are not wwii clunckers the list is endless and it’s a trillion dollar industry just for those things aline. EVs are only 6% of the power cell market and it’s a trillion plus dollar market.
