    Just like the periodic news about a new study on a method that makes batteries last effectively forever, this is unlikely to be implemented.

      the problem is rather to automate this and upscale this and I'm not sure how safe this method is. generally speaking if the EU makes battery recycling mandatory it definitely would benefit from a method where you don't have to grind the battery. I see this more as a PoC which can be further explored

        Oldschool lead-acid batteries need not be destroyed to be recycled. They can, and are, easily disassembled and refurbished. For all the lithium hype, lead-acid remains a valid option for non-mobile applications where storage density is not relevant.

          Where can I get cheap recycled lead acid batteries? I like them more the li-ion because they’re more forgiving to temperature changes and have a much lower chance of catching on fire

            The recycling process isn’t direct battery-to-battery. The lead from old batteries is removed, purified, dried into ingots, then sold back to battery manufacturers to make new batteries. In other words, it’s likely that every lead acid battery you buy is made from recycled batteries.

            Good rundown of the process here: <a href="https:&#x2F;&#x2F;batterycouncil.org&#x2F;battery-facts-and-applications&#x2F;how-a-lead-battery-is-recycled&#x2F;" rel="nofollow">https:&#x2F;&#x2F;batterycouncil.org&#x2F;battery-facts-and-applications&#x2F;ho...

            The same place you buy recycled steel and aluminum: anywhere that sells NEW products.
