@jcrabapple@dmv.community Interesting! Thanks for sharing. “In the Cornell process, researchers take apart used cells and place the electrodes in an electrochemical bath containing 1,3-dimethyl-2-imidazolidinone, or DMI. The treatment removes the thicker SEI layer without destroying the electrode itself. The renewed electrodes can then be used to build new battery cells. The researchers reported that regenerated cells recovered up to 95% of their original capacity.“
