Electrode restoration tech emerges that recovers up to 95 percent of used lithium-ion battery capacity

A technology has been developed to restore the performance of electrodes from used lithium-ion batteries without dismantling or melting them. Researchers expect the method can recover up to 95 percent of battery capacity and more than halve manufacturing costs for refurbished batteries. The approach regenerates electrodes directly on their metal current collectors by removing the SEI layer using a DMI solvent and applying a recovery process. It was tested mainly on EV batteries with 70 to 80 percent state of health.
