Wider exploitation of LIB energy storage technologies creates an alarming situation, especially for the resource management of critical metals and the environment. In this work, we report the direct regeneration of a spent lithium cobalt oxide (LCO) cathode material.
After electrolysis, CoO/Co and Li 2 CO 3 were leached out from the molten salts in water, and the recovery rates of Li and Co were high up to 85% and 99%, respectively.
