This work develops a deep eutectic solvent (DES)-functionalized activated carbon as a selective adsorbent for recovering lithium from complex solutions generated during lithium-ion battery recycling. The material demonstrates high lithium selectivity over transition metals, excellent reusability, and effective performance in real leachates from spent NMC cathodes.
This approach offers an efficient and sustainable strategy for lithium recovery, contributing to more resource-efficient battery recycling, reduced reliance on primary raw materials, and the advancement of a circular battery economy.
