With the increasing use of Li-ion batteries, Li extraction from brine and seawater, as well as recovery from used Li-ion batteries have become a necessary step for achieving sustainability. Kazuya Sasaki and colleagues report a three-electrode dual-power-supply electrochemical pumping system for recovering high-purity Li from ionic solutions with much higher energy efficiency than the conventional approaches.
