Li procurement is becoming a matter of importance worldwide, because theuse of Li-ion batteries in electric vehicles will be increased. I proposedmethod for Li recovery from seawater. The method involves the use of an ionicliquid through which only the Li ions in seawater and not the other ions,including Na, Mg, Ca and K, permeate from the anode side to the cathode sideduring electrodialysis. Furthermore, it should be suitable for the recycling ofused Li-ion batteries.
