Electrodeposition of Lithium in Nonaqueous Solutions and Molten Salts

In this paper, the method of electrodeposition of lithium both in nonaqueous solutions and molten salts was summarized, and the key problems existed were also carried out. More details for electrochemical deposition of lithium metal by ionic liquids including AlCl3-based, EMI-based, BF4--based, PF6--based, Tf2N--based, N(CN)2--based were discussed, and more works needed for lithium recovery by electrochemical method in the future was also pointed out.
