Progress on Electrodeposition of Rare Earth Metals and Their Alloys

The electrodeposition of rare earth metals and their functional alloys has attracted widespread attention in recent two decades. This paper briefly reviewed the research process of the electrodeposition of rare earth metals and their alloys in aqueous solutions, molten salts, organic solvents, and ionic liquids. In addition, the problems of electrodeposition of rare earth metals and their alloys in different systems were analyzed, and the research directions in future were prospected.
