AlCl₃-dissolved Diglyme as Electrolyte for Room-Temperature Aluminum Electrodeposition

Abstract

We first report an AlCl₃-containing diglyme electrolyte for room temperature Al electrodeposition, which have relatively low volatilities and low cost. With the molar ratio of AlCl₃:diglyme = 1:5, the diglyme solution enabled deposition and dissolution of Al, which required relatively small overpotentials at room temperature. The deposits were not dendritic, indicating potential applications for Al plating or Al ion batteries.
