Preparation of bcc Mg-Li-Al-Zn Alloy by Electrolysis in Molten Salt LiCl-KCl and the Alloy’s Electrochemical Performance as Anode Material for Magnesium Batteries

Abstract

Electrolysis was conducted in a molten salt containing LiCl and KCl at 500°C for bcc Mg-11.9 wt.% Li-8.5 wt.% Al-0.57 wt.% Zn alloy fabrication. As-rolled Mg-11.9 wt.% Li-8.5 wt.% Al-0.57 wt.% Zn and Mg-2.6 wt.% Al-0.72 wt.% Zn foils were assembled into separate Mg/2 mol kg⁻¹ MgCl₂/Cu cells. Mg-11.9 wt.% Li-8.5 wt.% Al-0.57 wt.% Zn foil as anode exhibited higher discharge voltage and capacity than Mg-2.6 wt.% Al-0.72 wt.% Zn foil did in the cell.
