抄録

The electrodeposition of Mg metal from an ionic liquid–glyme mixture was investigated at room temperature. The mixture contains a glyme, a simple amide salt Mg(Tf[2]N)[2] (Tf = SO[2]CF[3]), and a quaternary-ammonium Tf2N ionic liquid. Using the mixture bath, substantial cathodic electrodeposition of Mg at a large current density (∼10 mA cm[−2]) was observed, suggesting a change in coordination geometry around Mg[2+] cation together with improved conductivity. By mixing diglyme, the conductivity increased by an order of magnitude (2.5 – 2.6 mS cm[−1]) compared to the glyme-free ionic liquid (0.35 mS cm[−1]) and the viscosity became as low as that of pure glyme. Additionally, potentiostatic electrolysis resulted in a non-dendritic thin film of elemental Mg with metallic luster.
