▎ 摘  要

For the modification of reversibility of magnesium deposition-dissolution in non-aqueous glyme-based electrolytes, the surface of a magnesium metal or magnesium alloy AZ31 was covered by graphene oxide modified using Grignard reagent. After modification, the magnesium chloride moieties appeared to connect with oxygen-containing functional groups of graphene oxide. The magnesium electrode covered with MgCl-modified graphene oxide exhibited a reversible redox reaction assigned to the deposition-dissolution of magnesium from the substance without overpotential in a conventional magnesium salt - glyme solution. The MgCl-modified graphene oxide-covered magnesium alloy electrode was compatible with two-electrode test cells with Mo6S8 positive electrode. (c) The Author(s) 2020. Published by ECSJ.
