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.
