Magnesium (Mg) batteries are a promising next-generation power source, due to attractive properties such as double charges of divalent Mg2+ ions, high volumetric capacity (3,832 mAh cm−3), which is almost twice compared to that of Li batteries, and the low price of Mg metal. However, the formation of ion-insulating interphase on the surface of Mg metal in common organic electrolytes impedes transports of multivalent ions, which has been a problematic issue for Mg metal batteries. Herein, to address this issue, we propose two different strategies; (1) chemical tuning of the interphase into Mg2+-conductive film and (2) the use of magnesiophilic scaffold as an anode substrate. Our studies will offer a new insight to understand the role of interphase and provide a guideline to design a better interphase for reversible Mg metal batteries.
