Mg batteries are a promising battery technology that could lead to safer and significantly less expensive non‐aqueous batteries with energy densities comparable or even better than state‐of‐the‐art Li‐ion batteries. Although the first prototype Mg battery using stable Mo 6 S 8 as cathode was introduced over fifteen years ago, major challenges remain to be solved. In particular, the design of high energy cathode materials and the development of non‐corrosive electrolytes with high oxidative stability are issues that need to be tackled. Herein, we present a new, general, and robust approach towards achieving stable cycling of Mg batteries. The core of our approach is the use of stable polymer cathode and Mg powder anode coupled with non‐nucleophilic electrolytes. Our systems exhibit an excellent rate capability and significant improvement in electrochemical stability.
