Abstract

Abstract: The demand for high‐energy‐density and safe energy storage devices has spurred increasing interest in high‐voltage rechargeable magnesium batteries (RMB). As electrolytes are the bridge connecting the cathode and anode materials, the development of high‐voltage electrolytes is the key factor in realizing high‐voltage RMBs. This concept presents an overview of three chloride‐free electrolyte systems with wide electrochemical windows, together with the degradation mechanisms and modification strategies at the anode/electrolyte interphase. Finally, future directions in stabilizing Mg anodes and realizing high‐voltage RMBs are highlighted. Abstract : A little light on electrolytes : We take a timely and comprehensive look at the criteria for high‐voltage magnesium metal batteries (RMBs) from the viewpoint of high‐voltage chloride‐free electrolytes and the corresponding electrolyte/anode interphase. Potential high‐voltage chloride‐free electrolytes and the corresponding interphase degradation mechanisms are analyzed in depth.
