可充镁电池镁铝氯络合物电解液的研究进展

Rechargeable magnesium metal batteries (RMBs) are widely regarded as one of the most promising next-generation energy storage technologies due to their high safety, low cost, and high volumetric energy density of metallic Mg. However, the performance of the electrolyte plays a decisive role on the overall electrochemical behavior of the battery. Magnesium-aluminum chloride complex (MACC) electrolytes have attracted attention owing to their exceptional interfacial stability and high coulombic efficiency. In recent years, the researchers adopted various strategies of refining coordination structures, optimizing component ratio and developing functional additives to pave the way for high stability and practicality of MACC electrolytes. This review outlines the synthesis method, active ingredients, electrochemical performance, the compatibility of cathode materials, and highlights their potential application and future development directions of magnesium batteries.
