| 摘 要： | 可充电镁电池具有理论体积比容量大、 地壳丰度高、 成本低、 环境友好及更为安全等优点, 是未来高能量存储系统发展的重要方向之一. 在大多数传统电解液中, 镁金属负极表面形成的钝化膜会阻碍镁的可逆沉积溶解过程, 从而限制了可充电镁电池的商业化应用. 由于存在成本高、 合成步骤复杂、 离子电导率低及难以同时与正负极兼容等问题, 聚焦于解决镁负级钝化问题的电解液研究陷入瓶颈. 因此, 通过对镁电池负极进行修饰改性, 使其在传统电解液中实现可逆过程是一种具有发展前景的策略. 本文从合金负极及人工界面形成两方面总结了近年来用于可充电镁电池负极改性的策略, 并在分析对比的基础上提出了进一步发展的结论和展望.

| Abstract: | Rechargeable magnesium batteries（RMBs） are a promising candidate for the development of high-energy storage systems due to its superiorities of relatively high theoretical volumetric capacity， high crustal abundance， low cost， especially environmental friendliness and safety. It is worth noting that the formation of a passivation film on the surface of magnesium（Mg） anode in most conventional electrolytes is an enormous obstacle， which leads to irreversible deposition/stripping behavior of Mg and thus limits the implementation of commercial RMBs. Researches focusing on electrolytes to tackle the obstacle have been in the bottleneck due to the restrictions of expensive price， complex synthesize process， low ionic conductivity， poor compatibility with cathodes and anodes simultaneously， etc. Facilitating modification of anode coming back to conventional electrolytes in RMBs is an alternatively promising avenue. This review summarizes recent studies concerning anode modification including alloy anode materials and formation of artificial interphase. Based on the analysis and comparison of previous researches， we propose conclusion and perspective for further development of RMBs. |
