摘　　要：我国镁资源的高自然丰度,以及对高能量密度和安全储能设备的需求激发了人们对可充镁电池(RMB)的研究兴趣.然而,在充放电过程中,镁金属负极表面钝化层的形成、金属镁的不均匀沉积以及金属镁与常规电解质的相容性差等严重影响了镁电池的性能.镁金属负极与电解液界面的稳定性在很大程度上决定了电池循环稳定性和库伦效率.本文概述了近年来镁二次电池界面失效机制的研究进展,并总结了构建高导离子而电子绝缘的电极/电解质界面策略.最后,展望了稳定镁负极/电解液界面和实现高性能镁二次电池的未来发展方向.The high natural abundance of magnesium resources in China,and the demand for high energy density and safe energy storage devices have stimulated research interest in rechargeable magnesium batteries(RMB).However,during the charge-discharge cycle,the formation of passivation layer,the uneven deposition on the magnesium metal anode surface,and the poor compatibility of magnesium metal with conventional electrolytes seriously affect the performance of RMB.The stability of the Mg anode-electrolyte interphase largely determines the cycle stability and Coulombic efficiency of the battery.This review outlines the research progress on the interfacial failure mechanism of RMB in recent years,and summarizes the strategies for constructing electrode/electrolyte interphase that is highly conductive to ions but electrically insulating.Finally,the future development direction of stabilizing magnesium anodes for realizing high-performance magnesium secondary batteries is envisioned.
