Rechargeable lithium metal batteries (LMBs) have attracted wide attention for future electric vehicles and next‐generation energy storage because of their exceptionally high specific energy density. Recently, the development of electrode materials for LMBs has been extensively discussed and reviewed in the literature, but there have been very few reports that systematically review the status and progress of electrolytes for such applications. Actually, the viability of practical LMBs critically depends on the development of suitable liquid electrolytes due to the high reactivity of Li metals toward most solvents. This paper provides a systematic summary of the background and recent advances of the electrolytes for LMBs with an emphasis on the thermodynamic and kinetic stabilities at the interfaces. In addition, the emerging advanced characterization techniques for understanding the electrolyte–electrode interfaces are surveyed. Finally, a perspective for future directions is provided.

用于可充电锂金属电池的高级液体电解质

可充电锂金属电池（LMB）由于其特别高的比能量密度，已引起了未来电动汽车和下一代能量存储的广泛关注。近来，在文献中已经广泛地讨论和评论了用于LMB的电极材料的开发，但是很少有报道系统地回顾了用于此类应用的电解质的状态和进展。实际上，由于Li金属对大多数溶剂的高反应性，实际LMB的生存能力在很大程度上取决于合适的液体电解质的发展。本文提供了LMBs电解质的背景和最新进展的系统总结，重点是界面处的热力学和动力学稳定性。此外，为了理解电解质-电极的界面，对新兴的先进表征技术进行了调查。最后，提供了未来方向的观点。
