Lithium metal batteries (LMBs) bring a bright future for the industrialization with higher voltage and energy density than conventional lithium ion batteries (LIBs) as lithium metal offers an ultra‐high specific capacity and the lowest electrochemical potential. However, they tend to confront unstable interface with electrolytes, uncontrollable dendrite growth and notorious safety concerns, seriously blocking the practical application of lithium metal anodes. Electrolyte is always considered as the most critical factor, directly affecting the overall battery behavior. In this case, the rearrangement of active components or designing novel electrolytes become indispensable approaches and tremendous efforts are required to seek for positive solutions. Herein, we provide recent advancements in prevailing liquid, solid and gel electrolytes from the perspective of their potential application in LMBs. The key scientific issues related to enhanced performance have also been highlighted.

锂金属电池电解液设计的最新进展

锂金属电池（LMB）具有比传统锂离子电池（LIB）更高的电压和能量密度，为工业化带来了光明的未来，因为锂金属具有超高的比容量和最低的电化学势。然而，它们倾向于面对与电解质的不稳定界面，不可控的枝晶生长以及臭名昭著的安全性问题，严重地阻碍了锂金属阳极的实际应用。电解液始终被认为是最关键的因素，直接影响电池的整体性能。在这种情况下，活性成分的重新排列或设计新颖的电解质成为必不可少的方法，并且需要大量的努力来寻求积极的解决方案。在此，我们提供了当前盛行的液体的最新进展，从其在LMB中的潜在应用的角度来看，固体和凝胶电解质。还强调了与提高性能有关的关键科学问题。
