Metal-ion batteries (MIBs) are promising for large-scale energy storage because they can alleviate the inherent intermittency of renewable energy. As an indispensable part of MIBs, electrolytes influence the electrochemical performance. Recently, the new concept of eutectic electrolytes has aroused extensive research attention in the field of MIBs due to their simple synthesis and eco-friendly features. Nevertheless, the development of eutectic electrolytes is still in its infancy and deserves further attention. This review focuses on the systematic understanding of the relationship between eutectic electrolytes and the corresponding performances of MIBs. First, fundamentals of eutectic electrolytes are described. Then, recent progress in the use of eutectic electrolytes in MIBs is introduced, including the correlations between structure and properties, the chemistry at the electrode interface, and the ion/charge transport mechanism. Finally, the challenges and prospects related to eutectic electrolytes are discussed. This Focus Review will provide better directions to devise advanced eutectic electrolytes for high-performance MIBs.

先进金属离子电池中的共晶电解质

金属离子电池（MIB）有望用于大规模储能，因为它们可以缓解可再生能源固有的间歇性。作为 MIB 不可或缺的组成部分，电解质会影响电化学性能。近来，共晶电解质的新概念因其合成简单、环保等特点引起了 MIBs 领域的广泛研究关注。尽管如此，共晶电解质的发展仍处于起步阶段，值得进一步关注。本综述着重于系统理解共晶电解质与 MIB 的相应性能之间的关系。首先，描述了共晶电解质的基本原理。然后，介绍了在 MIB 中使用共晶电解质的最新进展，包括结构和性质之间的相关性、电极界面的化学性质以及离子/电荷传输机制。最后，讨论了与共晶电解质相关的挑战和前景。本次重点回顾将为设计用于高性能 MIB 的先进共晶电解质提供更好的方向。
