固体电解质中间相（SEI）是在所有电化学电池中的显式和隐式界面处通过电化学还原和化学反应的组合形成的化学上不同的材料相。在过去的十年中，积累在这种界面材料相中的材料的结构、化学和热力学已经出现，在二次电池中实现高水平的阳极可逆性方面发挥关键作用，特别是在电化学活性金属用作高能量密度和成本效益存储的阳极的系统中。在这里，我们回顾了历史，化学，形成特点，并采取措施，以实现合理的设计，在金属阳极的SEI。明确利用电解质组分的氧化还原化学来构建电化学电池内设计的有利SEI的策略，以及那些从电池外执行的situochemistry中受益的策略，以创建增强阳极可逆性的人工SEI。以这些方法为出发点的基础上取得的进展，审查还考虑相间的设计规则，促进化学，机械和电化学稳定性和快速离子运输通过SEI。最后，我们讨论了在单价（Li，Na和K），二价（Mg，Ca和Zn）和三价（Al）金属上形成的SEI的差异和相似性，以开发具有成本效益但高性能的阳极，并在此基础上，强调迫切需要侵入性实验工具来分析金属原子水平上的SEI。
The solid electrolyte interphase (SEI) is a chemically distinct material phase formed by a combination of electrochemical reduction and chemical reactions at both the explicit and implicit interfaces in all electrochemical cells. The structure, chemistry, and thermodynamics of the materials that accumulate in such interfacial material phases have emerged over the last decade to play crucial roles in achieving high levels of anode reversibility in secondary batteries, especially in systems where electrochemically active metals are used as anodes for high-energy-density and cost-effective storage. Here, we review the history, chemistry, formation characteristics, and approaches taken to achieve rational design of the SEI at metal anodes. Strategies that explicitly take advantage of the redox chemistry of electrolyte components to build designed, favourable SEI inside electrochemical cells, as well as those that benefit fromex situchemistries performed outside the cell to create artificial SEI that enhance anode reversibility are highlighted. Taking advances based on these methods as a point of departure, the review also considers interphase design rules that facilitate chemical, mechanical, and electrochemical stability and fast ion transport through the SEI. Finally, we discuss differences and similarities of SEI formed on monovalent (Li, Na, and K), divalent (Mg, Ca, and Zn), and trivalent (Al) metals of contemporary interest for developing cost-effective but high-performance anodes and on that basis, underscore the urgent need for intrusive experimental tools for analyzing the SEI on metals at atomic levels.
