The thermal stability window of current commercial carbonate-based electrolytes is no longer sufficient to meet the ever-increasing cathode working voltage requirements of high energy density lithium-ion batteries. It is crucial to construct a robust cathode–electrolyte interphase (CEI) for high-voltage cathode electrodes to separate the electrolytes from the active cathode materials and thereby suppress the side reactions. Herein, this review presents a brief historic evolution of the mechanism of CEI formation and compositions, the state-of-art characterizations and modeling associated with CEI, and how to construct robust CEI from a practical electrolyte design perspective. The focus on electrolyte design is categorized into three parts: CEI-forming additives, anti-oxidation solvents, and lithium salts. Moreover, practical considerations for electrolyte design applications are proposed. This review will shed light on the future electrolyte design which enables aggressive high-voltage cathodes.

目前商用碳酸盐基电解质的热稳定窗口已不足以满足高能量密度锂离子电池不断提高的阴极工作电压要求。为高压阴极电极构建坚固的阴极电解质界面（CEI）以将电解质与活性阴极材料分离从而抑制副反应至关重要。在此，这篇综述简要介绍了 CEI 形成和组成机制的历史演变、与 CEI 相关的最新表征和建模，以及如何从实际电解质设计的角度构建稳健的 CEI。电解质设计的重点分为三个部分：CEI 形成添加剂、抗氧化溶剂和锂盐。而且，提出了电解质设计应用的实际考虑因素。这篇综述将阐明未来的电解质设计，它可以实现侵蚀性高压阴极。
