摘要：

通过电解液分解在电极上形成的固体电解质界面（SEI）层被认为是影响电池性能的最重要因素。 然而，我们发现金属离子溶剂化结构也会影响其电极性能，尤其可以阐明许多SEI无法解释的实验现象。基于该综述，本文总结了金属离子溶剂化结构和衍生的金属离子去溶剂化行为的重要性，并建立了相应的界面模型以展示界面行为和电极性能之间的关系，并将其应用于不同的电极和电池体系。我们强调了电极界面离子/分子相互作用对电极性能的影响，该解释与以往基于SEI的解释不同。该综述为理解电池性能和指导电解液设计提供了一个新的视角。

Abstract:

Solid-electrolyte interphase (SEI) layer formed on the electrode by electrolyte decomposition has been considered to be one of the most important factors affecting the battery performance. We discover that the metal ion solvation structure can also influence the performance, particularly, it can elucidate many phenomena that the SEI cannot. In this review, we summarize the importance of the metal ion solvation structure and the derived metal ion de-solvation behaviors, by which we can build an interfacial model to show the relationship between the interfacial behavior and electrode performance, and then apply to different electrode and battery systems. We emphasize the influences of ionic and molecular interactions on electrode surface that differ from previous SEI-based interpretations. This review provides a new view angle to understand the battery performance and guide the electrolyte design.

Key words: battery, electrolyte, solvation structure, electrode interfacial model, solid electrolyte interphase layer
