Problems of zinc anode including dendrite and hydrogen evolution seriously degrade the performance of zinc batteries. Solid electrolyte interphase (SEI), which plays a key role in achieving high reversibility of lithium anode in aprotic organic solvent, is also beneficial to performance improvement of zinc anode in aqueous electrolyte. However, various studies about interphase for zinc electrode is quite fragmented, and lack of deep understanding on root causes or general design rules for SEI construction. And water molecules with high reactivity brings serious challenge to the effective SEI construction. Here, we reviewed the brief development history of zinc batteries firstly, then summarized the approaches to construct SEI in aqueous electrolyte. Furthermore, the formation mechanisms behind approaches are systematically analyzed, together with discussion on the SEI components and evaluation on electrochemical performance of zinc anode with various types of SEI. Meanwhile, the challenge between lab and industrialization are also discussed.
锌负极的问题，包括枝晶和析氢，严重降低了锌电池的性能。固体电解质界面（SEI）在非质子有机溶剂中实现锂负极的高可逆性方面起着关键作用，对水性电解质中锌负极的性能提升也有益处。然而，关于锌电极界面的各种研究相当零散，并且对SEI构建的根本原因或通用设计规则缺乏深入理解。而具有高反应活性的水分子给有效的SEI构建带来了严峻挑战。在此，我们首先回顾了锌电池的简要发展历程，然后总结了在水性电解质中构建SEI的方法。此外，系统分析了这些方法背后的形成机制，同时讨论了SEI的成分以及对具有不同类型SEI的锌负极电化学性能的评估。与此同时，还讨论了实验室与工业化之间的挑战。
