摘　　要：围绕锌负极在中性电解质中腐蚀产生枝晶、钝化、析氢等关键问题,综述了锌负极缓蚀剂防护方法的研究进展,旨在从溶剂化结构调控、静电屏蔽、吸附作用、原位固态电解质界面4种防护机理,揭示不同类型缓蚀剂的性能、稳定性及实际应用的可行性,进而为锌负极保护提供依据,展望缓蚀剂防护方法未来的发展方向。Aqueous Zn-ion batteries are considered as possible substitutes for Li-ion batteries because of their low cost,high safety and environment-friendly.However,the hydrogen evolution side reaction,passivation and dendrite of Zn anode in neutral water electrolyte seriously affect the stability and safety of the battery and hinder its application.Zn anode is the key part that affects the capacity,stability and cycle life of battery.Introduction of corrosion inhibitor into electrolyte is a simple and practical method to inhibit the corrosion of Zn electrode.In this review,the mechanisms related with dendrite formation,passivation and hydrogen evolution reaction of Zn anode in neutral electrolyte are introduced first,and then the countermeasures of using corrosion inhibitor to solve these three problems are summarized.The performance,stability and feasibility of practical application of various corrosion inhibitors for the protection of Zn anode are illustrated in terms of perspectives such as the adjustment of solvation structure,electrostatic shield,adsorption,and in-situ solid electrolyte interface etc.Finally,the future development direction of corrosion inhibitor-based protection method for Zn anode is also proposed.
