[Display omitted] •The functionality and design principles of artificial interfacial layers are discussed.•The role of artificial interface layer structure in guiding Zn2+ transport is introduced.•The challenges and future development directions of interface engineering are proposed. Aqueous zinc-ion batteries (AZIBs) have received widespread attention because of their intrinsic merits, such as excellent safety, and environmental benignity. However, the Zn anode inevitably suffers from the hydrogen evolution on zinc, corrosion, dendrite growth, and surface passivation in AZIBs, which seriously deteriorates the electrochemical performance of AZIBs. The interface artificial interface engineering on the surface of zinc have been considered as one of the most effective strategies to resolve the above-mentioned issues. In this review, we offer a comprehensive summary of the challenges and optimization strategies faced by zinc anodes. In addition, we also conducted a comprehensive and in-depth analysis of these interfacial layer protection strategies, focusing on protective mechanisms behind the optimization strategies and the promotion of full battery. At last, the challenges and future development directions of interface engineering in the design of stable zinc anodes for high-performance AZIBs were proposed. This review can offer potential directions for the rational construction of stable Zn anode employed in AZIBs.
