Owing to the advantages of low cost, high energy density, and environment friendly, aqueous zinc ion batteries (AZIBs) are considered as promising energy storage devices. Inevitable zinc dendrites, corrosion, passivation, and hydrogen evolution reactions of zinc anodes have seriously hampered the practical application of AZIBs. To address the above-mentioned issues, zinc anode alloying is proposed as an emerging modification strategy. Therefore, it is essential to systematically summarize the obtained research results on zinc alloying strategies and analyze new perspectives. Based on the presented studies on zinc alloying anode, different improvement mechanisms are described, such as an artificial interface alloy protective layer, an electrostatic shielding effect, heterogeneous seeds as zincophilic sites, vertical plane matching strategy, etc. According to the different synthesis methods and mechanisms of action, recent advances have been summarized. Finally, the potential development prospects for further upgrading the alloying of zinc anodes are presented.
