Aqueous zinc-ion batteries are promising candidates for next-generation energy storage due to their cost-effectiveness, high capacity, and low redox potential. However, zinc metal anodes undergo chemical corrosion in aqueous electrolyte, which limits their further development. Therefore, it is significant to achieve highly stable zinc anodes for the practical application of zinc-ion batteries. In this review, various existing Zn anode issues are summarized and discussed in detail. Moreover, we propose comprehensive strategies for constructing stable Zn anodes. Finally, the optimistic perspective and research directions are elaborated for functional zinc anodes. This work provides new insights for the rational design of zinc metal anodes.
