High-safety and low-cost aqueous zinc ion batteries (AZIB) are expected to be used in large-scale energy storage systems. However, currently used zinc (Zn) anode materials are susceptible to derogatory processes such as dendrite growth or cause side reactions which limits their practical applications. Although polymeric materials have been specifically applied for Zn anode protection, the complicated composition and lack of understanding of the working mechanisms of currently used materials are not conducive to guiding further research. This review provides a summary and discussion of polymer materials that are used in AZIB applications and a platform for future material development. The importance of polymer materials and the advantages of their applications in Zn batteries are described. Subsequently, the latest progress in the design and optimization of polymer for stable Zn anodes is summarized from multiple perspectives, including electrolyte additives, artificial protective layers, hydrogel electrolytes, and novel separators. Finally, the future challenges and research directions of polymer-stabilized Zn anode are proposed.
