Aqueous zinc ion batteries (AZIBs) offer great potential for large-scale energy storage because of their high safety, low cost and acceptable energy density. However, the cycle life of AZIBs is inevitably affected by parasitic reactions and dendritic growth caused by multiple factors such as electrode, electrolyte and separator, which pose significant obstacles to the practical application of AZIBs. To address these challenges, conducting polymer (CP) based materials have gained widespread attention in the realm of rechargeable batteries due to the adjustable band gap, controllable morphology, and excellent flexibility of CPs. In particular, CPs exhibit remarkable conductivity, low dimensionality, and doping characteristics, making them highly promising for integration into the AZIB system. In this review, the problems associated with the cathode, anode, electrolyte, and separator of AZIBs are discussed, and the application of CPs for their modification is summarized. The review provides a comprehensive analysis of the action mechanisms involved in the CP modification process and offers valuable insights for the design and development of CPs that can be effectively utilized in AZIBs. Additionally, the review presents a promising outlook of this research field, aiming to further advance the application of low-cost and high-performance CPs and their composites in AZIBs.
水系锌离子电池（AZIBs）因其高安全性、低成本和可接受的能量密度，在大规模储能方面具有巨大潜力。然而，AZIBs的循环寿命不可避免地受到电极、电解质和隔膜等多种因素引起的寄生反应和枝晶生长的影响，这对AZIBs的实际应用构成了重大障碍。为应对这些挑战，基于导电聚合物（CP）的材料因其可调节的带隙、可控的形态和优异的柔韧性，在可充电电池领域受到了广泛关注。特别是，CPs具有显著的导电性、低维度性和掺杂特性，使其在集成到AZIB系统中具有很大潜力。在这篇综述中，讨论了与AZIBs的阴极、阳极、电解质和隔膜相关的问题，并总结了CPs在其改性方面的应用。该综述对CP改性过程中涉及的作用机制进行了全面分析，并为可有效应用于AZIBs的CPs的设计和开发提供了有价值的见解。此外，该综述展示了这一研究领域的广阔前景，旨在进一步推动低成本、高性能CPs及其复合材料在AZIBs中的应用。
