With the supply of lithium resources beginning to dwindle, rechargeable aqueous zinc-ion batteries (AZIBs) have attracted research interests as alternatives to lithium-ion batteries. Developing high-performance and cost-effective cathodes can promote the commercialisation process of AZIBs. Transition metal-based materials, including different phases of vanadium oxides, manganese oxides and Prussian blue analogues are promising candidates due to their reasonable crystal structures to host Zn-ions. However, they are suffering from the low electrical conductivity and structural instability. The modification of these materials by conductive polymers and the formation of composites are demonstrated as promising strategies to solve the problem and improve the cathode performance in AZIBs. In this mini review, we summarize representative advancements of conductive polymer composites as cathodes in AZIBs and provide an insight into their future research directions.

随着锂资源的供应开始减少，可充电水性锌离子电池（AZIBs）作为锂离子电池的替代品引起了研究兴趣。开发高性能且具有成本效益的正极可以促进 AZIBs 的商业化进程。过渡金属基材料，包括不同相的钒氧化物、锰氧化物和普鲁士蓝类似物由于其合理的晶体结构来容纳锌离子，因此是有希望的候选者。然而，它们的导电性低且结构不稳定。导电聚合物对这些材料的改性和复合材料的形成被证明是解决问题和改善 AZIB 阴极性能的有前途的策略。在这篇简短的评论中，我们总结了导电聚合物复合材料作为 AZIB 阴极的代表性进展，并提供了对其未来研究方向的见解。
