摘　　要：以高体积能量密度、高理论容量、低还原电位和高丰度的锌为负极的水系锌离子电池,由于其安全环保引起了越来越多的关注,但锌阳极与电解液界面容易产生锌枝晶沉积,和游离水/氧引起的相关副反应[析氢反应(HER)、腐蚀和钝化],以及阴极的体积膨胀和活性物质的溶解等阻碍了锌离子电池的商业应用。聚合物具有优越化学稳定性、可调结构、高能量密度、优异的力学性能和结构柔韧性,在锌离子电池中有着巨大的应用前景。本文综述了近来聚合物在锌离子电池中的应用,总结了其在优化电极、隔膜、电解质和界面方面的研究进展,以期为研究基于聚合物提升锌离子电池的性能提供参考。Water zinc-ion batteries with high volume energy density,high theoretical capacity,low reduction potential and high abundance zinc as anode have attracted more and more attention due to their safety and environmental protection.However,the interface between zinc anode and electrolyte is prone to produce zinc-dendrite deposition.Besides,the related side reactions caused by free water/oxygen[hydrogen evolution reaction(HER),corrosion and passivation],the volume expansion of the cathode,and the dissolution of the active substance hinder the commercial applications of zinc-ion batteries.Polymers with excellent chemical stability,adjustable structures,high energy density,excellent mechanical properties,and structural flexibility have great application prospects in zinc-ion batteries.In this paper,the recent polymer applications in zinc-ion batteries were reviewed,and the research progresses in optimizing the electrode,separator,electrolyte and interface were summarized,providing references for improving the performances of polymer-based zinc-ion batteries.
