Metallic zinc holds promise as a cost-effective and scalable material for secondary energy storage applications. However, its inherent reversibility issues hinder its practical implementation. Among various strategies, interface engineering has emerged as a promising approach to enhance the reversibility of zinc anodes. Herein we introduce an innovative method involving the parallel deposition of poly(acrylic acid) (PAA) and zinc metal, creating a composite layer of polymer and zinc, denoted as Zn-PAA. This unique Zn-PAA layer deposition technique remarkably enhances interfacial behavior, ensuring superior cyclic stability in symmetric cells. Moreover, the Zn-PAA layer reduces polarization effects and effectively mitigates interface alterations during plating and stripping processes resulting in increased interface stability. This study highlights the potential of simultaneous electropolymerisation and zinc deposition as a promising strategy to coat and densify interface on zinc anode with intertangled matrix of zinc and polymer for improving the performance and stability of zinc anodes in batteries.

基于聚合物的钝化层可在水性电解质中稳定锌阳极
金属锌有望成为二次能源存储应用中具有成本效益且可扩展的材料。然而,其固有的可逆性问题阻碍了其实际实施。在各种策略中,界面工程已成为增强锌阳极可逆性的一种有前途的方法。在此,我们介绍了一种创新方法,涉及聚丙烯酸(PAA)和锌金属的平行沉积,形成聚合物和锌的复合层,表示为Zn-PAA。这种独特的 Zn-PAA 层沉积技术显着增强了界面行为,确保对称电池具有卓越的循环稳定性。此外,Zn-PAA 层可减少极化效应,有效减轻电镀和剥离过程中的界面变化,从而提高界面稳定性。这项研究强调了同时电聚合和锌沉积作为一种有前途的策略的潜力,用锌和聚合物的交织基质涂覆和致密化锌阳极上的界面,以提高电池中锌阳极的性能和稳定性。
