水系锌离子电池(Aqueous Zinc Ion Batteries,AZIBs)作为近年来新兴的电化学储能装置,因其高能量密度、低成本以及高安全性,在众多金属离子电池中脱颖而出.然而不可避免的枝晶生长、析氢反应(HER)和钝化层生成等问题降低了锌负极的稳定性,成为AZIBs发展的瓶颈.其中隔膜作为电池中的重要部件,确保了电池的安全运行,在实际应用中,为克服玻璃纤维隔膜的本征问题,功能隔膜策略作为提高AZIBs性能的有效方法而受到欢迎.论文系统地总结了功能隔膜材料在AZIBs中的最新研究进展,重点关注改性隔膜材料的设计策略及机制探究.最后,介绍了当前功能隔膜材料发展的制约因素和未来潜力.
Recent advances in functionalized separators for aqueous zinc ion batteries
As an emerging energy storage device,aqueous zinc ion batteries(AZIBs)stand out among many metal ion batteries due to their high energy density,low cost,and high safety.However,the inevitable issues of dendrite growth,hydrogen evolution reaction(HER),and passivation layer generation reduce the stability of zinc anodes and become the bottleneck for the development of AZIBs.The separator ensures the safe operation of batteries as an im-portant component.To overcome the intrinsic problems of widely used glass fiber(GF)separators,the strategy of designing functionalized films has received extensive attention as an effective method to improve the electrochemical performance of aqueous zinc ion batteries.Herein,the review systematically summarizes the latest advances of func-tionalized separators in AZIBs,mainly focusing on the design strategies and mechanism investigation of raw and modified separator materials.In the end,the current challenge and future prospects of the functionalized separators for zinc ion batteries are presented.
