水系锌离子电池因其固有的高安全性、经济效益和环境友好性,被认为是大规模储能系统的候选者.然而,负极/电解液界面上发生的枝晶生长、析氢反应和界面钝化等问题使其实际应用受到严重的阻碍.因此,构建稳定的负极/电解液界面在调节锌沉积和提高水系锌离子电池循环寿命等方面发挥着关键作用.基于对负极/电解液界面基础理论的研究,讨论了锌金属负极受制于不稳定界面而面临的诸多挑战,并系统总结了利用电解质工程稳定负极/电解液界面的调控策略.此外,介绍了包括分析锌金属负极的界面化学和表面形貌演变在内的有效性测试技术.最后,对未来研究提出建议和展望.这对构建高性能水系锌离子电池具有一定的借鉴意义.
Electrolyte engineering for optimizing anode/electrolyte interface towards superior aqueous zinc-ion batteries:A review
Aqueous zinc-ion batteries(AZIBs)are promising candidates for the large-scale energy storage systems due to their high intrinsic safety,cost-effectiveness and environmental friendliness.However,issues such as dendrite growth,hydrogen evolution reaction,and interfacial passivation occurring at the anode/electrolyte interface(AEI)have hindered their practical application.Constructing a stable AEI plays a key role in regulating zinc deposition and improving the cycle life of AZIBs.The fundamentals of AEI and the challenges faced by the Zn anode due to unstable interfaces are discussed.A comprehensive summary of electrolyte regulation strategies by electrolyte engineering to achieve a stable Zn anode is provided.The effectiveness evaluation techniques for stable AEI are also analyzed,including the interfacial chemistry and surface morphology evolution of the Zn anode.Finally,suggestions and perspectives for future research are offered about enabling a durable and stable AEI via electrolyte engineering,which may pave the way for developing high-performance AZIBs.
