摘　　要：全钒液流电池(VFB)作为大容量、快速充放电、高效率的液流储能电池,是满足风能、太阳能发电及智能电网对大规模储能需求的一种理想储能装置。作为VFB的关键功能材料之一,离子传导膜既起到分隔正负极、防止电池短路的作用,又具备电荷载体的传导功能。介绍了VFB的工作原理及商业化离子传导膜的研究应用现状,对比分析了非氟离子传导膜实现电荷载体传导功能的改性方法,为新型离子传导膜的设计提供科学基础。As one kind of electrochemical energy storage techniques,vanadium flow battery(VFB)becomes one of the ideal candidates for large scale energy storage,such as wind power,solar power and smart grid,due to its features like flexible design,high efficiency and long cycle life.As a key part of VFB cell,a membrane is employed to separate electrolytes(vanadium ions),while still transfer protons to complete the current circuit.The research and application progresses of VFB working principle and commercial ion-exchange membranes were reviewed.And the ways of charge carrier conduction function of non-fluorine ion-conducting membrane were compared,which may provide scientific foundation for the design of high performance membrane.
