摘　　要：离子交换膜是水系有机液流电池的核心部件,其对离子的快速、选择性传导是水系有机液流电池实现高能量效率、低容量衰减速率的关键.而离子的传导过程与膜内的微观结构密切相关,因此本文结合膜内离子传导通道的构筑策略分析,综述微相分离膜、自具微孔膜、微孔框架膜在水系有机液流电池中的发展;并围绕离子交换膜的离子传导性、电活性分子阻隔性、稳定性和兼容性等重要特性,探讨离子交换膜设计及优化方向,以期为水系有机液流电池专用离子交换膜的创制提供参考.Ion-exchange membranes are a crucial component of aqueous organic redox flow batteries(AORFBs),and their fast and selective ion conduction is the key to achieve high energy efficiency and low capacity fade rate of AORFBs.As the ion conduction process is closely related to the microstructure in membranes,we review herein the development of membranes in AORFBs,including membranes with microphase-separated structures,membranes from polymers of intrinsic microporosity,and microporous framework membranes,combining with the analysis of the construction strategies of ion channels.Moreover,the design and optimization direction of ion-exchange membranes are discussed based on their critical features,such as ion conductivity,permeability of redox-active molecules,stability,and compatibility,in order to present constructive suggestions and opinions for the creation of appropriate membranes for AORFBs.
