The energy storage technology of liquid flow has the characteristics of high safety,high efficiency,long life,and environmental friendly.It is suitable for large-scale energy storage and distributed energy storage.Ion conducting membrane is one of key materials of a flow battery,upon which the properties and cost of ion conducting membranes directly affect the performance and cost of flow batteries.Among various ion conducting membranes,the compositions and structures of the selective layers and porous supporting layers of composite ion conducting membranes can be adjusted independently.Thus,composite membranes can exhibit high selectivity,high conductivity and high stability at the same time,which have been widely investigated and utilized in flow batteries.Moreover,by tuning the structures of the selective layers of composite membranes,their selectivity and conductivity can be further optimized,then improving the performance and lifespan of flow batteries.Therefore,this review will summarize the structure adjustment strategies of the selective layers of porous composite membranes based on their research progress in flow batteries,providing the theoretical instructions for the further development of ion conducting membranes in flow batteries.
