Abstract:

Membrane with both high ion selectivity and conductivity is crucial to the new energy battery technologies (such as flow batteries, fuel cells, lithium batteries). In recent years, researchers have proposed to construct porous ion conductive membranes to break the trade-off effect between ion selectivity and ion conductivity. This review briefly summarizes the latest research progress of porous ion conductive membranes as battery membranes from three aspects of inorganic, organic and composite porous ion conductive membranes, and summarizes the advances of porous ion conductive membranes in new energy batteries such as flow batteries, fuel cells and lithium batteries. Finally, this review points out that the future research of porous ion conductive membranes should focus on the adjustment of porous membrane structure, the development of high-performance porous membrane materials, and the application of porous membranes in novel battery systems.
