Research Progress of Proton Exchange Membranes for Vanadium Flow Battery
As a high-efficiency large-scale energy storage system,vanadium flow battery(VFB)system can meet the large-scale energy storage demand in the field of new energy,showing a superior development prospect.Proton exchange membranes(PEMs)are the key component materials of VFB system,which directly affect the charge and discharge performances,service life and cost of VFB system.It is particularly important to develop high performance PEMs with good proton conductivity,vanadium resistance and low price.Based on the materials and preparation methods of PEMs,this article classifies and summarizes the research progress of proton exchange membranes for VFB in recent years,and further elaborates the future research focus and development direction of proton exchange membranes.
