A novel kind of effective vanadium ion-suppressed polysulfone-polyvinylpyrrolidone (PSF-PVP) membrane with high ion selectivity, superior stability and low cost is designed and constructed for vanadium redox flow batteries (VRFBs). The VRFB with the PSF-PVP-50 membrane exhibits impressive coulombic efficiency (98%) as well as energy efficiency (89%), and outstanding stability during the 2000 h continuous charge-discharge cycling test.
