A method is provided to fabricate a Nafion separating membrane for achieving low impedance and low permeability. Sodium 4-styrenesulfonate (NASS) is grafted to the surface of the membrane through an oxygen plasma induced grafting technique. A modified Nafion-g-NASS membrane is thus fabricated for a vanadium redox flow battery (VRFB) with the permeability of vanadium ions reduced and the conductivity of protons improved. The modified membrane shows higher ion exchange capacity and permeating conductivity along with enhanced voltage efficiency (VE), coulombic efficiency (CE) and energy efficiency (EE). Due to the low permeability of vanadium ions, the VRFB with the modified membrane shows slower self-discharge than that with the pristine Nafion membrane. After 200 cycles of charging and discharging, the VE, CE and EE remain stable. In particular, the modified VRFB shows a higher rate of capacity retention than the pristine VRFB.
