A novel amphoteric ion exchange membrane (AIEM) was successfully prepared by one-step radiation grafting of sodium styrene sulfonate (SSS) and dimethylaminoethyl methacrylate (DMAEMA) onto ethylene-vinylalcohol copolymer (EVOH) powder and sequent transferring into film by casting method. Fourier transform infrared spectrometry (FT-IR), thermal gravimetric analyzer (TGA) and elemental analysis testified SSS and DMAEMA were successfully grafted onto EVOH. The ion exchange capacity, water uptake and proton conductivity of the resulting AIEM increased with grafting yield (GY). At the GY of 40.9%, the permeability of vanadium ions of AIEM was 3.98 × 10−7 cm2 min−1, which was better than Nafion117 membrane. Furthermore, the cost of this AIEM is much lower than that of Nafion117 membrane. This work provided a low cost and simple method for fabrication of the ion exchange membrane for vanadium redox flow battery (VRFB). Meanwhile, it also provided a new direction for the application of EVOH.

A new kind of composite membrane consisting of sulfonated poly(ether sulfone) (SPES), poly(vinylidene fluoride) (PVDF), and phosphotungstic acid (TPA) has been prepared and employed as the ion-exchange membrane for vanadium redox flow battery (VRB) application. The addition of the highly crystalline and hydrophobic PVDF effectively confines the swelling behavior of SPES/PVDF/TPA. The composite membrane exhibits one order of magnitude lower vanadium ions permeability and much better single cell performance compared to pristine SPES and Nafion 115 membranes. The single cell with SPES/PVDF/TPA membrane shows much lower capacity loss, higher coulombic efficiency (>97%), and higher energy efficiency (>82%) than which with Nafion 115 membrane. In the self-discharge test, single cell with SPES/PVDF/TPA membrane shows much longer duration in the open-circuit voltage decay than which with Nafion 115 membrane. With all the good performances and low cost, the SPES/PVDF/TPA membrane is expected to have excellent commercial prospects as ion-exchange membrane for VRB system.
