Abstract：

Vanadium redox flow battery (VRFB) has high intrinsic safety, capacity and power decoupling, and shows good application prospects in the field of large-scale energy storage. As a key component of VRFB, membranes have an important impact on battery performance. Existing membranes used for VRFB are either expensive or have poor ion conductivity. Therefore, it is of great significance to develop new low-cost and high-performance membrane materials. In this study, partially fluorinated adamantane-containing poly(aryl ether) was synthesized, and pyridine groups were further grafted and functionalized. After swelling-induced microphase separation, PyAPEF membranes were obtained. PyAPEF membrane showed low area resistance (0.13 Ω·cm2), low swelling ratio, and high mechanical strength (>46.42 MPa), which was better than Nafion 212 membrane (area resistance 0.13 Ω·cm2, mechanical strength 17.0 MPa). At a current density of 200 mA/cm2, the PyAPEF-140 membrane showed excellent energy efficiency (EE=84.59%) in the VRFB test, which was higher than that of the Nafion 212 membrane (EE=80.37%). In addition, the PyAPEF-100 membrane showed stable battery performance in 1 000-cycle tests, showing good membrane stability. The PyAPEF membrane prepared in this study achieved excellent battery efficiency in VRFB and has good application prospects in vanadium redox flow battery.
