To improve the performance of a low cost sulfonated poly(phthalazinone ether ketone) (SPPEK) membrane in vanadium redox flow battery (VRFB), composite membranes composed of SPPEK and tungstophosphoric acid (TPA) with 8–25wt% concentration were prepared by solution casting. The results of scanning el...
