英文摘要	sulfonated poly(ether ether ketone) (c-speek) membranes with pendent carboxylic acid groups are prepared and first investigated for vanadium flow battery (vfb) application. the introduction of carboxylic acid groups can effectively improve the ion conductivities of c-speek membranes, while, keep their ion selectivities. the prepared c-speek membranes exhibit excellent performance under vfb operating condition. vfb single cell assembled with c-speek-50 membranes shows much higher energy efficiency (85% vs 82%) and columbic efficiency (97.3% vs 94.6%) than that assembled with nation 115. the membrane keeps a stable performance after more than 180 cycles charge discharge test, showing good stability.
