제목 Anion exchange membrane prepared from imidazolium grafted poly (arylene ether ketone) with enhanced durability for vanadium redox flow battery
초록 The anion exchange membrane was synthesized from poly(arylene ether ketone) with 1-(3-aminopropyl) imidazole pendant groups (PAEK-API) for vanadium redox flow battery. The properties of the PAEK-API membranes were compared with those of Nafion® 117 membrane. All of the synthesized membranes showed higher ion exchange capacity than Nafion®117 membrane. Also the membranes showed lower vanadium ion permeability than Nafion® 117 membrane, and excellent chemical stability in electrolyte solution because of Donnan exclusion phenomena. During the 100 cycling tests, the PAEK-API 2.0 membrane showed higher coulombic and energy efficiencies than Nafion® 117 membrane without any degradation.
