Abstract
In this study, we synthesized vinylbenzyl chloride-co-styrene-co hydroxyethyl acrylate (VBC-co-St-co-HEA) copolymer that can be applied to redox the flow battery process. The anion exchange membrane was prepared by the amination and crosslinking of VBC-co-St-co-HEA copolymer. The chemical structure and thermal properties of VBC-co-St-co-HEA copolymer and aminated VBC-co-St-co-HEA(AVSH) membrane were characterized by FTIR, 1H NMR, TGA, and GPC analysis. The membrane properties such as ion exchange capacity(IEC), electrical resistance, ion conductivity and efficiency of all-vanadium redox flow battery were measured. The IEC value, electrical resistance, and ion conductivity were 1.17 meq/g, 1.9 Ωㆍcm2, 0.009 S/cm, respectively. The charge-discharge efficiency, voltage efficiency and energy efficiency from all-vanadium redox flow battery test were 99.5, 72.6 and 72.1%, respectively.

본 연구에서는 전바나듐 레독스-흐름 전지용 음이온교환막의 제조를 위하여 vinylbenzyl chloride-co-styreneco-hydroxyethyl acrylate(VBC-co-St-co-HEA) 공중합체를 합성하였으며, 아민화 및 가교 반응을 통하여 음이온교환막을 제조하였다. 구조확인을 위하여 FTIR, 1H NMR, TGA, GPC 분석을 하였으며, 음이온교환막의 함수율, 이온교환용량, 전기저항, 이온전도도 및 전바나듐 레독스-흐름 전지의 효율을 측정하였다. 음이온교환막의 이온교환용량, 전기저항, 이온전도도는 각각 1.17 meq/g, 1.9 Ωㆍcm2, 0.009 S/cm이었으며, 전바나듐 레독스-흐름 전지 효율 실험 결과 충ㆍ방전효율, 전압효율 및 에너지효율은 각각 99.5, 72.6, 72.1%이었다.

Keywords: anion exchange membrane; water uptake; ion exchange capacity; electrical resistance; allvanadium redox flow battery.
