바나듐 레독스 흐름전지용 Poly(arylene ether sulfone) 막의 특성
Characteristics of Poly(arylene ether sulfone) Membrane for Vanadium Redox Flow Battery
최근에 대용량 에너지 저장 시스템으로 레독스 흐름전지(Redox Flow Battery, RFB)가 활발히 연구·개발되고 있다. 불소계막을 대신할 저가의 탄화수소막이 RFB막으로 주목받고 있다. 본 연구에서는 Poly(arylene ether sulfone) (PAES) 막을 사용해 고가의 불소계막과 그 특성을 바나듐 레독스 흐름전지(VRB, Vanadium Redox Flow Battery)조건에서 비교하였다. 바나듐 이온투과도, 이온 교환 용량, OCV 변화, 팽윤, 충·방전 곡선, 에너지 효율 등을 측정했다. PAES 막은 Nafion 117막에 비해 바나듐 이온투과도가 낮고, 이온교환용량은 커서 Nafion 117을 사용한 RFB보다 에너지 효율이 높았다.
Recently, there are many efforts focused on development of Redox Flow Battery (RFB) for large energy storage system. Economical hydrocarbon membranes alternative to fluorinated membranes for RFB membrane are receiving attention. In this study, characteristics of poly(arylene ether sulfone) (PAES) were compared with expensive fluorinated membrane at VRB (Vanadium Redox Flow Battery) operation condition. Permeability of vanadium ion through membrane, ion exchange capacity (IEC), change of OCV, swelling, charge-discharge curves and energy efficiency were measured. PAES membrane showed lower permeability of vanadium ion, higher IEC and then higher energy efficiency compared with Nafion 117 membranes.
