Abstract

전 바나듐계 레독스-흐름전지용 격막으로 폴리에틸렌 대칭막과 비대칭막을 사용하여 기상 중에서 클로로술폰화반응으로 제막하였다. 제막된 대칭막의 2 M KCl 수용액에서의 막저항은 반응시간 120분의 막에서 0.5 Ω·㎠이었고 비대칭막의 경우 1.0 Ω·㎠까지 감소하였다. 그리고 제조한 막을 레독스-흐름 전지의 격막으로 사용하여 충방전시 전기저항을 측정한 결과 대칭막이 비대칭막보다 낮은 전기저항을 나타내었고, 산성의 바나듐수용액에 침적하여 측정한 내구성은 대칭막과 비대칭막의 경우 각각 약 3개월 정도의 비슷한 수명을 나타내었다.
Chlorosulfonated homogeneous and asymmetric membranes were tested as separator for the all vanadium redox-flow battery. The membranes were prepared by chlorosulfonation of the polyethylene film in vapor phase. In the case of a homogeneous membrane, area resistivity of 0.5 Ω·cm2 in 2M KCl aqueous solution was obtained at chlorosulfonation time of 120 min. In the case of an asymmetric membrane, area resistivity 1.0 Ω·cm2 in 2M KCl aquous solution was reached at chlorosulfonation time of 120 min. The electrical resistance of membranes in the redox-flow battery were also measured. The electrical resistance of homogeneous membrane has a lower value than that of an asymmetric membrane. The durability of chlorosulfonated homogeneous and asymmetric membrane which is determined by the oxidation degradation in acidic vanadium solution, was 3 months, respectively.
