Abstract
A new type of polymer gel electrolyte was prepared from poly(ethylene glycol) diacrylate(PEGDA) and 1-butyl-3-methylimidazolium bis((trifluoromethyl) sulfonyl) amide(BuMeIm+Tf2N-) ionic liquid. The effect of the ionic liquid on ionic conductivity of the gel polymer electrolyte was investigated. It was observed that the gel polymer electrolyte having the ionic liquid exhibited higher ionic conductivity (ca. 10-3S/cm) as well as electrochemical stability than that using organic solvent.

본 연구에서는 폴리(에틸렌 글리콜) 디아크릴레이트(PEGDA) 고분자 매트릭스에 이온성 액체인 1-butyl-3-methyl-imidazolium bis((trifluoromethyl) sulfonyl) amide(BuMeIm+Tf2N-)로 구성된 전해질 용액을 함유하는 젤 형태의 고분자 전해질을 제조하였다. 이온성 액체가 고분자 전해질의 이온 전도도에 미치는 영향을 조사하였으며, 기존의 유기 용매를 넣은 고분자 전해질보다 높은 이온 전도도(ca. 10-3S/cm)와 전기 화학적 안정성을 나타냄을 알 수 있었다.
