Abstract

본 발명은 블렌드 고체 고분자 전해질에 관한 것이다. 본 발명의 블렌드 고체 고분자 전해질은 폴리올리고옥시에틸옥시세바코일 약 10~60중량%, 폴리에틸렌옥사이드 약 10~60중량%, 리튬염 약 15~25중량%, 바람직하게는 약 16~64중량%, 약 16~64 중량% 및 약 19~20중량%로 조성된다. 본 발명의 블렌드 고체 고분자 전해질들은 기계적 물성 및 이온 전도 특성이 모두 우수하고, 유기 용매를 전혀 포함하고 있지 않아 전해액 누출 및 전극의 부식 문제가 없으며, 상용성이 뛰어나고, 특히 제조공정이 간단하고 가격이 저렴하여 인-라인 프로세스를 이용한 고분자 전해질 필름 제조시 공정성이 크게 향상되어 리튬 고분자 이차전지를 비롯한 여러 전기화학장치에 유용하게 사용될 수 있다.
