Abstract

본 발명은 리튬 이차전지용 비수 전해액 및 이를 구비한 리튬 이차전지에 관한 것이다. 본 발명의 리튬 이차전지용 비수 전해액은 특정의 화학식으로 표시되며, 수산기와 탄소 이중결합을 갖는 탄화수소기를 동시에 갖는 실리콘계 화합물을 더 포함한다. 본 발명의 비수계 전해액을 리튬 이차전지에 사용시 충방전 싸이클 수명특성이 개선될 뿐만 아니라, 전지가 만충전 상태(fully-charged state)에서 고온에 보관되거나 충방전이 진행되더라도 전해액의 분해반응이 억제됨으로, 스웰링(swelling) 현상을 개선하여 전지의 고온 수명특성이 향상된다.
