Abstract

본 발명은 수지층과 금속층을 포함하는 라미네이트 시트의 전지케이스에 전극조립체 및 전해액이 내장되어 있는 전지셀을 제조하는 방법으로서, (a) 전지케이스에 전극조립체를 장착한 상태에서 전지케이스의 외주면 중 일측 단부를 제외한 나머지 부위들을 열융착시켜 실링하는 과정; (b) 미실링 상태의 상기 단부를 통해 전해액을 주입한 후 상기 단부를 열융착에 의해 실링하는 과정; (c) 충전과 방전을 수행하여 전지셀을 활성화시키는 과정; (d) 상기 활성화 과정에서 발생한 가스와 잉여 전해액을 원심력에 의해 전지셀의 상기 단부로 이동시키는 과정; 및 (e) 상기 단부에서 가스와 잉여 전해액을 제거하는 과정;을 포함하는 전지셀 제조방법을 제공한다.
