Abstract

본 발명은 전극조립체가 각형 캔에 내장되어 있는 이차전지로서, 상기 각형 캔의 개방 상단에 장착되는 베이스 플레이트의 전해액 주입구는 내면이 하부 방향으로 직경이 작아지는 챔퍼(chamfer) 구조의 상부와, 상기 챔퍼 구조에 연속하여 형성되어 있는 비챔퍼 구조의 하부로 형성되어 있고, 상기 전해액 주입구에 밀봉부재를 압입할 때, 전해액 주입구 형상으로 변형된 밀봉부재는 챔퍼 구조와 밀봉부재 상호간의 전단 응력에 의해 상호 밀착되고 비챔퍼 구조와의 마찰력에 의해 밀봉 상태를 형성하는 것을 특징으로 하는 이차전지를 제공한다. 본 발명에 따른 이차전지는 불량률의 발생을 감소시키고 용접공정을 수행하지 않고도 밀봉성을 향상시킬 수 있다.
