Abstract

본 발명은 양극/분리막/음극 구조의 전극조립체(젤리-롤)가 원통형 캔에 내장되어 있는 구조의 전지에서 캔의 개방 상단부에 탑재되는 캡 어셈블리로서, 전지의 고압 가스에 의해 파열되도록 소정의 노치가 형성되어 있는 안전벤트; 상기 안전벤트의 외주면을 따라 그것에 접속되어 있는 돌출형의 상단 캡; 상기 상단 캡의 외주면에 장착되어 있는 가스켓; 및 전지의 발화를 방지하기 위한 소화성분을 포함하고 있고, 적어도 일부가 상단 캡과 가스켓의 계면에 장착되어 있는 소화부재; 를 포함하는 것을 특징으로 하는 캡 어셈블리를 제공한다.
