Abstract

본 발명은 전극조립체에 관한 것으로, 보다 상세하게는 스태킹(stacking) 구조의 유닛셀 다수개를 긴 시트형 분리필름 상에 위치시킨 상태에서 권취한 구조로, 상기 유닛셀들은 전극 합제의 구성에 따라 2 또는 그 이상의 종류로 이루어진 전극조립체로서, 상기 스태킹 구조의 유닛셀에 적층되는 분리막은 코팅물질이 양면 코팅된 것이며, 상기 긴 시트형 분리필름은 코팅물질을 단면 코팅하여, 전지 제조 시 초기 저항을 줄이면서, 전지 제조의 공정성을 향상함과 동시에 전지 수명이 기존의 전지와 동등한 전극조립체 및 이를 포함하는 리튬 이차전지에 관한 것이다.
