Abstract

본 발명은 내부집전체와 상기 내부집전체의 외면을 둘러싸며 형성된 내부전극 활물질층을 구비하는 내부전극; 상기 내부전극의 외면을 둘러싸며 형성된, 전극의 단락을 방지하는 분리층; 및 상기 분리층의 외면을 둘러싸며 형성되고, 외부전극 활물질층, 열린 구조의 외부집전체 및 전도성 페이스트층을 구비하는 외부전극;을 포함하는 소정 형상의 수평 단면을 가지고 길이 방향으로 연장된 케이블형 이차전지에 대한 것이다. 본 발명의 전도성 페이스트층과 열린 구조의 외부집전체를 포함하는 외부전극은 가요성이 우수하므로 이를 구비하는 케이블형 이차전지의 가요성을 향상시킬 수 있다. 그리고, 상기 전도성 페이스트층은 경량의 소재로 구성되므로 케이블형 이차전지의 경량화에 기여할 수 있다.
