Abstract

본 발명은 수분 침투에 대한 장기 신뢰성이 향상된 이차 전지를 개시한다. 본 발명에 따른 파우치형 이차 전지는, 전극 리드가 부착된 전극 조립체; 및 상기 전극 리드의 일부가 외부로 노출되도록 상기 전극 조립체를 수납하며 가장자리를 따라 실링부가 형성된 파우치 포장재를 포함하고, 상기 실링부의 특성 길이(Characteristic length)가 10 내지 19mm2/mm인 것을 특징으로 한다. 본 발명에 따르면, 파우치형 이차 전지의 실링부에 대한 특성 길이를 일정 범위로 제한함으로써 실링부가 차지하는 면적으로 인한 이차 전지의 용량 감소를 최대한 억제하면서도 이차 전지의 장기 사용에 따른 수분 침투 신뢰성을 향상시킬 수 있다.
