| description | The present invention relates to a pouch exterior material for accommodating and packaging an electrode assembly therein, and specifically, to a pouch exterior material for a secondary battery and a secondary battery including the same, wherein the pouch exterior material is a laminate sheet including one or more metal thin film layers and one or more resin layers, the pouch exterior material is constituted by including an elastic layer of an elastic material that is interposed between the metal thin film layers and the resin layers and laminated, and the electrode assembly is packaged inside the pouch exterior material to form the secondary battery, so that premature deterioration due to non-uniform surface pressure of the secondary battery is prevented, thereby improving the performance and lifespan of the secondary battery.
본 발명은 내부에 전극 조립체를 수납하여 패키징하는 파우치 외장재에 있어서, 상기 파우치 외장재는 하나 이상의 금속 박막층 및 하나 이상의 수지층을 포함한 라미네이트 시트이며, 상기 금속 박막층과 수지층 사이에 개재되어 적층된 탄성 재질의 탄성층을 포함하여 파우치 외장재가 구성되고, 상기 파우치 외장재의 내부에 전극 조립체가 수납된 상태로 패키징되어 이차전지가 구성됨에 따라, 이차전지의 면압 불균일에 의한 조기 열화 현상이 방지되어, 이차전지의 성능 및 수명을 향상시킬 수 있는 이차전지용 파우치 외장재 및 이를 포함한 이차전지에 관한 것이다. |
