Summary:The present invention relates to a battery module comprising a venting structure, and a battery pack comprising same. The battery module according to an embodiment of the present invention comprises: a battery cell stack which is a stack of a plurality of battery cells; a module frame for accommodating the battery cell stack; and end plates covering the front and rear surfaces of the battery cell stack. A venting part is formed on the top surface of the module frame. The battery cell comprises: a cell body; electrode leads protruding from both ends of the cell body; and a terrace part extending from the cell body in the protruding direction of the electrode lead. The venting part is formed closer to the position of the terrace part than the cell body. La présente invention concerne un module de batterie comportant une structure d'aération, et un bloc-batterie le comprenant. Le module de batterie selon un mode de réalisation de la présente invention comprend : un empilement de cellules de batterie qui est un empilement d'une pluralité de cellules de batterie ; un cadre de module pour recevoir l'empilement de cellules de batterie ; et des plaques d'extrémité recouvrant les surfaces avant et arrière de l'empilement de cellules de batterie. Une partie d'aération est formée sur la surface supérieure du cadre de module. La cellule de batterie comprend : un corps de cellule ; des fils d'électrode faisant saillie à partir des deux extrémités du corps de cellule ; et une partie terrasse s'étendant à partir du corps de cellule dans la direction faisant saillie du fil d'électrode. La partie d'aération est formée plus près de la position de la partie terrasse que le corps de cellule. 본 발명은 벤팅 구조를 포함하는 전지 모듈 및 이를 포함하는 전지팩에 관한 것으로, 본 발명의 일 실시예에 따른 전지 모듈은, 복수의 전지셀이 적층되어 있는 전지셀 적층체; 상기 전지셀 적층체를 수용하는 모듈 프레임; 및 상기 전지셀 적층체의 전후면을 커버하는 엔드 플레이트를 포함하고, 상기 모듈 프레임의 상면에는 벤팅부가 형성되고, 상기 전지셀은, 셀 본체; 상기 셀 본체의 양단으로부터 돌출 형성된 전극 리드; 및 상기 전극 리드가 돌출된 방향으로 상기 셀 본체로부터 연장 형성된 테라스부를 포함하고, 상기 벤팅부는 상기 셀 본체보다 상기 테라스부가 위치한 부분에 인접하여 형성된다.
