Disclosed is a battery pack comprising: a plurality of battery cells, each including an upper surface through which a pair of electrode terminals are protruded, a lower surface facing the upper surface, and a pair of long side surfaces and a pair of short side surfaces among surfaces connecting the upper surface and the lower surface, the long side surfaces having a relatively large area, and the short side surfaces having a relatively small area; and a cell frame that receives the battery cells, exposes the upper surfaces of the battery cells, and includes side plates for supporting the short side surfaces of the plurality of battery cells and end plates disposed at opposite ends to support the long side surfaces of the battery cells, wherein the end plates include protrusions protruding in a direction opposite to a direction in which the end plates faces long side surfaces of the battery cells at the opposite ends; and a recess located between the protrusions, depressed in a direction of long side surfaces of the battery cells, and providing an extra space for swelling. L'invention concerne un bloc-batterie comprenant : une pluralité de cellules de batterie, comprenant chacune une surface supérieure à travers laquelle une paire de bornes d'électrode font saillie, une surface inférieure faisant face à la surface supérieure, et une paire de surfaces latérales longues et une paire de surfaces latérales courtes parmi des surfaces reliant la surface supérieure et la surface inférieure, les surfaces latérales longues ayant une zone relativement grande, et les surfaces latérales courtes ayant une zone relativement petite; et un châssis de cellule qui reçoit les cellules de batterie, expose les surfaces supérieures des cellules de batterie, et comprend des plaques latérales pour supporter les surfaces latérales courtes de la pluralité de cellules de batterie et des plaques d'extrémité disposées à des extrémités opposées pour supporter les surfaces latérales longues des cellules de batterie, les plaques d'extrémité comprenant des saillies faisant saillie dans une direction opposée à une direction dans laquelle les plaques d'extrémité font face à des surfaces latérales longues des cellules de batterie au niveau des extrémités opposées; et un évidement situé entre les saillies, enfoncé dans une direction de surfaces latérales longues des cellules de batterie, et fournissant un espace supplémentaire pour gonflement. 한 쌍의 전극 단자가 인출되는 상면, 상면과 마주보는 하면, 상면과 하면을 연결하는 면들 중 상대적으로 면적이 큰 한 쌍의 장측면 및 상대적으로 작은 단측면을 포함하는 다수의 배터리 셀들 및 배터리 셀을 수용하며, 배터리 셀의 상면을 노출시키고, 다수의 배터리 셀들의 단측면을 지지하기 위한 사이드 플레이트와 배터리 셀의 장측면을 지지하기 위한 양 끝단의 엔드 플레이트를 포함하는 셀 프레임을 포함하며, 엔드 플레이트는 양 끝단에서 배터리 셀의 장측면과 마주하는 방향의 반대 방향으로 돌출된 돌출부들과 돌출부들 사이에 배터리 셀의 장측면 방향으로 들어간 스웰링 여유 공간을 위한 함몰부를 포함하는 배터리 팩이 개시된다.
