Summary:The present invention relates to an electrode assembly and a battery cell including same. In the electrode assembly according to an embodiment of the present invention, a plurality of unit cells, each comprising a negative electrode, a positive electrode, and a separator, are stacked, and separators are disposed between the plurality of unit cells, the electrode assembly comprising: a first unit cell in which one end of the negative electrode protrudes further than one end of the positive electrode; and a second unit cell in which one end of the positive electrode protrudes further than one end of the negative electrode. La présente invention concerne un ensemble électrode et une cellule de batterie le comprenant. Dans l'ensemble électrode selon un mode de réalisation de la présente invention, une pluralité de cellules unitaires, comprenant chacune une électrode négative, une électrode positive et un séparateur, sont empilées, et des séparateurs sont disposés entre la pluralité de cellules unitaires, l'ensemble électrode comprenant : une première cellule unitaire dans laquelle une extrémité de l'électrode négative fait saillie plus loin qu'une extrémité de l'électrode positive ; et une seconde cellule unitaire dans laquelle une extrémité de l'électrode positive fait saillie plus loin qu'une extrémité de l'électrode négative. 본 발명은 전극 조립체 및 이를 포함하는 전지셀을 포함하고, 본 발명의 일 실시예에 따른 음극, 양극, 및 분리막을 포함하는 복수의 단위셀이 적층되고, 상기 복수의 단위셀 사이에 위치하는 분리막을 포함하는 전극 조립체는, 상기 음극의 일단부가 상기 양극의 일단부보다 돌출된 제1 단위셀; 및 상기 양극의 일단부가 상기 음극의 일단부보다 돌출된 제2 단위셀을 포함한다.
