Summary:The present invention relates to an electrode assembly and a lithium secondary battery comprising same. The electrode assembly has a form in which an electrode, a separator, and a counter electrode are laminated, wherein: each of the electrode and the counter electrode includes a tab extending from a current collector; all four surfaces of the electrode, including the surface from which the tab extends, have sizes larger than those of the counter electrode, so that the electrode has exposed portions; and an insulation layer is formed on the tab part of the electrode and an edge part of the electrode. La présente invention concerne un ensemble d'électrodes et une batterie secondaire le comprenant. L'ensemble d'électrodes a une forme dans laquelle une électrode, un séparateur et une contre-électrode sont stratifiés, dans lequel : chacune de l'électrode et de la contre-électrode comprend une languette s'étendant à partir d'un collecteur de courant ; toutes les quatre surfaces de l'électrode, comprenant la surface à partir de laquelle s'étend la languette, ont des dimensions supérieures à celles de la contre-électrode, de telle sorte que l'électrode a des parties exposées ; et une couche d'isolation est formée sur la partie de languette de l'électrode et une partie de bord de l'électrode. 본 발명은 전극, 분리막 및 대향 전극을 적층한 형태의 전극조립체로서,상기 전극 및 대향 전극은, 집전체로부터 연장된 탭을 각각 포함하고,상기 전극은 대향 전극보다 탭이 연장된 면을 포함하여 4개의 모든 면에서, 그 크기가 커 노출된 부위를 가지며, 상기 전극의 탭부 및 상기 전극의 테두리부 상에 절연층이 형성되어 있는 전극 조립체 및 이를 포함하는 리튬 이차전지에 관한 것이다.
