Abstract
A pouch case is provided which includes: a forming portion having a predetermined depth, and allowing each of a first end surface and a second end surface of the electrode assembly to be received therein; a notch portion extending from each of opposite ends of the forming portion so as to have a depth gradually decreasing from a depth defined by the thickness of the electrode assembly received in the forming portion; and a storing portion covering a remaining portion other than a portion of the electrode assembly received in the forming portion. By effectively controlling a protruding structure of the pouch case sealed on the first and second end surfaces of the electrode assembly received therein, it is possible to improve contact reliability between the stacked battery cells.
