    Abstract: Disclosed herein is a battery cell including a battery case having an initial position and an assembled position, and an electrode assembly. The electrode assembly may include a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode. The electrode assembly may be mounted in the battery case in the assembled position. The battery case may include a first receiving unit and a second receiving unit formed in the battery case and spaced apart from each other when the battery case is in the initial position, the first and second receiving units receiving a respective portion of the electrode assembly when the battery case is in the assembled position, and a bridge region having a recessed portion that is recessed in a direction identical to the depth direction of each of the receiving units when the battery case is in the initial position.

    Abstract: Provided are a pouch for a secondary battery, which is capable of minimizing a folded area of a bridge part of the pouch that is manufactured by folding two accommodation parts to overlap each other, and a die for forming the pouch for the secondary battery. The pouch for the secondary battery includes a lower accommodation part accommodating an electrode assembly therein, an upper accommodation part covering an opening of the lower accommodation part, and a bridge part connecting the lower accommodation part to the upper accommodation part. When the lower accommodation part and the upper accommodation part are unfolded, a height of the bridge part, which is measured from a bottom surface of the lower accommodation part, is lower than that of the lower accommodation part, which is measured from the bottom surface of the lower accommodation part.
