The present invention relates to a pouch-shaped battery cell including an electrode assembly with a venting adjustment member. The pouch-shaped battery case can be configured to receive the electrode assembly, with an electrode lead extending from the electrode assembly. A part of the electrode lead can protrude outwards from the pouch-shaped battery case. A sealed portion can be formed at an outer periphery of the pouch-shaped battery case. The venting adjustment member can be mounted to a part of the sealed portion in a direction in which the electrode lead protrudes. The venting adjustment member is configured to adjust opening and closing of the sealed portion having the venting adjustment member mounted thereto based on the pressure of gas in the pouch-shaped battery case.
