The present invention relates to a swelling CID comprising: a battery unit connection terminal fixed to a pouch; and a lead tab connection terminal which is fixed to the pouch and electrically connects to the battery unit connection terminal. When the pouch swells, any one among the battery unit connection terminal and the lead tab connection terminal is destroyed by the swelling force of the pouch, thereby breaking the electrical connection. When the pouch swells because of overcharge and the like, the battery unit is physically disconnected from the external, thereby breaking the electrical connection between the battery unit and the external. Therefore, provided is a swelling CID having an effect that a level stability of a pouch cell is secured. |
