Disclosed is a pack having a gas shifting pipe. A pouch-type secondary battery (10) included in a battery pack (100) according to the present invention is connected to a gas shifting pipe (60). A swelling phenomenon that a pouch case swells up due to the generation of a gas can be generated in the pouch-type secondary battery (10). Therefore, if a gas is generated in a pouch-type secondary battery (10), the gas moves to an adjacent pouch-type secondary battery (10) through the gas shifting pipe (60). The pouch-type secondary battery (10) having the gas is connected to another pouch-type secondary battery (10) through the gas shifting pipe (60). Therefore, the internal gas pressure of all the pouch-type secondary batteries (10) included in the battery pack (100) is same. |
