  • POUCH HAVING IMPROVED SAFETY, POUCH-TYPE SECONDARY BATTERY INCLUDING THE SAME, AND MEDIUM-TO-LARGE BATTERY PACK
    Publication number: 20120040235
    Abstract: Provided are a pouch-type secondary battery having improved safety, and a battery pack including the pouch-type secondary battery. When inner pressure of a pouch is increased by an overdischarge, the pouch is deformed to separate electrode leads from electrode tabs. When the secondary battery is manufactured, an additional material or device is unnecessary. In addition, since the pouch-type secondary battery fundamentally cuts off electric current when gas is generated therein, the service life and safety of the secondary battery can be significantly improved, and the manufacturing costs and the weight thereof can be reduced. Furthermore, the shape of the secondary battery can be easily modified.
