  • Pouch type secondary battery with safety vent
    Patent number: 7122276
    Abstract: A pouch type secondary battery has a safety vent which prevents explosion and fire by removing a sealing mechanism of a pouch casing when the internal temperature increases due to overcharging, overdischarging or over-heating, and which exhausts internal gas before explosion and fire of the battery when the internal gas pressure excessively increases due to overcharging, overdischarging or internal short-circuit.
