  • Patent number: 10340500
    Abstract: A pouch battery having improved overcharging safety includes a CID interrupting an electrical connection between an electrode assembly and a lead tab when the pouch is expanded. When the pouch is expanded, the CID discharges gas generated inside the pouch to the outside, and at the time of overcharging a secondary battery, the CID interrupts a flow of current introduced into the secondary battery and discharges the gas generated due to the overcharging to the outside of the pouch, thereby reducing an ignition risk and improving the overcharging safety.
