Abstract
A pouch battery contains a pouch, an electrode material and a safety protection device. The electrode material is located in the pouch. The safety protection device is configured to generate an action based on a change in gas pressure within the pouch. In this way, even if the pouch battery is abnormal, its internal circuit can be cut off in time to avoid providing power to external devices while being under abnormal conditions.
