Abstract
The present invention relates to a secondary battery, which detects a displacement of a gas discharging part and prevents battery cell swelling, and a system for charging a secondary battery and a method of manufacturing a secondary battery. The secondary battery include a gas discharging part, which is positioned at one end of a sealing part that seals an electrode assembly and induces a discharge of gas by weakening bonding force more than other attachment portions of the sealing part, and a detecting part which detects a displacement generated in the gas discharging part and generates an electric signal.
