摘要：A secondary battery has a safety vent, and the safety vent has an asymmetricstructure and provides a substantial opening for the battery, instead of having a localcrack, to rapidly vent to atmosphere in order to prevent the secondary battery frombursting when the internal pressure of a battery increases excessively or external impact
is applied thereto. The secondary battery includes an electrode assembly
charging/discharging functions, a can housing the electrode assembly, a cap assemblythat includes a cap plate closing up an open part of the can, and a safety vent having anasymmetric track shape that is provided in the cap plate of the cap assembly.
