Abstract:
A secondary battery has a safety vent formed on a can accommodating an electrode assembly. The safety vent is formed in a groove shape and the depth of the groove varies. The fracture site of the safety vent is controlled by adjusting the depth of the safety vent. The safety vent is prevented from damaging the electrode assembly when the electrode assembly is inserted in the can, and contacts the safety vent.
