Abstract
In a safety vent part and an electric energy storage device having the same, the safety vent part includes a plate coupled to the device, a metal sheet and a metal cap. A hole having a step portion is formed through the plate, and is in communication with an interior of the device. The metal cap having an exhaust nozzle corresponding the hole is coupled into the step portion by a tight fit. The metal sheet is disposed between a bottom surface of the step portion and the metal cap. When an internal pressure of the device is higher than a predetermined breaking pressure, the internal pressure of the device breaks the metal sheet. A gas generated abnormally in the device is exhausted through the hole and exhaust nozzle.
