Abstract: A battery safety vent is provided. The battery safety vent comprises: an explosion-proof film fixed on a battery cover plate; a safety vent cover covering above the explosion-proof film and having a pressure release aperture; and an explosion-proof pin disposed at a top of the safety vent cover, in which a free head of the pin is blunt and points to the explosion-proof film. A battery having the battery safety vent is further provided. The battery safety vent may release the internal pressure of the battery via a large scale broken explosion-proof film if the internal pressure is high, so as to ensure the safety of the battery.
