Abstract: The present application provides a secondary battery including a first terminal component, a second terminal component, a cap plate, an electrode component and a resistance element. One of the first and second terminal components is electrically connected to the cap plate through the resistance element, while the other is insulated from the cap plate. The first terminal component includes a connecting plate and a turnable plate, and the connecting plate is attached to the turnable plate. When the secondary battery is in a normal state, a first electrode plate is electrically connected to the connecting plate through the turnable plate, and the second electrode plate is electrically connected to the second terminal component. When a pressure inside the secondary battery exceeds a reference pressure, the turnable plate can turn over to cut off an electrical connection between the turnable plate and the first electrode plate.

Abstract: The present disclosure relates to a vent for a secondary battery top cover, a top cover assembly, a secondary battery and a vehicle. The vent includes a flat base and a protrusion protruding outward with respect to flat base. The protrusion has a main nick and at least one branch nick connected to at least one end of the main nick. An angle formed between the main nick and the branch nick is more than zero. When the pressure inside the case increases excessively, gas causes stress concentration at the protrusion such that the vent is torn along the main nick and the at least one branch nick, thereby releasing the gas in the case, reducing explosion risk of the secondary battery, and improving safety of the secondary battery.
