Abstract: This application relates to a cover assembly of a secondary battery. The cover assembly includes a cover plate with an air hole; a blocker inserted into and blocking the air hole; a sealing member disposed between the blocker and the cover plate configured to seal a gap between the blocker and the cover plate; and a fastener disposed inside the air hole. The fastener is connected to the cover plate, the blocker is connected to the cover plate through the fastener. The fastener is configured to deform in response to a temperature rise, so that the blocker stops blocking the air hole. The blocker stops blocking the air hole as a temperature inside a housing rises, to discharge gas from the housing through the air hole. In this way, the secondary battery can be prevented from an explosion, while partial heat is taken away through gas discharge.
