This application discloses a bidirectional vent valve, a battery, and an electrical device. The bidirectional vent valve includes: a valve seat, where the valve seat is configured to form a gas duct, and the gas duct includes a first end and a second end; a bidirectional valve assembly, where the bidirectional valve assembly is movably disposed in the gas duct, and is configured to open or close the gas duct through movement relative to the gas duct; and a first elastic component, configured to exert a force on the bidirectional valve assembly to close the air duct, and, when an air pressure difference between the first end and the second end of the gas duct is greater than a first threshold, the bidirectional valve assembly is configured to overcome the force of the first elastic component to open the gas duct.
