This application relates to the field of battery technologies, and in particular, to a battery, an electric apparatus, and a method and device for preparing battery. This application is intended to resolve the problem of proneness to accidents due to difficult release of emissions during thermal runaway of a battery. The battery includes a battery cell, where the battery cell includes a pressure relief mechanism, and the pressure relief mechanism is configured to actuate release of internal pressure of the battery cell when the internal pressure or internal temperature of the battery cell reaches a threshold; and further includes a fire prevention chamber, a collection chamber, and an isolation member, where the isolation member is configured to isolate the fire prevention chamber from the collection chamber and allow passage of the emissions during actuation of the pressure relief mechanism, so that the emissions enter the collection chamber through the fire prevention chamber. An electric apparatus using such battery is also disclosed. The battery in embodiments of this application has beneficial effects of collecting the emissions generated in thermal runaway of the battery cell while implementing fire extinguishing, thereby reducing safety accidents.
