Summary: | A box body (31), a battery (30), an electric device, and a manufacturing method for the battery (30), relating to the technical field of energy storage devices. The box body (31) is used for the battery (30); the battery (30) comprises battery cells (32); the box body (31) comprises a plurality of box walls (310); the plurality of box walls (310) define a first chamber (311) used for accommodating the battery cells (32); a second chamber (3101) used for accommodating a firefighting agent is formed in at least one box wall (310); and the first chamber (311) and the second chamber (3101) are configured to be capable of being communicated with each other when the battery cells (32) are in thermal runaway, so that the firefighting agent releases a firefighting medium into the first chamber (311). The box body (31), the battery (30), the electric device, and the manufacturing method for the battery (30) can improve the safety performance of the battery (30). |
