Abstract: A battery box, a battery, an electric device, and a method and device for manufacturing battery are provided. The battery box includes a support member and an expansion member. The expansion member presses the support member so that the volumetric capacity of an accommodating space for accommodating binder between the support member and the battery cell changes. The volumetric capacity of the accommodating space can be adjusted. Therefore, under the condition that the accommodating space has a relatively large volumetric capacity, it is simple to inject an appropriate amount of binder; and after the binder is injected, the volumetric capacity of the accommodating space is reduced so that the binder spreads throughout the accommodating space. The foregoing box allows for binder injection reduction during battery assembly, thereby reducing the possibility of binder overflow, improving the safety performance of the battery, and also increasing the energy density of the battery.
