Abstract: A battery pack and an electric apparatus are disclosed. The battery pack includes a cell dummy and multiple battery cells, a housing, a mounting beam, and a support beam. The housing is provided with an accommodating cavity, and the cell dummy and the multiple battery cells are all disposed in the accommodating cavity. The mounting beam is disposed in a length direction of the accommodating cavity and defines, together with the accommodating cavity, a mounting space for accommodating the cell dummy and the multiple battery cells. The support beam is disposed in a width direction of the accommodating cavity and is mounted in a manner of fitting with the cell dummy. The cell dummy being provided with the support beam perpendicular to the mounting beam can enhance structural strength of the battery pack in the width direction of the accommodating cavity.

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.

Abstract: A battery includes a battery cell having a first wall provided with a pressure relief mechanism configured to be actuated when internal pressure or temperature of the battery cell reaches a threshold, a fire-fighting pipeline configured to accommodate a fire-fighting medium and discharge the fire-fighting medium when the pressure relief mechanism is actuated, a first fixing member disposed on a side of the fire-fighting pipeline close to the first wall and provided with first and second limiting parts, and a second fixing member disposed on a side of the fire-fighting pipeline away from the first wall and provided with third and fourth limiting parts. The third and first limiting parts match each other to fix the fire-fighting pipeline between the first and second fixing members. The fourth and second limiting parts match each other to limit the second fixing member in an extending direction of the fire-fighting pipeline.
