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.

Abstract: A battery includes multiple battery cells arranged in a first direction and each provided with a pressure relief mechanism configured to be actuated when the internal pressure or temperature of the battery cell reaches a threshold to relieve the internal pressure, a fire-extinguishing pipe configured to accommodate a fire-extinguishing medium and to release the fire-extinguishing medium during actuation of the pressure relief mechanism, a restraining member disposed at an end of the multiple battery cells along the first direction and configured to restrain the multiple battery cells in the first direction, and a fastener attached to a surface of the restraining member facing toward the fire-extinguishing pipe and configured to fasten the fire-extinguishing pipe.
