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.
