A battery, comprising: a battery cell, a first wall of the battery cell being provided with a pressure relief mechanism, and the pressure relief mechanism being configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; a fire-fighting pipeline configured to accommodate a fire-fighting medium and the fire-fighting pipeline being configured to 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, the first fixing member being provided with a first limiting part and a second limiting part; and a second fixing member, disposed on a side of the fire-fighting pipeline away from the first wall, the second fixing member being provided with a third limiting part and a fourth limiting part, the third limiting part and the first limiting part being matched with each other to fix the fire-fighting pipeline between the first fixing member and the second fixing member, the fourth limiting part and the second limiting part being matched with each other to limit the second fixing member in a first direction, and the first direction being parallel to an extending direction of the fire-fighting pipeline; the battery being characterized in that the third limiting part comprises a buckle extending in the first direction; the fourth limiting part is an opening disposed in the buckle; the first limiting part is a groove matched with the buckle; the second limiting part is a stopper matched with the opening, and when the buckle is buckled into the groove, the stopper is located within the opening to limit movement of the buckle in the first direction. a battery cell, a first wall of the battery cell being provided with a pressure relief mechanism, and the pressure relief mechanism being configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; a fire-fighting pipeline configured to accommodate a fire-fighting medium and the fire-fighting pipeline being configured to 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, the first fixing member being provided with a first limiting part and a second limiting part; and a second fixing member, disposed on a side of the fire-fighting pipeline away from the first wall, the second fixing member being provided with a third limiting part and a fourth limiting part, the third limiting part and the first limiting part being matched with each other to fix the fire-fighting pipeline between the first fixing member and the second fixing member, the fourth limiting part and the second limiting part being matched with each other to limit the second fixing member in a first direction, and the first direction being parallel to an extending direction of the fire-fighting pipeline; the battery being characterized in that the third limiting part comprises a buckle extending in the first direction; the fourth limiting part is an opening disposed in the buckle; the first limiting part is a groove matched with the buckle; the second limiting part is a stopper matched with the opening, and when the buckle is buckled into the groove, the stopper is located within the opening to limit movement of the buckle in the first direction.
