Abstract: Embodiments of this application provide a box, a battery, and an apparatus, and relate to the field of battery technologies. The box is provided with a discharge hole, and the discharge hole is configured to discharge, from inside the box, flame produced when thermal runaway occurs in a battery cell. The box is further provided with a fire extinguishing member that is configured to extinguish the flame for cooling when the flame passes through the discharge hole. In this application, the discharge hole and the fire extinguishing member are arranged in the box, so that when the flame produced when thermal runaway occurs in the battery cell passes through the discharge hole, the fire extinguishing member can release a fire extinguishing agent to extinguish the flame for cooling. This prevents the flame from being discharged from inside the box through the discharge hole, thereby improving safety performance of the battery.
