Abstract

disclosure belongs to the technical field of batteries. Provided in the embodiments of the present disclosure are a battery, a battery pack and an electric apparatus. The battery comprises a temperature adjustment container and battery cells. The temperature adjustment container has a temperature adjustment chamber, and an inlet and an outlet that are respectively communicated with the temperature adjustment chamber, a weakened area being formed on the chamber wall of the temperature adjustment chamber. The battery cells are arranged on one side or two opposite sides of the temperature adjustment container in a preset direction, the preset direction intersecting the surfaces having the largest areas of the battery cells. When thermal runaway of the battery cells occurs, the pressure bearing capacity of the weakened area is smaller than the pressure bearing capacity of other areas except the weakened area of the chamber wall of the temperature adjustment chamber, such that fluid in the temperature adjustment chamber can flow out from a position corresponding to the weakened area. When thermal runaway occurs, the pressure of the temperature adjustment chamber is increased to open the weakened area, so as to cool battery cells undergoing thermal runaway rapidly, thus inhibiting thermal runaway of battery packs.
