BATTERY AND ELECTRIC DEVICE

The present application discloses a battery and an electric device. The battery comprises a case, a heat exchange assembly, and at least one battery cell; the case comprises a plurality of first side beams, and the plurality of first side beams are connected to define a first accommodating cavity; the at least one battery cell is located in the first accommodating cavity; the heat exchange assembly is located in the first accommodating cavity, and comprises at least one heat exchange piece used for exchanging heat with the battery cell; and an accommodating slot is formed in at least one first side beam, and the at least one heat exchange piece is at least partially accommodated in the accommodating slot. In this way, the internal space of the case is saved, the space utilization rate of the battery is improved, and the structural compactness of the battery is improved, thereby improving the volumetric energy density of the battery.
