BOX BODY, BATTERY, ELECTRIC APPARATUS AND MANUFACTUIRNG METHOD OF THE BATTERY

A box body, a battery, an electric apparatus and a manufacturing method of the battery, belonging to the field of energy storage devices. The box body includes a cooling device and a plurality of walls, where the plurality of walls enclose an accommodating space for accommodating a battery cell, an interior of at least one wall is provided with a first flow channel, and the first flow channel is used for discharging emissions generated by thermal runaway of the battery cell out of the box body. The cooling device is arranged in the first flow channel and used for cooling the emissions flowing through the cooling device. The cooling effect of the cooling device becomes better, the possibility of firing and burning of the emissions is reduced, and the safety of the battery is improved.
