Abstract
A battery, including an adhesive, where the adhesive is provided between a packaging bag and the battery cell, and the adhesive is adhered to an outer surface of the battery cell. The adhesive includes an adhesive layer, where the adhesive layer includes an adhesive material and a heat-absorbing material. When the temperature of the battery cell is 130° C., an adhesion force between the adhesive and the outer surface of the battery cell is m, and m satisfies m≥3 N. At room temperature (25° C.), the adhesive can be fixed to the outer surface of the battery cell. When the temperature of the battery cell rises, the adhesive can still be adhered to the outer surface of the battery cell, reducing the temperature of the battery cell and increasing the critical temperature for thermal runaway of the battery cell.
