Abstract: This application discloses a battery cell, a battery, and an electric apparatus. The battery cell includes an electrode assembly. The electrode assembly includes a positive electrode plate, a negative electrode plate, a separator, an insulation layer, and an adhesive layer. The positive electrode plate, the separator, and the negative electrode plate are stacked and wound, and the electrode assembly has bent regions. At least a portion of the insulation layer and at least a portion of the adhesive layer are disposed in the bent region, and the insulation layer is adhered to the positive electrode plate or the negative electrode plate through the adhesive layer. In a thickness direction of the insulation layer, a projected area of the adhesive layer is smaller than a projected area of the insulation layer.

Abstract: This application discloses a battery cell, a battery, and an electric apparatus. The battery cell includes at least one electrode assembly. The electrode assembly includes a positive electrode plate, a negative electrode plate, a separator, and a porous insulation layer. The positive electrode plate, the separator, and the negative electrode plate are stacked and wound. At least a portion of the porous insulation layer is disposed in a bent region of the electrode assembly, and the porous insulation layer is disposed between the positive electrode plate and the separator or disposed between the negative electrode plate and the separator. Based on the above structure, the service life of the battery cell can correspondingly be prolonged, and the safety of the battery cell can correspondingly be improved.
