摘要： The present application provides a lithium-ion battery, which comprises: a wound-type cell formed by winding a positive electrode plate, a separator and a negative electrode plate, a width of the separator is greater than widths of the positive electrode plate and the negative electrode plate; an electrolyte; and a packaging film packaging the wound-type cell and accommodating the electrolyte; a wound ending of the wound-type cell is adhered with a single-sided adhesive layer, an adhesive of the single-sided adhesive layer is a flowable curing adhesive, the wound-type cell and the packaging film are adhered together by the curing adhesive which flows and flows out from a periphery of the single-sided adhesive layer. The single-sided adhesive layer can prevent the wound-type cell from loosening or deforming, rupturing of the positive electrode tab and the negative electrode tab and bursting open of a top-seal in the process of dropping or tumbling.
