Abstract
A thermal expansion coefficient of a battery case may be lower than those of an insulating film and a separator. Portions of the insulating film, which are held in contact with the electrode body and the battery case, may be adhered to the separator, which is positioned on the outermost surface of the electrode body, and the battery case, respectively. A first 90 degree peeling strength of an adhesion portion between the insulating film and the battery case is higher than a second 90 degree peeling strength of an adhesion portion between the insulating film and the separator. The first 90 degree peeling strength may be 15 mN/cm or higher, and the second 90 degree peeling strength may be 5 mN/cm or higher.
