Claims

[Claims for Utility Model Registration] (1) An exterior label is wound and pasted around the outer periphery of the unit cell with a predetermined overlap margin, and this exterior label is heat-shrinked to cover the shoulders of the top and bottom surfaces of the unit cell. In the label-wrapped cylindrical battery which is folded and adhered to the outer label: The label-wrapped cylinder is characterized in that a concave cutout is formed at a corner of the winding start end and/or the winding end of the outer label. shaped battery. (2) The concave shape of the notch is in the shape of an inverted circular arc or an L shape, and its dimensions are less than or equal to the overlapping margin between the winding start and end ends of the outer label and the width of the bending margin for the unit cell. 2. The label-wrapped cylindrical battery according to claim 1, wherein the battery has the following relationship: . Notch length in the winding direction ≦ (Maximum length in the label winding direction - Maximum diameter after label attachment x Pi) / 2 Notch length in the bending direction ≦ (Maximum length in the label height direction - element Battery body length in height direction)/2
