FIGS. 1A-1F comprise a plurality of separate illustrations of the cell 100. The cell is depicted in a plan view obliquely from the front in illustration A, vertically from the top in illustration B, vertically from below in illustration C and from the side in illustrations D and E.

Illustration F shows the second contact lug 107 before it was welded to the cell 100. The planar subsection 107a is illustrated in a light color and the angled-away subsection 107b, which is subdivided into the contact section 107c and the expansion section 107d, is illustrated in a dark color.

FIGS. 2A-2F also comprise a plurality of separate illustrations of the cell 100. As in FIGS. 1A-1F, the cell is depicted in a plan view obliquely from the front in illustration A, vertically from the top in illustration B, vertically from below in illustration C and from the side in illustrations D and E.

Illustration F shows the second contact lug 107 before it was welded to the cell 100. The planar subsection 107a is illustrated in a light color and the angled-away subsection 107b, which is subdivided into the contact section 107c and the expansion section 107d, is illustrated in a dark color.

The example of the cell 100 illustrated in FIGS. 2A-2F differs from that illustrated in FIGS. 1A-1F only in respect of the configuration of the second contact lug. The contact lug is not of S-shaped design, but rather of O-shaped design.
