Embodiment Construction
[0024] Lithium-ion battery 10 includes a plurality of battery cells 12 which form a cell group 14 . A head member 16 is provided on the cell group 14 . The battery cells 12 (four battery cells are shown here as an example) have the shape of a flat cuboid, the narrow sides of which lie on the base plate 18 of the battery 10 . In alternative exemplary embodiments, the cell pack 14 can obviously have more battery cells 12 . The battery cells 12 of the cell group 14 are pressed against one another by means of the wedges 20 , 22 , a defined force acting on the mutually abutting sides of the battery cells 12 , which binds the cell group 14 tightly.
[0025] During the production of the battery 10 , the cell pack 14 is subjected to a defined clamping force by means of a clamping device (not shown), which clamps the battery cells 12 in a fixed manner. A gap is designed between the U-shaped bow 24 of the straddle-clamp cell group 14 and the side plates 26 , 28 surrounding the cell gr...
