Embodiment Construction

[0050] figure 1 A battery cell 10 is shown which is preferably used in the battery cell module of the invention. The battery cell 10 comprises a battery cell housing 11 , on the top side of which the terminals 14 are also provided, the surface 12 covered by the gas-containing chamber 21 is arranged. In this surface 12 there is also a vent opening 13, which can be formed, for example, in the form of a rated rupture point or an overload valve in order to allow gas to escape from the battery cells in the event of an impermissible overpressure in the battery cells 10. Core housing 11.

[0051] exist figure 2 and image 3 An embodiment of a cover 20 of a battery cell module according to the invention is shown in FIG. It can be seen that the cover 20 has a substantially rectangular dimension, wherein in the central region an air-containing chamber 21 is provided, here in the form of a concave bulge of a single layer of cover material. especially here image 3 As shown, the ai...
