technical field
[0001] The invention relates to a method according to the preamble of claim 1 for connecting two battery poles of two battery cells made of different materials. Furthermore, the invention relates to a battery unit with interconnected battery cells according to the preamble of claim 3 . Background technique
[0002] Such a method or such a battery cell is known from DE 10 2009 046 505 A1. In this known method or its battery cell, it is provided that the poles of the first battery cell and the poles of the second battery cell are directly connected to one another by means of a material-fit, force-fit or form-fit connection. In this case, the two poles of the two battery cells consist of different materials, in particular copper and aluminum. As a connection method, a welding method and a riveting method are suggested, or alternatively, two battery poles are suggested to be screwed together.
[0003] Depending on the structure, lithium-ion batteries have batt...
