    Abstract: A battery cell arrangement for a battery of a motor vehicle having a plurality of cylindrical battery cells, of which at least two battery cells are arranged as a pair of cells. One battery cell of the pair of cells is arranged in an axial direction behind the other battery cell of the cell pair such that a top region of the one battery cell faces a bottom region of the other battery cell. A contact element arranged between them produces an electrically conductive connection between the top region and the bottom region. A thermal insulation is arranged between the battery cells, and the insulation inhibits a heat transmission by heat radiation in the axial direction between the battery cells of the pair of cells.

    Abstract: An electrical contact element for the electrical interconnection of battery cells for battery electric vehicles includes an electrically conductive base element that is able to make electrical contact with a first pole of a battery cell and one or more electrically conductive plug-on elements that project from the base element and are able to be bent in a temperature-dependent manner. The one or more plug-on elements, at a first temperature, assume a first bending position in which they are able to be plugged onto a second pole of an adjacent battery cell in order to produce an electrical plug connection. The one or more plug-on elements, at a second temperature that is higher than the first temperature, assume a second bending position in which the plug connection between the one or more plug-on elements and the second pole of the adjacent battery cell is released.
