A traction battery module has a housing body having four side walls and two end walls, and a plurality of cell elements which are arranged in the housing body, are arranged parallel to one another and parallel to two of the four side walls and are combined to form a cell element stack. A respective holding frame is positioned at the two end-side longitudinal ends of the cell element stack, on which holding frame the longitudinal ends of the cell elements are held such that the cell element stack is spaced apart in all four transverse directions from the four side walls. Each holding frame has a spring arrangement on its spring side facing a side wall and does not have a spring arrangement on its fixed side opposite the spring side. The holding frame is pressed by the spring arrangement onto the side wall assigned to the fixed side.
