1. A traction battery module comprising:
a housing body which is rectangular in cross section and has four side walls and two end walls,
a plurality of battery cell elements which are combined to form a cell element stack and are arranged (i) in the housing body, (ii) parallel to one another, and (iii) parallel to two of the four side walls, and
holding frames which are each respectively positioned at one of two end-side longitudinal ends of the cell element stack, wherein the longitudinal ends of the cell elements are held on the holding frames such that the cell element stack is spaced apart from the four side walls,
wherein each holding frame has a spring arrangement, a spring side that faces one of the four side walls of the housing body, and a base side that is opposite the spring side,
wherein, for each holding frame, the spring arrangement is disposed on the spring side and no spring arrangement is disposed on the base side, and
wherein, for each holding frame, the respective holding frame is pressed by the spring arrangement directly onto a first side wall of the four side walls of the housing body, wherein said first side wall faces said base side of the respective holding frame.
