A battery module includes a housing including a first interior surface, a second interior surface opposite the first interior surface, and a compressed cell assembly disposed within an interior space of the housing between the first and second interior surfaces. The compressed cell assembly includes a plurality of prismatic battery cells arranged in a cell stack that includes a first end, a second end opposite the first end, and a retaining wall disposed between the first end of the cell stack and the first interior surface of the housing. The retaining wall includes a first surface in contact with the first end of the cell stack and a second surface opposite the first surface that contacts the first interior surface of the housing. The first and second interior surfaces are configured to maintain the compressed cell assembly in a compressed state having a compression force above a predetermined threshold.
