Battery cell stack designs are provided for traction battery packs. An exemplary cell stack may include a thermal barrier assembly that is arranged to inhibit the transfer of thermal energy between adjacent subgroupings of battery cells of the cell stack. The thermal barrier assembly may include a bulb seal for sealing an interface between the thermal barrier assembly and a perimeter environment (e.g., a heat exchanger plate, an enclosure tray, etc.). The bulb seal may seal any leak paths between the thermal barrier assembly and the perimeter environment, thereby preventing vent gases from passing from one battery cell subgrouping to another during battery thermal events.
