Zusammenfassung:	Exemplary traction battery pack designs are described for use in electrified vehicles. An exemplary traction battery pack may include one or more thermal barrier structures. In some implementations, each thermal barrier structure may include both a heat exchanger portion for stabilizing a temperature of battery cells of the traction battery pack and a vacuum portion for isolating the battery cells and/or the heat exchanger portion from ambient conditions. In other implementations, the thermal barrier structure may include only the vacuum portion. The thermal barrier structure may be arranged to interface with a battery array of the traction battery pack and could be integrated as part of an enclosure assembly of the traction battery pack.
