A thermal management system for removing waste heat from a battery cell. The thermal management system includes a unit cell that includes a vapor chamber including an evaporator surface and a condenser surface. The evaporator surface and the condenser surface are fluidly connected by a wick. The unit cell also includes a phase change material (PCM) shell encapsulating a PCM. The evaporator surface is thermally coupled to the battery cell and absorbs waste heat generated by the battery cell. The condenser surface is thermally coupled to the PCM and rejects waste heat to the PCM.
