1. A cooling structure for a vehicle battery cell assembly, the cooling structure comprising:
a receptacle including a thermally-conductive floor;
at least one first thermally conductive structure positioned in an interior of the receptacle and in direct physical contact with a first side of the floor;
at least one second thermally conductive structure positioned in direct physical contact with and overlying the at least one first thermally conductive structure and structured to physically separate a battery cell assembly from the at least one first thermally conductive structure when the battery call assembly is positioned in the receptacle interior and
a coolant conduit in direct physical contact with an exterior of the receptacle along a second side of the floor opposite the first side of the floor.
