Abstract
A thermal management apparatus and method of use, such as in a battery pack or electronic device. A thermally responsive material is disposed between two surfaces, wherein the thermally responsive material changes upon heating, to increase a thermal conductance between the two surfaces. The thermally responsive material is offset from one of the surfaces and expands upon heating to connect the two surfaces. The thermally responsive material is a phase change composite including a phase change material selected from a paraffin wax, a hydrated salt, and combinations thereof.
