NanoEngineered High ZT Solid State Nanocomposite Thermoelectric (ssnTE) Manufacturing for Multiple Energy Generation Applications

Thermoelectrics, a technology for the direct conversion of heat into electrical energy, is a mature technology that is; however, undergoing a revolution in capability and applicability with the introduction of nanotechnology. Recent results with nanocomposite films have shown that Figures of Merit (ZT) much greater than 1.0 are possible at laboratory-scale; however a technology road map with the view towards large-volume and low-cost manufacturing processes of such TE devices has not previously been envisioned. These demonstrated results must now be transitioned into commercial applications. SMI has teamed with a leading thermoelectric (TE) research group in order to optimize and convert high-performance solid state TE materials developed at laboratory-scale into economically producible products for DOE desired products, military needs, and commercial applications in general. We propose to develop a scalable manufacturing process of large-volume and cost-effective nanocomposite TE device films with ZT values exceeding 2.0.Commercial Applications and other Benefits as described by the awardee: Conversion of heat directly to electrical energy is needed for many DOE programs and, following solar energy, will be an important part of many energy generation needs. The realization of high volume production of rugged, high-efficiency, and low-cost thermoelectric devices will have substantial positive impacts on reducing instrument size, weight and cost
