Science and Engineering of Thermoelectric Materials for Waste-Heat Recovery in Automobiles

Improving the fuel efficiency of an automobile is a direct way to reduce CO2 emission.  The integration of thermoelectric (TE) devices can help achieve this goal if these are deployed in large numbers in the vehicle fleet. However, the highest-performance TE materials commercially available often contain rare elements, such as tellurium (Te).  Other high-performance TE materials contain Pb, Sb, As, or other toxic elements that may be difficult to process or deploy in a cost-effective way.

This presentation describes on-going work at Canmet Materials that explores low-cost silicide thermoelectric materials for recovering energy from automobile exhaust.  I will discuss Canmet’s effort and collaborations in developing a waste-heat recovery technology based on silicide TE materials, from material development to device design, in a multi-disciplinary approach.

Yu-Chih Tseng (B.A.Sc. 2002, Toronto; Ph.D. 2009, UC Berkeley) is a research scientist at Canmet Materials.  His present work focuses on integrating low-cost thermoelectric materials into waste-heat recovery technologies for automobiles.  Prior to his current appointment, he was with the Center for Nanoscale Materials at Argonne National Laboratory, working on nanoscale lithography for semiconductor manufacturing.
