Researchers devise method to suppress thermal conductivity to improve thermoelectric materials for waste heat recovery

Green Car Congress

A new study published in the journal Nature Materials has found a way to suppress the thermal conductivity in sodium cobaltate so that it can be used to harvest waste energy, with potential applications such as automotive waste heat recovery.

Advances in the conversion efficiency of thermoelectric materials

Green Car Congress

A collaboration including researchers from Boston College, MIT, the University of Virginia and Clemson University have achieved a peak ZT (thermoelectric figure of merit) of 0.8 for the materials and possibly good enough for consideration for waste heat recovery in automotive exhaust systems. The study by Yan et al.
