Supramolecular Waste Heat Recovery —Molecular Assembly Meets Thermo-Electrochemical Cell—
Termoelectric conversion technology attracts much interest recently due to the demand on the efficient use of waste heat and the power supply for small sensors. Thermocell, which is also called as a thermo-electrochemical cell or thermo-galvanic cell, is an emerging candidate for the thermoelectric generator. Thermocell generates electric power by the change of equilibrium potential of a redox pair by the temperature difference. Thermocell consists of a solution of a redox pair and temperature gradient. The redox pair constructs an equilibrium potential, and the potential depends on the temperature. The state-of-the-art technology of thermocell reaches ZT value to 0.16 with CNT electrode and [Fe(CN)6]3−. Here we report the supramolecular technology for improving Seebeck coefficient of the thermocell.
Teppei Yamada obtained his B.S. and M.S. degree at The University of Tokyo in 2001 and 2003. He received his Ph.D. degree in Kyushu University in 2010. In 2003-2004, he was employed in Mitsubishi Chemical Co. Ltd, working on “Electrolyte of Lithium Ion Battery”. In 2005, he came to Kyushu University and conducted study on “Proton conductivity of metal–organic frameworks”. Since 2006, he become an Assistant Professor in Kyushu University and then moved to Kyoto University in 2010. In 2012, he moved back to Kyushu University as an Associate Professor with research focus on “Soft ionics”.
