Waste heat recovery with thermo-electrochemical cells is limited by their low power and conversion efficiencies. Here we explore ionic liquid electrolytes mixed with multiwall carbon nanotubes (MWCNTs) as alternative electrolytes for thermo-electrochemical cells. The results show that, upon addition of MWCNTs, the combination of interfacial polarization and ion pair dissociation reduces mass transfer resistances and enhances the power of thermo-electrochemical cells at low weight percentage of MWCNTs by up to 30%. This occurs in spite of reduced open circuit voltage due to percolated networks.
