摘要：

The need to harvest low-grade waste heat at 100-200 degrees C has attracted much attention. In this paper, the performance of thermo-electrochemical cells (TECs) with an iron triflate (Fe(CF3SO3)(2)/Fe(CF3SO3)(3)) redox couple is investigated in various organic solvents at temperatures exceeding 100 degrees C. The TECs in dimethylformamide (DMF) showed the maximum Seebeck coefficient of 1.51 mV K-1, and the maximum power density of 660 mW m(-1) was achieved using 0.5 M iron triflate in DMF at Delta T = 120 K (145 degrees C on the hot-side).
