An aqueous vanadium complex for the superior electrolyte of a thermo-electrochemical cell

Abstract

The Seebeck coefficient of a thermo-electrochemical cell consisting of vanadium complexes reaches −3.2 mV K⁻¹ in water and −3.8 mV K⁻¹ in a mixed solvent. The solvation entropy of the proton achieves a high S_e. The ZT and electrochemical cooling effect outperform those of the benchmark electrolyte, [Fe(CN)₆]^3−/4−.
