THERMOELECTRIC EFFECTS IN ELECTROCHEMICAL SYSTEMS - NONCONVENTIONAL THERMOGALVANIC CELLS

In the present study, the possibility of using electrochemical systems for solving the problems of direct thermoelectric conversion is considered for a number of nonconventional electrochemical couples: 'inert' electrode/macrocyclic complex with the central coordinated metal ion in different oxidation states (aqueous, aprotic organic electrolyte), 'inert' electrode/metal ion in different oxidation states (molten salt), lithium intercalate/lithium-containing aprotic organic electrolyte, semiconductor/molten salt. A comparative analysis of data on the main criteria of thermoelectric ability (Seebeck coefficient, efficiency factor, Z-factor, efficiency, etc.) confirmed that it is possible in principle to use the electrochemical systems studied in direct thermoelectric conversion devices.
