Thermoelectric properties of high-conductivity solid electrolyte KAg4I5

Abstract
Measurements of thermoelectric power on a high-conductivity solid electrolyte KAg4I5 are reported at different temperatures. It is concluded that the thermoelectric voltage is due to the mobility of Ag+ ions. The thermoelectric power depends upon the temperature difference at the two ends of the sample, electrode material and the thermal history of the sample. A reaction resulting in a nonstoichiometry at temperatures below 40°C is evidenced.
