Electrochemical Studies on Single Crystalline CuCl Solid Electrolyte

Abstract

The d‐c polarization technique, relaxation technique, and the charge transfer technique have been applied to cuprous chloride single crystals for the determinations of electronic conductivity, mobility of electronic carriers, and the double layer capacitance at interface. A method to separate the electronic charge transfer is presented. It has been shown that the redistribution of electronic carriers within the solid electrolyte in which the concentrations of electronic carriers exponentially increase with the applied potential may make a significant contribution to transient measurements involving a polarization cell. Further, ideal polarization kinetics were observed for the interface in the temperature range of 200°–300°C, because the electronic charge transfer was made negligible by selecting the proper parameters such as thickness of the electrolyte and the magnitude of the applied potential step as well as the values of the applied potentials, and , on the polarization cell.
