ELECTRICAL-CONDUCTIVITY OF LI2SO4-AG2SO4 SOLID ELECTROLYTES

New solid-state electrochemical sensors using Li//2SO//4-Ag//2SO//4 electrolytes have been developed for measuring SO//2 and/or SO//3 in gas mixtures. The electrical conductivities of these solid electrolytes are reported in this paper. An ac impedance technique has been used to measure the electrical conductivities of several Li//2SO//4-Ag//2SO//4 solid electrolytes. Results indicate that the electrical conductivities of the Li//2SO//4-Ag//2SO//4 solid electrolytes are much higher than those for other sulfate electrolytes. The variation in conductivity with gas composition has also been investigated.
