✦ Synopsis
Transport properties of silver ion conducting ternary amorphous solid electrolytes, XAgI-[(l -X)(yAgzO-zAs,O,)] and XAgI-[(l -X)(&&O-z&O,)] for 30 <X< 70 mol% AgI and 0.20~ (z/y) ~3.0 were characterized in a two step process to determine the highest ion conducting composition. Interesting results were obtained by the variation of Glass Former to Glass Modifier ratio (z/y) and AgI content (X). Some of the results were previously reported with z/y as a variable parameter for a constant concentration of X. The values of z/y were maintained at the best conducting compositions as derived from the previous work, and the present study reports the conduction characteristics with X as a variable parameter. The best conducting amorphous electrolytes in these two systems were used in the fabrication of solid-state batteries, and their electrochemical performance has been evaluated. A comparison of the solid-state cells with amorphous and polycrystalline electrolytes was undertaken with regard to the current discharge profiles and the cell capacities.
