FABRICATION AND CHARACTERIZATION OF SOLID-STATE CELLS USING CUI100-X-(SILVER ORTHO PYROPHOSPHATE), -LESS-THAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-60) MIXED SYSTEMS AS SOLID ELECTROLYTES/

Solid-state cells are fabricated using the best conducting composition s found in two different mixed systems, namely, CuI-Ag3PO4 and CuI-Ag4 P2O7. The discharge and polarization studies of these cells are examin ed. The open-circuit voltage and short-circuit current density exhibit ed by the two prototype systems are 639 and 635 mV and 1.2 and 2 mA cm (-2), respectively. The discharge and polarization studies indicate th at the best conducting compositions, for the two systems, i.e., (CuI)( 0.5)and(Ag3PO4)(0.5) and (CuI)(0.55)-(Ag4P2O7)(0.45) respectively,woul d act as promising solid electrolytes based on Ag+ -ion migration. Thi s is because of their excellent physical properties.
