摘要

Investigations on ion transport behavior of a new fast Ag+ ion conducting composite electrolyte system: 0.85[0.75AgI:0.25AgCl]: 0.1CeO(2) are reported. An alternate host: '[0.75AgI:0.25AgCl] mixed system/solid solution' has been used as first-phase host matrix salt, in place of the traditional host AgI, while the micron-size particles of an insulating and chemically inert CeO2 as second-phase dispersoid. The soaking time, plays important role in determining the conductivity enhancement in the composite system. The system: 0.85[0.75AgI:0.25AgCl]:0.1CeO(2) prepared at soaking time similar to 10 min. exhibited optimum conductivity: sigma(rt) similar to 1.2 x 10(-3) S cm(-1) at room temperature, which is an order of magnitude higher than that of the pure host. Structural characterization studies were performed by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). Temperature dependent measurement on the basic ionic parameters viz. conductivity (sigma), ionic mobility (mu), mobile ion concentration (n), room temperature ionic transference number (t(ion)) and ionic drift velocity (V-d) have been carried out on the system.
