Abstract
Synthesis and characterization of new Ag + ion conducting glassy systems: x [0.75AgI:0.25AgC1]: (1 – x )[Ag 2 O:P 2 O 5 ], where 0.1 1 in molar weight fraction, are reported. The present glassy electrolytes have been synthesized by melt-quench technique using a high-speed twin roller-quencher. An alternate host salt: “quenched [0.75AgI:0.25AgC1] mixed system/solid solution”, has been used in place of the traditional host AgI. The compositional dependence conductivity studies on the glassy systems: x [0.75AgI:0.25AgC1]:(1 – x )[Ag 2 O:P 2 O 5 ] as well as x AgI:(1 – x )[Ag 2 O:P 2 O 5 ] prepared identically, indicated that the composition at x = 0.75 exhibited the highest room temperature conductivity ( σ ~ 5.5 x 10 −3 S cm −1 ). The composition: 0.75[0.75AgI:0.25AgC1]:0.25[Ag 2 O:P 2 O 5 ] has been referred to as optimum conducting composition (OCC). The some basic ion transport parameters viz. ionic conductivity ( σ ), ionic mobility ( μ ), mobile ion concentration ( n ), ionic drift velocity ( v d ), ion transference number ( t ion ) and activation energy ( E a ) values have been characterized with the help of various experimental techniques. A solid state battery was fabricated and its basic cell parameters calculated.
