The temperature-dependent impedance spectroscopic analysis of a new superionic system 30(Cu1-xAgxI)–35(Ag2O)–35(MoO3), where x = 0.05, 0.10, 0.15, 0.20 and 0.25, was reported. Impedance and modulus analyses had indicated the temperature independent distribution of relaxation times and the non-Debye behavior of these materials. Further, the ionic transport number values determined by using Wagner’s polarization method were found to be greater than 0.96 for all these samples. The powder X-ray diffraction and differential scanning calorimetric studies carried out on these materials had clearly indicated the formation of new composite materials consisting of glassy phases as well as some crystalline phases with disordered structure. The thermoelectric power measurements had confirmed the positively charged mobile ions in these compositions.
