New solid electrolyte system: Polycrystalline CuI-Ag<inf>2</inf>O-MoO<inf>3</inf>

Preparation, characterization (X-ray and DSC), transport number and electrical conductivity studies on the systems xCuI- (100-x)(Ag2O-MoO3) indicate that the above system acts as a fast silver ion conductor up to 50 mol% CuI. The composition 30CuI-35Ag2O-35MoO3 has the highest conductivity with σ=1.96×10-3 S cm-1 and Ea=0.28 eV. Discharge characteristic s of the solid state battery with the above conducting composition as the electrolyte show that the cell could be discharged up to 100 μA/cm2 without severe polarization. © 1992.
