Abstract: The electrical conductivity of (LiX) y[(Li 2O)0.6 (P 2O 5)0.4] (1-y) (X=Cl, Br, y=0, 0.1, 0.15, 0.2) glasses has been determined over a wide range of temperature and frequency by means of impedance spectroscopy. The real part of the frequency-dependent conductivity exhibits a simple power law feature, and the dimensionless frequency exponent n has been determined. The conductivity spectra show scaling behaviour when the conductivity spectra are scaled by ω/(σ dcT) and ω/ω p. The conductivity relaxation time and activation energy have been estimated from the modulus spectra. Increases of ionic conductivity values with addition of LiX content are in line with the decrease of activation energy and relaxation time. © Springer-Verlag 2010.
