Abstract
We have investigated ion dynamics in several single and mixed former glasses in wide composition and temperature ranges. The ionic conductivity of these glasses depends strongly on the dopant salt content as well as on the mixed former ratio. The characteristic lengths for ion dynamics, such as mean square displacement and spatial extent of sub-diffusive motion of lithium ions, have been determined from the ac conductivity and dielectric spectra respectively. Ionic conductivity and the characteristic lengths have been correlated with the modification of the glass network structure.
