The ionic conductivity variation in rapidly quenched lithium-containing glasses

The lithium ion conductivity of a wide variety of rapidly quenched glasses is studied both as a function of lithium ion content and with various additives which are likely to affect the microstructure of the glass. In each of the glass systems studied a maximum ionic conductivity of ≈10^?3 (ohms cm)^?1 is observed at 500 K, but this value is reached for different Li ion concentrations in different systems. Experiments with additions to the glass composition suggest that the availability of vacant interstitial sites in glasses of this type is not a limitation to fast ion conduction.
