INVESTIGATION OF SOL-GEL ROUTE IN THE SYNTHESIS OF LITHIUM ION CONDUCTING GLASSES

Lithium ionic conducting {(0.6)Li2O-(0.4)[xB(2)O(3) + (1 - x)SiO2] x = 0.0 to 0.7 in steps of 0.1} glasses are synthesised through the sor-g el route. The monolithic form of gels are obtained with rich silica co ntent. The prepared compounds are characterised by XRD, IR and particl e size data. Electrical conductivity measurements are made at ambient as well as at higher temperatures. The activation energy (E(2)) for th e migration of lithium ion in the sample is obtained from the slopes o f log (sigma T) vs. 1000/T plot. The observed variation in the conduct ivity with the formers composition is explained qualitatively by using the existing model.
