The influence of lithium oxide concentration on the transport properties of glasses in the Li2O-B2O3-SiO2 system

Lithium ion conducting glasses in xLi(2)O-(1-x)(0.75B(2)O(3)-0.25SiO(2)) system have been obtained and studied in the x range from 50 to 67.5 mol%. The influence of the lithium oxide content on the glass transition temperature (Tg), crystallisation temperature (TA density, structure and ionic conductivity has been investigated. We establish that the anomalous behavior of the properties is observed at the point with Li2O concentration of 62.5 mol%. The value of maximal conductivity at room temperature is 3.6 . 10-6 S/cm for the glass containing 65.0 mol% of lithium oxide. (C) 2016 Elsevier B.V. All rights reserved.
