      Glass formation region was determined for the B2O3-Li2O-Li3PO4 system. Under the present experimental conditions, binary lithium borate glasses could be formed containing a maximum of 27 mol% Li2O. However, this could be increased to 36 mol% in the ternary system. Electrical conductivity was measured at temperatures ranging from room temperature to 350°C. The temperature dependence of the electrical conductivity of these glasses follows Arrhenius equation. The conductivity increased with increasingly alkali content. Maximum conductivity of the order of 10−4 ohm−1 cm−1 was obtained with the glass containing about 36 mol% Li2O at 250°C. Activation energy for conduction also varied with total Li2O content.

      More Details Abstract Fulltext PDF

      For the last few years fast ion conducting lithium glasses are being studied due to their potential use in advanced electrochemical devices. A number of glass systems containing oxides, sulphides and other lithium compounds prepared by both conventional cooling and rapid quenching techniques have been reported. In this paper we review the transport properties of lithium ion conducting glasses. The special features of the ionic conduction process have been highlighted and some experimental techniques to study transport properties have been described. Some of the common observations of the properties have been discussed and finally some important problems for future development have been pointed out.
