The effect of pressure on the ionic conductivity of a lithium fast ion glass of chemical formula (B<SUB>2</SUB>O<SUB>3</SUB>) <SUB>5</SUB> (Li<SUB>2</SUB>O) <SUB>3</SUB> (LiBr) <SUB>2</SUB> has been measured at pressures from 5 to 24kbar at a fixed temperature of 326°C and from 200 to 500°C at a pressure of 5kbar. Complex impedance plots were used to model the equivalent circuit. It was found that two parallel RC circuits in series gave a satisfactory description of the data. One of these resistances was found to remain constant with pressure increase while the other increased monotomically. The activation energy for this process at 5kbar was found to be 0. 77eV. Our data are broadly in line with our predictions based on a modified random network model for the glass structure.
