Li2O-B2O3-P2O5 glasses with high lithium content were analysed by electrical characterization. The electrical conductivity increase with Li content and exhibits a maximum value of 1.2$ imes$10-4S/cm near B2O3/P2O5=1 at 15$0^{circ}C$. Glass transitiion temperature increased with conductivity. Concentration of charge carrier and distribution of relaxation time were independent of temperature. In this system the variation of conductivity with the composition was depend on mobility of lithium ion. Basically, it is attribute to primitive activation energy. Enhancement of conductivities was related to be formation of (B-O-P)-, di-, and metaborate group, which give additional available sites for Li+ diffusion.
