摘要

Glasses of series 40Li(2)O: (40 - x)B2O3: 20SiO(2): xLi(2)SO(4) have been synthesized. The T-g, density, ionic conductivity, ionic transference number and FTIR of these glasses were studied. It was observed that with Li2SO4 addition, the T-g and density of these glasses decreased, while the ionic conductivity increased. There is a good correlation among T-g , density and electrical conductivity results. Ionic transference number suggest that glass samples studied in the present work are predominantly ion conducting in nature. The FTIR results also support the observed results of ionic conductivity with Li2SO4 addition. Among the glass samples studied, the maximum conductivity of 1.46 x 10(-2) S/cm at 523 K is exhibited by the glass sample 40Li(2)O: 32.5B(2)O(3): 20SiO(2): 7.5Li(2)SO(4). This glass composition has the potential for being used as a solid electrolyte.
