Study of lithium ion conducting glasses with Li2SO4 addition
Source abstract
Abstract
Abstract Glasses of series 40Li2O: (40−x)B2O3: 20SiO2: xLi2SO4 have been synthesized. The Tg, density, ionic conductivity, ionic transference number and FTIR of these glasses were studied. It was observed that with Li2SO4 addition, the Tg and density of these glasses decreased, while the ionic conductivity increased. There is a good correlation among Tg, 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 × 10-2 S/cm at 523 K is exhibited by the glass sample 40Li2O: 32.5B2O3: 20SiO2: 7.5Li2SO4. This glass composition has the potential for being used as a solid electrolyte.
