Ionic Conductivity of Polycrystalline Li2GexSi1-xO3 (x = 0.0~1.0)
Polycrystalline Li2GexSi1-xO3 (x = 0.0~1.0) was synthesized by solid state reaction, and its ionic conductivity was studied as a function of x in a temperature range of 500–700 K. The ionic conductivity was found to depend on x and was enhanced at x = 0.2–0.7. Furthermore, the pre-exponential factor and activation energy in the Arrhenius equation were also found to depend on x. These results suggest that lithium ionic conduction in Li2GexSi1-xO3 is strongly influenced by the structure of the framework.
