Anomalies of some physical properties and electrochemical performance of lithium–lead–germanate glasses

The purpose of this paper was to approach the structure–properties interrelationship of lithium–lead–germanate glasses in order i) to understand the structural mechanism responsible for the germanate anomaly; ii) to determine some physical properties such as density, optical gap energy, refractive index; iii) to find electrochemical performance of the studied glasses. The studied homogeneous glass system has the xLi2O·(100−x)·[7GeO2·3PbO] composition where 0≤x≤40mol%Li2O.
