Abstract
This study investigates the impact of HgO concentration on the dielectric properties and a.c. conductivity of the Li2O-P2O5 glass system. XRD, SEM, DSC and FT-IR spectral techniques were employed to analyze the structural variations of the samples due to the varying contents of HgO. The dielectric properties and σac were studied across wide temperature (T) and frequency (ω) ranges to understand the conduction phenomenon. The results revealed that the presence of 5 mol% HgO led to an increase in dielectric parameters and a.c. conductivity compared to those of pure sample. Variation of σac with HgO content indicated that up to 5 mol% HgO, the ionic contribution to σac was predominant, while beyond that, polaronic tunneling became more significant. Therefore, lithium phosphate glasses with 5 mol% HgO are suitable as solid electrolytes, while glasses doped with higher HgO concentrations are better suited as electrodes in ionic batteries.
