    Na2O Doped Solid State Battery Electrolytes: Preparation and Electrical Characterization
    (University of North Bengal, 2024-03) Ram, Rakesh; Bhattacharya, Sanjib
    Na2O doped glassy electrolytes have been developed to explore their electrical transport behaviour at ambient temperature. The electrical conductivity (mixed conduction) has been studied in the light of both frequency as well as temperature. In the low frequency range, the diffusional motion of Na+ ions is expected to be the possible reason for a flat conductivity. It is also noted that the conductivity shows dispersion near the high frequency regime. The DC conductivity ( dc) and hopping frequency have been extracted from the best fitted plots of experimental data. The thermally active nature of electrical conductivity data have been studied to establish the dynamics of charge carriers via hopping conduction in sodium oxide glassy systems. Negligible small difference in pathways in the I-V characteristics in both the directions should make a sense for their applications for new generation battery-electrolyte.
