Na2O Doped Solid State Battery Electrolytes: Preparation and Electrical Characterization

Abstract

Present work explores the development of Na2O doped electrolytes and their conduction behavior. Electrical transport behavior (mixed conduction) of as-developed electrolytes has been investigated with respect to frequency and temperature. A nature of flat conductivity in the lower frequency window may be caused due to diffusional motion of Na+. It is also noted that the conductivity shows dispersion near the high frequency regime. Electrical conductivity has also been analyzed with respect to temperature to explore their thermally activated nature. A little bit of difference in trajectories of current-voltage characteristics in both directions should make sense for their applications in the sectors of battery-electrolytes.
