Lecture

High conductivity and dielectric constant Na based glass electrolyte

Wednesday (28.09.2016)
11:15 - 11:30
Part of:


Here we present a doped Na3ClO glass electrolyte with high conductivity at room temperature (10^-2 to 10^-1 S/cm) and very high dielectric constant, e'r, that can reach e'r = 10^7 at room temperature). We show how these properties vary with temperature and with time. We propose a model for the conductivity of the Na+ hopping ions as well as dipole formation and dynamics.

Finally, we illustrate the properties of the glass-electrolyte-dielectric and model in working devices.
