Abstract

Ion transport studies of an new sodium ion conducting polyethylene oxide (PEO) basedsolid polymer electrolytes (SPEs): (1-x) PEO:xNaF where 0<x<50 wt.%, are reported. The present SPEs films have been synthesized by recently prepared by hot-press method. The highest ionic conductivity (σ ~ 4.3×10^-7 S.cm^-1) have been observed at 30 wt.% of NaF i.e. the composition: (70PEO:30NaF). This highest conducting composition is known as optimum conducting composition (OCC). Materials characterization have been studied with the help scanning electron microscope (SEM) and thermo-gravimetric analysis (TGA).Measurements of the ionic transference number (t_ion) have been made at room temperature to help understand the structure of the system's ionic nature. Activation energy (E_a) have been computed from the temperature dependent ionic conductivity studies.
