Synthesis and ionic conductivity measurement of a new potassium ion conducting solid polymer electrolytes

Abstract

Synthesis and ionic conductivity measurement of a new PEO-based K+ ion conducting solid polymer electrolytes (SPEs): (1-x) PEO: x KCl, where 0≤x≤50 in wt%., are reported. The present SPEs have been prepared by hot-press technique. Ionic conductivity measurements have been carried out with the help of LCR meter. The activation energy of newly synthesized SPE has also been calculated with the help of Arrhenius plot. Materials characterizations have been carried out with the help of DSC analysis. Ionic nature of the present SPE has been explained with the help of ionic transference number (tion) measurement.
