Paper Title
Employing an Electrochemical Impedance Spectroscopy Technique to Estimate the Ion Transport Parameters in Corn Starch based Solid Polymer Electrolyte

Abstract
The present work discusses the ionic conductivity and transport properties of solid polymer electrolyte (SPE). The SPE incorporates corn starch and sodium iodate (NaIO3) in various weight percentages prepared by a solution casting technique. The ionic conductivity, diffusion coefficient (D), ionic mobility (µ) and number on mobile ions (n) of SPEs were characterized by using an electrochemical impedance spectroscopy (EIS). From EIS, the highest ionic conductivity at room temperature was found to be 1.08 x 10-4 Scm-1 for 3 wt. % of NaIO3 and it is found that the ionic conductivity is dependent on the diffusion coefficient and mobility of freely charge ions.
