Solid polymer electrolyte (SPE) is one of the new invention components which can replace the traditional liquid electrolyte in a conventional battery system that sometimes experience some drawbacks, specifically is a leakage problem. Solid polymer electrolyte was successfully prepared using corn starch as the host and sodium phosphate (Na 3 PO 4 ) as an ionic dopant which both of them mixed in a combined solvent of distilled water and glycerin via a solution casting technique. FTIR was confirming that the complex films were successfully prepared based on the coexistence of the material peaks (starch and Na 3 PO 4 ). The highest ionic conductivity of 4.62 x 10 − 4 Scm −1 was obtained at room temperature (303K) for the sample containing 40 wt. % of Na 3 PO 4 . Based on the results, this SPE is proposed to have great potential in current and future energy storage applications.
