Abstract
This present work discussed the ionic conductivity and ionic conduction mechanism of solid polymer electrolyte (SPE). The SPE was prepared from 2-hydroxyethyl cellulose incorporated with ammonium nitrate and plasticized with ethylene carbonate (2-HEC-AN-EC) via well-known solution casting method. All SPEs were characterized using electrical impedance spectroscopy (EIS). It was found that the ionic conductivity at elevated temperature obeys Arrhenius rule. The plot of frequency exponent s against temperature shows that the correlated barrier hopping (CBH) was the best model to explain the ion conduction through 2-HEC-AN-EC SPE.
