Effect of Temperature on Conductivity Performance of PEO-NaI Based Polymer Electrolytes

Abstract:

The polymer electrolyte composed of poly (ethylene oxide) (PEO) and sodium iodide (NaI) as dopant salt was prepared by using solution casting method. Effect of temperature on the conductivity performance was studied by impedance spectroscopy in the temperature range of 303 to 343K. The linear variation of conductivity with temperature suggests the Arrhenius type thermally activated process. The effect of temperature on the conductivity is discussed on the basis of number, n, mobility, μ and diffusion coefficient, D of free ions. In this paper, n, μ and D were determined using impedance spectroscopy method.
