Abstract
The present work focuses on the preparation of solid polymer electrolytes
(SPEs) based carboxymethyl cellulose, CMC as host polymer doped with ammonium
chloride, AC (0–20 wt.%) as ionic dopant via solution casting technique. The ionic
conductivity and transport parameter of SPEs films were analyzed using electrical
impedance spectroscopy in the frequency range of 1 Hz–50 MHz at selected temperature
of 303–383 K. The highest ionic conductivity of 1.43×10−3 S/cm was obtained at
16 wt.% AC. Temperature-dependent ionic conductivity showed that the ionic conductivity
obeys Arrhenius rule where R2~1 and thermally assisted. Transport studies
showed that the ionic conductivity was influenced by the ionic mobility and
diffusion coefficient
