Abstract
Solid polymer electrolytes (SPEs) have been recognised as promising electrolytes to
overcome the limitation in gel/liquid counterparts. In this research, the potential of
carboxymethyl cellulose (CMC)-based SPEs was studied. Two systems, namely
System I which comprised of CMC doped ammonium nitrate (NH4NO3) salt and
System II which comprised of CMC-NH4NO3 plasticized ethylene glycol (EG) are
prepared via solution casting technique. The interactions between polymer, salt and
plasticizer in both systems are observed by FTIR analysis. The amorphousness and
thermal behaviour of both systems are obtained by XRD and TGA-DTG analyses,
respectively. The incorporation of 45 wt.% NH4NO3 salt in System I has optimized
the ambient temperature ionic conductivity to (7.71 0.04) x 10

conductivity is enhanced to (3.80 0.06) x 10

on the addition of 20 wt.% EG
plasticizer in System II. The temperature-dependent ionic conductivity for both
electrolyte systems is Arrhenian and thermally activated.
