Abstract

A composite polymer electrolyte based on polyethylene oxide (PEO): NaI system dispersed with sodium metasilicate (Na2SiO3) has been reported. The structural, thermal and electrical behaviour of the materials have been characterised using optical microscopy, X-ray diffraction, differential scanning calorimetry and impedance spectroscopy. A maximum electrical conductivity of similar to 10(-6) S.cm(-1) at 45 degrees C and 1.2 x 10(-3) S.cm(-1) at 100 degrees C has been achieved with the dispersion of the adduct, Na2SiO3. The temperature dependence of the conductivity follows an Arrhenius type plots before and after the melting temperature (T-m) of PEO in the composite materials.
