ABSTRACT

Nanocomposite polymer electrolytes using PEO-LiCF3SO3 incorporated with nanosized SiO2 fillers have been prepared by the solution cast technique. The effects of concentration of filler on the dielectric properties of the electrolytes were studied. Conductivity is observed to increase with filler concentration with two maximas in conductivity observed at 6 wt % and 10 wt % SiO2 concentration after which the conductivity decreases. Temperature effects on the dielectric properties revealed that the electrolytes to be of the non-Debye type.
