Nanoparticle oxide fillers such as SiO
2 have been previously shown to affect the properties of polymer electrolytes, especially those based on polyether-lithium salt systems. In this work nanocomposite solid polymer electrolyte films composed of polyethyleneoxide (PEO), lithium triflate (LiCF3 SO3 ) and SiO2 nanofiller (15 nm in size) have been prepared by using solution cast method. At room temperature, the sample 80PEO-20LiCF3 SO3 (wt-%) was found to have the highest conductivity of about 2·04 × 10-7 S cm-1 . The 88PEO-LiCF3 SO3 -12SiO2 (wt-%) has high ionic conductivity of about 1·28 × 10-3 S cm-1 at room temperature. The effects of concentration of filler on the dielectric properties of the electrolytes were also studied. Temperature effects on the dielectric properties revealed that the electrolytes to be of the non-Debye type. [ABSTRACT FROM AUTHOR]- Published
