Sodium salts dissociated in polymers are promising for use as solid electrolytes in solid-state rechargeable batteries. However, the magnitude of ionic conductivity in these systems is not high enough and needs to be enhanced for practical applications. Sodium salts complexed with Polyethylene glycol-based solid polymer electrolytes are being examined to investigate their suitability in battery applications. In the present work, we report the investigations carried out on PEG-based solid polymer electrolyte complexed with Sodium Tri-fluoro Methane Sulfonate (NaCF3SO3). The ionic conductivity profile as a function of salt concentration is investigated. An insight into the mechanism of transport of ions in the solid polymer electrolyte and its nanocomposites is obtained by the conductivity profile determined from AC impedance measurements. The addition of nanoparticles increases the ionic conductivity of the composite system by 1 to 2 orders of magnitude. This is understood as due to the adsorption of anions on to the surface of the nanoparticles which enhances the segmental motion of the polymer chains.
