The preparative methods have been devised avoid the crystallinity and to improve the conductivity in the PEO polymer solid electrolyte. Recently, enhancement of both electrical and mechanical properties are obtained by adding the various types of nano fillers like SiO2, La2O3, Al2O3, in the PEO polymer solid electrolyte.The present paper reports the synthesis of TiO2 nano particles by sol gel foam combustion route and the prepared TiO2 nanoparticles are dispersed in the PEO + LiClO4 + MoO3 to form the nanocomposite polymer solid electrolyte film by the solution casting route. Phase, structure, micro structure and elemental analysis of the TiO2 nanoparticles and nano composite polymer solid electrolyte films are respectively characterized by the X-Ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR) and scanning electron microscope with energy dispersive X-ray spectroscopy (SEM-EDX). Formation of the nanocrystalline TiO2 is confirmed from the observed XRD and FTIR results shown in fig. 2 & 3. From fig.4, SEM-EDS results confirm the presence of Ti and O elements and the nano size of the TiO2 particles. Electrical conductivity of the nanocomposite polymer solid electrolyte film is evaluated by analyzing the measured impedance data.
