Sodium-Ion-Conducting Polymer Nanocomposite Electrolyte of TiO 2 /PEO/PAN Complexed with NaPF 6

Abstract

A free standing transparent of state based on PEO/PAN+NaPF6 with different compositions of nano sized TiO2 in weight percent (x = 0, 1, 2, 5, 10, 15, 20) is synthesized by using standard cast technique. The homogeneous of above composition is examined by FESEM. The microscopic interaction among salt and nanoceramic filler has been analyzed by Fourier Transformed Infra-Red spectroscopy. The reduction of ion pair formation in polymeric separator is clearly observed on addition of nanofiller in the salt complex Electrical conductivity has been recorded of the prepared polymeric separator which is of the order of ∼10−4 Scm−1 after addition of nanofiller (15% wt/wt) which support the results. Electrochemical potential window has been observed of the order of ∼6V by the cyclic voltammetry results. The observed data of the prepared separator are at par with the desirable value for device applications
