Abstract

Polymer electrolytes based on polyethylene oxide complexes with conducting polyaniline (PANI) and a salt of sodium chlorate has been prepared in different weight percentage ratios. The complexation is confirmed by FTIR spectroscopy and morphology study by employing SEM. AC conductivity measurements are carried out by using LCR Q meter at room temperature. Electrochemical cell parameters for battery applications at room temperature are also determined. The composites PP₅, N₃ and N₄ show good conductivity which is due to ionic polarization and electrode polarization. Among all these composites N₃ shows highest conductivity which is also well understood through the SEM studies. PP₅ shows more conductivity than all the other composites except N₃ as because PANI when mixed with PEO gives more feasibility of matrix’s for fast mobility of ions through it easily. The samples are fabricated for battery applications in configuration of Na: (PEO: PANI: NaClO₄): (I₂ + C + sample) and their experimental data are measured using the Wagner polarization technique.
