Abstract
Nano composite polymer electrolytes with different concentrations of ZrO2 nanofillers added in PVDF-HFP:Mg(ClO4)2are prepared using classical solution casting technique.The incorporation of ZrO2 nanofillers into the PVDF-HFP: Mg(ClO4)2improved conductivity by making more ions available for conduction. Electrochemical Impedance Spectroscopy was used to investigate the electrical conductivity, ohmic resistance(RΩ), polarisation resistance(Rp), and Warburg impedance W to understand ion transportation behaviour. And the composition-dependent ionic conductivity was determined and the optimum found σion=6.62×10-2SCm-1 at the PSZr12. The nanocomposite polymer electrolyte is used to prepare an electro chemical cell, and its open circuit voltage is found to be1.8 V and its short circuit current is 180 mA.
