Impedance spectroscopy and electrochemical cell studies of Mg+2 ion conducting with dispersed ZrO2 nano filler in PVDF-HFP based nano composite solid polymer electrolytes

Nano composite polymer electrolytes with different concentrations of ZrO2 nanofillers added in PVDFHFP: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(RX), polarisation resistance(Rp), and Warburg impedance (W) to understand ion transportation behaviour. And the composition-dependent ionic conductivity was determined and the optimum found rion = 6:62 x 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.
