This paper reports the recent developments in electrolyte containing Ionic liquids with PVDF-HFP based electrolytes for Supercapacitor applications. The electrolyte was examined using various tools. The impedance analysis shows the ionic conductivity which was found 7.7 × 10-3 S/cm. Linear sweep voltammetry was employed to determine the electrochemical stability window that is 3.91V. The ionic transference number was measured and found 97% contribution of ions indicating minimal electronic contribution to the total conductivity. POM shows a reduction in crystallinity with increasing ionic liquid content. Maximum conducting polymer electrolyte film was sandwiched between between electrodes to fabricate EDLC. EDLC delivers a specific capacitance 87.6 F/g.
