In the present work, polyethylene oxide (PEO) doped with NaI and EMIm-TCM solid polymer electrolyte was prepared using the solution caste technique and characterized by various characterization tools. FT-IR and XRD measurements of highly conducting ILSPE showed the perfect complexation of IL with polymer. POM shows the reduction of crystallinity in polymer electrolytes by doping of ionic liquid which assists in the conductivity enhancement. The maximum conductivity was achieved at 8 wt% of 4.24x10-5 Scm-1. tion measurements show that the polymer electrolyte system is predominantly 88% ionic in nature while LSV affirms that the stability of polymer electrolyte up to 3.3.V. Furthermore, the porous structure and microcrystalline behavior of activated porous carbon material was characterized using SEM and XRD which confirms the adequate synthesis of APC material. The fabricated EDLC device shows a high specific capacitance of 115 F/g using CV. The GCD curve showed specific energy, power density, and coulombic efficiency of 12.2 Wh/kg, 2200 W/kg, and 69% respectively which is very promising for our EDLC device.
