Abstract
AbstractIn this study, we have synthesized solid polymer electrolytes using polyvinyl alcohol as a host polymer that has been doped with ionic liquid and ammonium iodide. Impedance spectroscopy revealed that the increase in ionic liquid doping increased the ionic conductivity of the PVA‐NH4I complex. The crystalline nature of the polymeric films was studied using polarized optical microscopy and x‐ray diffraction. To confirm the blending ability of polymer electrolyte, Fourier transform infrared spectroscopy was also used. Finally, a supercapacitor was fabricated using the highest conducting IL‐doped polymer electrolyte which demonstrates a specific capacitance of 97 F/g with a stable efficiency.
