| Abstract: | The study on polymer
gel electrolyte comprising of poly vinylidene fluoride co-hexafluropropylene
(PVdF-HFP)-polymethyl methacrylate (PMMA)-sodium iodide (NaI) with a view to
use them as electrolyte material for redox supercapacitor with
electrochemically deposited polypyrrole as electrode material has been carried
out. The fabricated gel electrolyte shows high ionic conductivity of the order
of 1.7 10-2 S cm-1 at room temperature with excellent
mechanical/dimensional stability. The redox supercapacitor has been
characterized using ac impedance
spectroscopy, cyclic voltammetry and galvanostatic charge discharge tests. The
overall capacitance values are found to be 128 mF cm-2; which is equivalent to single
electrode specific capacitance of 514 F g-1. It corresponds to energy density of
43.0 W h kg-1 and
power density of 4.0 kW kg-1.
