Redox supercapacitor using polyaniline doped with Li salt as electrode

We prepared polyaniline powder doped with LiPF6 and utilized it as an electrode material in a polymer redox supercapacitor. The electrode sheet was fabricated by coating the slurry directly on a charge collector. We also compared the performance of porous polyolefin separator as supplied and the polymer electrolyte as prepared. The redox supercapacitor using the polyolefin separator exhibits ∼100 F/g specific capacitance at the initial discharge and retains ∼70 F/g after 5000 cycles, while the initial specific capacitance using the polymer electrolyte is ∼80 F/g and retains ∼60 F/g after 5000 cycles.
