Redox additive aqueous polymer gel electrolyte for an electric double layer capacitor

Author affiliations

Abstract

A hydroquinone mediated PVA–H2SO4 gel electrolyte (PHHQ) and activated carbon from bio-waste were prepared for supercapacitor fabrication. PHHQ delivered a higher capacitance (941 F g−1 at 1 mA cm−2) and energy density (20 Wh kg−1 at 0.33 W g−1) than the PVA–H2SO4 gel electrolyte (425 F g−1 at 1 mA cm−2, 9 Wh kg−1 at 0.33 W g−1).
