• electrode in a three-electrode configuration. The solid-state hybrid supercapacitor (SSHSC) fabricated based on this composite exhibits a high specific capacitance value of 330 F g−1 at a current density of 1 A g−1 with 78.8% capacitance retention for up to 10,000 cycles. At the same time, a high energy

• . For the two-electrode configuration, a symmetric solid-state hybrid supercapacitor (SSHSC) was fabricated using the Cu/CuO/PCNF/TiO2 composite as an active electrode material coated on a carbon cloth (2 × 2 cm2), PVA/H2SO4 polymer gel electrolyte, separator of polypropylene sheet.
