An efficient electrode material for high performance solid-state hybrid supercapacitors based on a Cu/CuO/porous carbon nanofiber/TiO₂ hybrid composite.

ABSTRACT: A Cu/CuO/porous carbon nanofiber/TiO₂ (Cu/CuO/PCNF/TiO₂) composite uniformly covered with TiO₂ nanoparticles was synthesized by electrospinning and a simple hydrothermal technique. The synthesized composite exhibits a unique morphology and excellent supercapacitive performance, including both electric double layer and pseudo-capacitance behavior. Electrochemical measurements were performed by cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The highest specific capacitance value of 530 F g^-1 at a current density of 1.5 A g^-1 was obtained for the Cu/CuO/PCNF/TiO₂ composite electrode in a three-electrode configuration. The solid-state hybrid supercapacitor (SSHSC) fabricated based
