摘要: 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 exhibits unique morphology excellent supercapacitive performance, including both electric double layer pseudo-capacitance behavior. Electrochemical measurements were performed cyclic voltammetry, galvanostatic charge-discharge electrochemical impedance spectroscopy. highest specific capacitance value of 530 F g-1 at current density 1.5 obtained for the Cu/CuO/PCNF/TiO2 electrode in three-electrode configuration. solid-state hybrid supercapacitor (SSHSC) fabricated based on this high 330 1 78.8% retention up to 10,000 cycles. At same time, energy 45.83 Wh kg-1 power 1.27 kW also realized. developed material provides new insight into ways enhance properties supercapacitors, synergistic effect porous nanofibers, metal oxide nanoparticles, which together open opportunities storage conversion applications.
