Abstract
The ordered corn-like CuCo2O4 nanoforests were directly deposited on Ni foam by a hydrothermal/annealing method as a binder-free electrode for a symmetric supercapacitor. The ordered one-dimensional nanostructure can enhance an effective electron transport. The abundant sub-structure can be used to contribute to increasing a large number of active sites for Faradaic reactions. The binder-free loading can help to reduce the ohmic polarization during the charge/discharge process. For three-electrode configuration, the specific capacitance achieved 820â¯F/g at a current density of 2â¯mA/cm2 and long-term capacity retention of â¼94% after 1500 cycle. The symmetric device gained a high energy density of 17â¯Wâ¯h/kg at a power density of 480â¯W/kg.
