摘要:
A hybrid of CoOOH nanorods with conductive MWCNTs is successfully prepared. Due to the introduction of MWCNTs, the diameter of the CoOOH nanorods is smaller than that of pristine CoOOH nanorods. Because of the conductive nanostructure network and smaller diameter of the CoOOH nanorods, it exhibits high capacitance, good high-rate capability and excellent cycling performance as a positive electrode for supercapacitors in a 0.5 mol L-1 KOH aqueous electrolyte. Its specific capacity is 312 F g-1 at the current density of 1 A g-1, and 182 F g-1 even at the current density of 10 A g-1. After 10 000...
