Supercapacitor electrode with a homogeneously Co(3)O(4)-coated multiwalled carbon nanotube for a high capacitance

Cobalt oxide (Co(3)O(4)) was homogeneously coated on multiwalled carbon nanotube through a simple chemical deposition method and employed in supercapacitor electrodes. SEM image indicated the uniform distribution of Co(3)O(4) nanoparticles on the surface of the multiwalled carbon nanotube. A maximum...

description Cobalt oxide (Co(3)O(4)) was homogeneously coated on multiwalled carbon nanotube through a simple chemical deposition method and employed in supercapacitor electrodes. SEM image indicated the uniform distribution of Co(3)O(4) nanoparticles on the surface of the multiwalled carbon nanotube. A maximum specific capacitance of 273 Fg(−1) was obtained at the charge–discharge current density of 0.5 Ag(−1). After 500 cycles of continuous charge–discharge process, about 88% of the initial capacity could be retained.
