Abstract

Nanocomposite electrodes of cobalt (II) oxide nanoparticles (CoO NPs)/multiwalled carbon nanotubes (MWCNTs) were fabricated by a two-step process consisting of electrophoretic deposition followed by chemical vapor deposition. Results of the electrochemical analysis demonstrate that the CoO NP-bearing MWCNT electrodes could deliver reversible charge capacities of 600 and 550 mA h g-1 after 50 and 100 cycles, respectively, at the rate of 715 mA g-1. The superior cyclability is attributed to the unique self-supported one-dimensional structure of the MWCNTs and the uniformly dispersed CoO NPs that constitute these nanocomposite electrodes.
