High electrochemical performance of carbon black-bonded carbon nanotubes for electrode materials

---

Abstract.
Carbon–carbon nanocomposites were prepared by the chemical reduction of strongly oxidized multiwalled
carbon nanotubes (O-MWNTs) and acid-treated carbon blacks (A-CBs). To apply the electrode
materials, the electrochemical performance of the MWNTs–CBs was examined as a function of the CB
content. The chemically converted MWNTs–CBs were formed successfully by physical interaction during
the reduction of the functional groups of O-MWNTs and A-CBs, resulting in the conjugation of CBs onto
the MWNT surface with a high aspect ratio. The electrical properties of the MWNTs increased with
increasing CB content, resulting from the condensed MWNT networks by the CBs deposited on the
MWNTs. In addition, MWNTs–CBs showed higher current density than the pristine MWNT alone. This
suggests that the incorporation of CBs onto MWNTs could have a compacting effect on the empty pores
in MWNT networks, leading to MWNTs-based electrodes with enhanced electrochemical performance.
