| Abstract: | Carbon nanotubes (CNTs) grown on electrospun polyacrylonitrile-based carbon nanofibers (CNFs) via chemical vapor deposition were studied in this paper. Analyses of Raman spectra and X-ray diffraction patterns revealed that incorporation of CNTs could improve the crystalline and structure integrity of the obtained CNFs/CNTs composite. About 7.4 wt% of CNTs were grown on the electrospun CNFs confirmed by thermal gravimetric analysis. The electrochemical results showed that the surface activity and the cycle retention of the CNFs/CNTs composite were enhanced due to its three-dimensional nanostructure, enhanced pore distribution, and good conductivity. The CNFs/CNTs composite offers a great potential for high-performance lithium-ion batteries as the electrode. |
