| Abstract: The electrochemical performance of CoO-filled multi-walled carbon nanotubes(MWCNTs) is described. MWCNTs were purified, opened and filled with cobalt salt in one-step by wet-chemistry route. Followed by calcinations in Ar atmosphere, the salt filled in the MWCNTs decomposed to CoO subsequently. Structural characterization of the composite material by X-ray diffraction and transmission electron microscopy showed that MWCNTs were filled by discrete nano-size CoO. Compared to the MWCNTs purified by HNO3, the CoO-filled MWCNTs exhibited higher capacity and better cyclability during galvanastatic charge-discharge cycling and cyclic voltammetry (CV) tests. |
