AbstractAnodic oxidation and hydrothermal method were jointly used to prepare CuO/TiO2 negative material which was synthesized from ethylene glycol, ammonium fluoride, hydrochloric acid, cupric chloride and sodium nitrate. Morphology, element distribution, valence state, microcosmic phase composition of the samples were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD). Furthermore, the electrochemical lithium insertion properties of CuO/TiO2 were tested by the use of battery charge and discharge testing system and electrochemical workstation. The results show that there are particulates arrange the surface of the anatase TiO2 nanotube. The nanometer size was 4 nm x 10 nm. The as prepared CuO/TiO2 displays plummy electric properties of initial discharge and charge capacities of 550 and 490 mAh.g(-1) at the rate of 0.3C. respectively. After 50 cycles the reserve capacities is 320 mAh.g(-1).; Anodic oxidation and hydrothermal method were jointly used to prepare CuO/TiO2 negative material which was synthesized from ethylene glycol, ammonium fluoride, hydrochloric acid, cupric chloride and sodium nitrate.
