摘要	In order to increase the cycling performance and reversible capacity of Co3O4 electrode materials, TiO2/Co3O4 anode materials were prepared by a two-step hydrothermal method. The phase composition, structure and morphology of the TiO2/Co3O4 anode materials were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The electrode performance of the materials was tested by a battery discharge and charge tester and an electrochemical workstation. The results shows that the TiO2/Co3O4 nanostructured materials consist of a new type of nest-like nanostructure, formed by an external mechanical force. A single nest-like TiO2/Co3O4 nanostructure is composed of the monoclinic TiO2-B and cubic Co3O4 phases. The nanostructured materials have excellent electrochemical performance, with a capacity of 650 mAh/g and a current density of 33.5 mA/g after 100 cycles.
