Carbon spheres were prepared by hydrothermal method,and anode materials of NiO and Co3O4/NiO nanospheres were synthesized by using carbon spheres as templates,and compared and analyzed their electrochemical properties.The both materials were characterized and analyzed by X-ray diffraction (XRD),scanning electron microscopy (SEM),thermogravimetric analysis (TGA),Brunner-Emmet-Teller (BET) and LAND test system and electrochemical workstation,respectively.The results showed that when the current density was 100mA·g-1,the first discharge specific capacity of the Co3O4/NiO anode material was 1142mA·h·g-1,and the specific discharge capacity remained stable at about 770mA·h·g-1 after 100 cycles,and the columbic efficiency was close to 100%.The results shown that the Co3O4/NiO had good electrochemical properties,and expected to be used in the anode materials of lithium ion battery.
