Abstract: In order to overcome the disadvantages of the low electrical conductivity and poor cycling stability of Co3O4 anode material, a Co3O4/C composite was obtained by the judicious selection of Co2(NDC)2DMF2 (NDC=1,4-naphthalene dicarboxylate) as precursor through a two-step calcination process. The sample was characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The content of amorphous carbon in Co3O4/C was tested by thermogravimetric analysis (TGA). As anode material for lithium-ion batteries (LIBs), Co3O4/C material showed a high reversible specific capacity, remarkable cycling performance (the specific discharge capacity was stable at 1 000 mAh·g-1 under the current density of 200 mA·g-1 even after 200 cycles) and an excellent rate performance with high average discharge specific capacities of 1 076.3, 976.2, 872.9, 783.6 and 670.1 mAh·g-1 at 100, 200, 500, 1 000 and 2 000 mA·g-1, respectively. The excellent electrochemical performance was attributed to the amorphous carbon derived from the organic ligand, which served as conductive path for easy electric charge transfer and buffer layer to slow down the volumetric stresses.
