摘要	A series of Co3V2O8 nanoparticle precursors were successfully prepared by simple ion thermal synthesis under mild conditions. The optimized Co3V2O8 material with small and uniform spherical nanoparticles (similar to 50-nm diameter) was synthesized at pH 9 and 150 degrees C for 72 h in 1-butyl-3-methylimidazole bromide, while irregular large-block Co3V2O8 materials were obtained through the traditional hydrothermal method. After calcination, the synthesized material (CVO-IL) was used as an anode for lithium ion batteries and showed a high initial discharge capacity of 1528 mAh g(-1) and a reversible capacity of similar to 600 mAh g(-1) after 300 cycles, which was much higher than that of Co3V2O8 synthesized in water (CVO-W, 120 mAh g(-1)). Based on cyclic voltammetry tests and impedance measurements, it was found that the electrode reaction in this work was controlled by Li ion diffusion in the electrolyte and electrode materials for both CVO-IL and CVO-W. The Li ion diffusion coefficient of CVO-IL was much higher than that of CVO-W, which was likely due to its small and uniform spherical structure. These results, therefore, revealed the excellent electrochemical performance of CVO-IL as an anode material for Li-ion batteries. The Co3V2O8 materials prepared through ionothermal synthesis under mild reaction conditions have been rarely reported, but they should have significant potential usage in the field of lithium-ion batteries and other electrochemical systems.
