摘要：

The CuV2O6 cathode material was successfully synthesized using the NH4VO3 and the alkaline copper carbonate (CuCO3 center dot Cu(OH)(2)center dot xH(2)O, malachite) as the starting reagents by a citrate sol-gel route. The structures and electrochemical properties of CuV2O6 synthesized at different temperature were characterized by X-ray diffraction (XRD), thermogravimetry/differential thermogravimetry (TG/DTG), scanning electron microscopy (SEM) and electrochemical measurements. The results showed that the sample prepared at 550 degrees C had small particle size, and thus revealed higher initial discharge capacity (403 mAh g(-1)) and better cycle performance than that prepared by the conventional solid-state method.
