摘要

Cobalt vanadium oxides (CoV2O6 and Co2V2O7) have been one-step synthesized by a soft chemistryroute without any templates. The as-prepared materials were characterized by a variety of analyticaltechniques, including X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energydispersive X-ray spectroscopy (EDS), Fourier-transform infrared spectroscopy (FT-IR). The XRDpatterns showed that the as-prepared materials are of high crystallinity and high purity. The SEMimages showed that the Co2V2O7 material is very uniform and well-separated, with diameters around 1um. The electrochemical performances were also investigated and the results show that the CoV2O6-1 material can deliver a high initial discharge capacity of 1243 mAh g at the current density of 20 mA-1 -1g and the Co2V2O7 material exhibits a high initial discharge capacity of 949 mAh g even at a large-1 current density as high as 500 mA g .
