چکیده انگلیسی
Spinel LiVTiO4/C compound is prepared via a facile sol-gel method. The structure and morphology of LiVTiO4/C are investigated by X-ray diffraction (XRD), scanning electronmicroscopy (SEM), and transmission electron microscopy (TEM). The results indicate that the LiVTiO4/C has a carbon coating layer ranging between 2 and 3 nm. Besides, the existence of VO2 improves the conductivity to some extent. The electrochemical properties of LiVTiO4/C as an anode material for lithium-ion battery are investigated for the first time. The synthesized LiVTiO4/C material exhibits a high charge capacity of 231.6 mA h gâ1 after 50 cycles at 0.02 A gâ1, with a capacity retention ratio of 96.5%. The excellent reversible capacity and excellent cycling stability indicate that the LiVTiO4/C composite has a great potential application in lithium-ion battery.
