چکیده انگلیسی
The FeVO4 nanoparticles are synthesized by a new and facile electrostatic spray assisted coprecipitation method. The effects of calcination temperature and crystal structure on electrochemical properties are discussed. X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy, nitrogen adsorption-desorption isotherms and galvanostatic cell cycling are used to characterize the structure and electrochemical performance of the FeVO4 nanoparticles. Compare to the crystalline FeVO4, the amorphous contemporary prepared by a low-temperature thermal treatment exhibits an outstanding electrochemical performance, which deliver a high initial coulombic efficiency of 80.4%, stable cycling performance with a reversible capacity of 115.6â¯mAh gâ1 after 100 cycles and high rate capacity of 89.7â¯mAh gâ1 at 800â¯mAâ¯gâ1.
