Abstract: LiVOPO4@C composite were prepared by in-situ coating technique using LiVOPO4 and tributyl borate as raw materials. The microstructure, surface morphology and electrochemical properties were characterized by various electrochemical methods in combination with elemental CHNS analysis, N2 adsorption-desorption isotherm measurements, X-ray diffraction(XRD) and scanning electron microscope(SEM) and transmission electron microscopy (TEM). It is found that the porous carbon layer is coated on the surface of LiVOPO4 due to the pyrolysis of tributyl borate. The existence of boron inhibits vanadium in LiVOPO4 reduction from V4+ to V3+ to form Li3V2(PO4)3 as impurity, assuring the information of pure LiVOPO4@C composite. The porous carbon offers commodious channels for lithium ion to transfer in the electrode materials, improves the electric contact between the electrode particles, prevents the LiVOPO4 particles from aggregation, decreases the polarization of cell and thus improves the electrochemical properties of LiVOPO4 effectively. The electric conductivity of the LiVOPO4@C composite with a shell thickness of 8 nm is more than 1.35×10-8 S/m. The first discharge capacity of the LiVOPO4@C composite at 0.2C is146.0mAh/g and 98.8% of the discharge capacity is distained, while 96.25% of the discharge is distained cycling at 1.0C for 50 times.
