摘要：
Ni-added Li3V2(PO4)(3)/graphene (Li3V2-xNix(PO4)(3), x=0.1, 0.2, and 03, LVNP) was easily synthesized by a facile sol-gel method. The addition of a graphene and Ni in Li3V2(PO4)(3) (LVP) showed the high crystallinity and influenced the morphology of the LVP particles. The effect of the addition of graphene and Ni was investigated in physical and electrochemical properties. Compared with the pristine LVP, the LVNP composite delivered a higher discharge capacity of 180 mA h g(-1) at 0.1 C-rate and better rate capability in the potential range of 3.0-4.8 V. The electrochemical impedance spectra (EIS) measurement, the resistance of LVP electrode was reduced, which can ensure the high specific capacity and rate capability. (C) 2015 Elsevier B.V.
