Monoclinic lithium vanadium phosphate/carbon (Li3V2(PO4)3/C) cathode has been synthesized for applications in lithium ion batteries, via a rheological phase reaction (RPR) method. The sample is characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). This material exhibits high initial discharge capacity of 189 and 177mAhg−1 at 0.1 and 0.2C between 3.0 and 4.8V, respectively. Moreover, it displays good fast rate performance, which discharge capacities of 140, 133, 129 and 124mAhg−1 can be delivered after 100 cycles between 3.0 and 4.8V vs. Li at a different rate of 0.5, 1, 2 and 5C, respectively. The electrochemical impedance spectroscopy (EIS) is also investigated.
