Li3V2(PO4)(3)/C composite material with a porous structure and nano-carbon webs are synthesized through a chemical reduction-lithiation and liquid nitrogen quenching method. Li3V2(PO4)(3)/C sample was characterized by XRD, SEM, and TEM. X-ray diffraction results show Li3V2(PO4)(3) is monoclinic with a space group of P2(1)/n. SEM and TEM images indicate that the Li3V2(PO4)(3) particles are about 200nm in diameter, have porous structure, and are coated with nano-carbon webs. Electrochemical measurement results indicate that the Li3V2(PO4)(3)/C cathode exhibits high-rate characteristic and delivered a stable discharge capacity of 131.57 mA h g(-1) at 0.1 C (14 mA g(-1)), in the range of 2.6-4.5 V.
