The　Li3V2(PO4)(3)/C　(LVP/C)　cathode　materials　for　lithium-ion　batteries　were　synthesized　via　ethylene　glycol-assisted　solvothermal　method.　The　phase　composition,　phase　transition　temperature,　morphology,　and　fined　microstructure　were　studied　using　X-ray　diffraction　(XRD),　differential　thermal　analyzer　(DTA),　scanning　electron　microscope　(SEM),　and　transmission　electron　microscope　(TEM),　respectively.　The　electrochemical　properties,　impedance,　and　electrical　conductivity　of　LVP/C　cathode　materials　were　tested　by　channel　battery　analyzer,　the　electrochemical　workstation,　and　the　Hall　test　system,　respectively.　The　results　shown　that　the　appropriate　amount　of　water　added　to　ethylene　glycol　solvent　contributes　to　the　synthesis　of　pure　phase　LVP.　The　LVP10/C　cathode　material　can　exhibit　discharge　capacities　of　128,　126,　126,　123,　124,　and　114　mAh　g(-1)　at　0.1,　0.5,　2,　5,　10,　and　20　C　in　the　voltage　range　of　3.0-4.3　V,　respectively.　Meanwhile,　it　shows　also　a　stable　cycling　performance　with　the　capacity　retention　of　89.6%　after　180　cycles　at　20　C.
