In-situ and three-dimension carbon coated LiFe0.96Ti0.02PO4/C cathode material was synthesized in solid-state method with polyvinyl alcohol (PVA) as the carbon source and supervalent Ti4+ as doping ion. The microstructures were characterized with XRD, SEM, TEM and EDS. The electrochemical performances were investigated with cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge-discharge test. The results show that the pyrolytic carbon of PVA possesses excellent electronic conductivity and can be the best candidate for coating LiFePO4 easily in an in-situ and three-dimensional way. Through the comprehensive modification of in-situ and three-dimensional carbon coating and Ti4+ doping, the active material possesses excellent low temperature and high rate electrochemical performances without reducing its intrinsic high temperature structure stability. The discharge capacities at the rate of 0.1 C under 0 ℃ and 5 C under 30 ℃ are 128.7 mAh/g and 97.4 mAh/g, respectively.
