Rate performance and kinetic properties of Li 3 V 2 (PO 4 ) 3 /C composite electrode have been investigated in this paper. The Li 3 V 2 (PO 4 ) 3 /C composite obtained via a rheological phase method displays a monoclinic structure with an average particle size of ca. 200–300nm. Electrochemical tests show this material exhibits good reversibility and excellent rate capability up to a current density of 3373mAg −1 (30C). The composite material achieves its theoretical capacity at 1C rate. The capacity loss is less than 4% from 1 to 10C. Even at the highest 30C rate, the capacity is above 100mAhg −1 . The kinetic properties of the composite electrode are analyzed by cyclic voltammetry (CV) and potentiostatic intermittent titration (PITT) techniques. The Li + ion diffusion coefficients calculated from PITT are in the range of 10 −7 –10 −8 cm 2 s −1 .
