Carbon-coated Li_2FeSiO_4/C cathode materials have been synthesized through a modified ball-milling process. The physical characterizations of Li_2FeSiO_4 were conducted by using X-ray powder diffraction, field-emission scanning electron microscopy and transmission electron microscopy techniques. Field-emission scanning electron microscopy and transmission electron microscopy images revealed that Li_2FeSiO_4/C consists of nanosized particles coated with an amorphous carbon layer. The electrochemical performances of Li_2FeSiO_4/C cathode materials were evaluated through fully assembled lithium batteries via cyclic voltammetry, charge/discharge test and electrochemical impedance spectroscopy. The Li_2FeSiO_4/C cathode materials showed a much improved electrochemical performance in terms of higher specific capacity, better cycling performance and less charge transfer resistance than that of the pristine Li_2FeSiO_4.
