LiFePO4/C particles have been successfully prepared by a solid state reaction with several kinds of cooking and times of sintered. The morphology and structure of the composites are characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), and the electrochemical performances are evaluated using constant current charge/discharge tests, cyclic voltammetry and electrochemical impedance spectroscopy. It can be seen in general than higher sintered time improves electrochemical behavior but in exchange for increased particle sizes which make capacity specific decrease.
