AbstractLiFePO4/C composite cathode material is prepared by ball milling with the assistance of EDTA chelation with using water as the media of ball mill procedure. FePO4 and LiOH are used as starting materials; a certain amount of glucose is used as carbon sources and reduction agent. The structure and morphology of the composite are characterized by X-ray diffraction and scanning electron microscopy. Cyclic voltammetry, AC impedance measurements, and galvanostatic charge-discharge and cycling performances are used to characterize its electrochemical properties. The results indicate that the performances of composites prepared by chelationassisted method are much better than common ball milling method which using alcohol or acetone as themedia of ballmill procedure. The stable discharge capacity of the prepared composite is 150 and 105 mAh g-1 at 1 and 10 C rate, respectively.
