Solid-state synthesis of LiFePO4/C cathode material for application in Li-ion batteries

The LiFePO4/C prepared using FeC2O4.2H2O, LiOH.H2O, NH4H2PO4 and tartaric acid via solid-state reaction. Charge-discharge and electrochemical impedance spectroscopy (EIS) tests were applied to investigate electrochemical performance of the LiFePO4/C sample synthesized. The synthesis condition of LiFePO4/C was ball-milling with speed of 250 rpm. This sample had a discharge capacity of 135 mAh.g-1 at 0.1C.
