A low-temperature approach for efficient preparation of LiFePO₄ was developed. The rod-shaped [Fe₃(PO₄)₂·8H₂O + Li₃PO₄] precursor was prepared, using a mechanochemical liquid-phase activation technique, from LiH₂PO₄ and reduction iron powder. Pure LiFePO₄ was then synthesized in boiling tetra(ethylene glycol) (TEG) by polyol processing with the as-prepared precursor. In order to improve the electrical conductivity, carbon coating of the pure LiFePO₄ was carried out, using poly(vinyl alcohol) (PVA) as the carbon source. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), galvanostatic charge-discharge test and electrochemical impedance spectroscopy (EIS). The results show that well-crystallized LiFePO₄ was successfully synthesized by polyol processing at low temperature. Carbon coating significantly improves the conductive properties of LiFePO₄ and reduces charge-transfer impedance. The obtained LiFePO₄/C composite delivers specific discharge capacities of 139.8 and 129.5 mAh·g^-1 at 1C and 2C rates, respectively, displaying od cycling performance and rate capability.
