Abstract this paper describes a new synthesis route to prepare LiFePO4 cathode material. The novel aspect of the synthesis is based on a critical step involving the addition of CuO powder to promote the dissolve of Fe powder in Phosphate acid solution. The materials were characterized by thermogravimetric and differential thermal analysis, X-ray powder diffraction, Scanning electron microscopy and electrochemical measurements. Results shows that the prepared LiFePO4 materials display good electrochemical performance, suggests that the synthesis route has the possibility of an easy scale-up to an industrial process.
