LiFePO4 compound was prepared by a modified protocol of solid state reaction method. Analysis of the structure and morphology of the synthesized material shows that the used protocol of synthesis can lead to the formation of a product with a relatively good purity and an average particle size of about 200 nm. The reduction of the particle size of LiFePO4 by the modified protocol leads to much better electrochemical performances than those of LiFePO4 prepared by classical protocol of solid state reaction. The use of this modified protocol may provide an easy way for industrial production of LiFePO4 cathode material in the lithium ion batteries.
