Abstract

The paper describes the synthesis and the properties of LiFePO ₄ cathode material prepared by a novel modified solid-state reaction. The novel aspect of the synthesis is based on the addition of a growth inhibitor (citric acid) to the precursor. The citric acid addition does not affect the structure of the cathode but considerably improves its electrochemical performances because small particle size powders are obtained. A cell discharged at 17 mA/g was able to deliver a specific capacity of 167 mAh/g with good capacity retention. EIS experiments verified that the charge transfer Has been improved compared to the sample prepared by the conventional solid-state reaction.
