摘要：

Carbon-enriched Li0.98Mg0.02FePO4 compounds were prepared by a novel modified solid-state reaction method. Citric acid added to the precursors works as a particle size growth inhibitor as well as a carbon source. Electrochemical evaluation of the Li0.98Mg0.02FePO4 reveals a lithium insertion plateau around 3.4 V vs. Li together with a specific capacity of over 160 mAh/g at the C/20 rate. Differential capacity data confirm the two-phase nature of the insertion reactions as well as outstanding ionic reversibility.
