摘　　要：磷酸铁锂(LiFePO4)是绿色环保的锂离子动力电池正极材料。但由于材料自身电子和离子传导率差、堆积密度低等缺点,限制了其实际应用。综述了对磷酸铁锂材料改性研究的最新进展,并预测今后的发展方向。Lithium iron phosphate is a kind of ideal cathode material for lithium ion power battery, because of its good advantages such as high capacity density, low raw material cost, stabilization and safety, excellent cycling perforrnance and environmental friendliness. The intrinsic defects of poor electronic and ionic conductivity and low density have limited its application in industry. The recent related research on enhancing the properties of lithium iron phosphate was reviewed and the developing trend was simply prospected.
