摘　　要：Li Fe PO4作为锂离子电池正极材料被应用到动力电池之中,来源广泛及具有良好的循环稳定性,但是倍率性能较差及比能量不足成为限制其进一步发展阻力。磷酸锰铁锂材料工作电压高且位于通用电解液范围内,因此具有良好的应用前景。但是循环稳定性不足,有待进一步改进。Li Fe PO4 as the common materials was applied into lithium ion battery, for widely sources and splendid cycle stability. However,bad rate capacity and low energy density were the defect for blocking the development of it.High work voltage was owned by Li MnxFe1-xPO4,which lied at the voltages of electrolyte,then a favorable application prospect was owned. However, the property of cycle stability was insufficient, which needed further improvement.
