摘　　要：锂离子电池以其工作电压高、体积小、质量轻、比能量高、无记忆效应、污染小、自放电小、循环寿命长等优点成为21世纪的理想能源材料和当前的研发热点领域。其中,LiMPO4(M=Fe、Mn)因其安全、稳定、环保、资源丰富等优点成为锂离子电池中的佼佼者,尤其是LiMn PO4有望成为解决问题的突破口。为此,综述了LiMPO4正极材料有包覆、掺杂、缩小粒径、定向生长和3D"微纳结构"五个主要发展阶段,指出合成3D"微纳结构"电极材料是当前的一个重要研究方向。Due to the advantages of high operation voltage, such as small volume, lightweight, high specific capacity, no memory effect, less pollution, low self-discharge, and long circle life, Li-ion batteries were the ideal energy materials and the researching focus in 21^st century. Moreover, by safety, stablization, environmental friendly, and abound resources, LiMPO4 （M=Fe.Mn） was turned into the excellent performer in Li-ion batteries, especially the LiMnPO4that probably become the sally port. The emerging, and the five main steps of development ： enwrap, doping, shorting particle size, orientated growth and 3D “micro-nano structure” of the LiMPO4（M=Fe、Mn）cathode materials, were reviewed. Synthesizing electrod materials with the 3D “micro-nano structure” was being an important research area.
