摘　　要：锂离子电池正极材料正在向着高比能量、长寿命、低成本、环境友好的方向发展,LiFePO4正极材料以其结构稳定、成本低、无污染等优点成为21世纪研究重点。综述了LiFePO4的研究进展。系统地阐述了其晶体结构特征及性能,以及合成方法、掺杂导电材料和控制晶体生长制备纳米粉体等对材料性能的影响。提出了下一步可能的研究方向。The cathode materials of lithium ion battery are developed towards the direction of high specific energy, long cycling life, low cost, and environmental benignity, while LiFePO4 would be most promising green battery in the 21st century for its stable structure, low cost, and no pollution. Recent research status of lithium iron phosphate, a new kind of cathode materials for lithium ion batteries, was reviewed. The crystal structures, the performance of lithium iron phosphate, the methods of preparation, the doping of multi-conductive materials and the control of crystal size to gain nano-powder were reviewed and evaluated. In addition, the study direction of this cathode material was also presented.
