摘要
综述了新型锂离子电池正极活性材料LiFePO4的研究概况,系统地阐述了LiFePO4的结构特征及性能;从添加导电剂或导电剂前驱体、掺杂改性以及合成纳米颗粒等方面论述了改善LiFePO4电化学性能的基本途径。
Resent research status of lithium iron phosphate, a new kind of cathode material for lithium ion batteries, was reviewed in this paper. The methods of the preparation, the characteristics of the structure and the performence of lithium iron phosphate were also stated systematically. In addition, three different ways, including adding conductive reagents or their precursor and doping with various cations to improve the electrochemical properties of lithium iron phosphate, were discussed.
