摘要
LiFePO4正极材料具有原料来源广泛、比容量高、工作电压适中、循环性能好和电化学性能稳定等优点,被认为是下一代锂离子电池首选正极材料。介绍了LiFePO4的橄榄石型晶体结构及主要合成工艺,讨论了针对其缺点的改性研究,并对LiFePO4未来发展方向作了展望。
LiFePO4 is considered the first choice for the next generation cathode materials of lithium-ion battery because of its advantages,such as abundant resources,high capacity,medium voltage,excellent cycling performance and electrochemical properties stability.In this paper,olivine-type crystal structure and the synthesis process of LiFePO4 is to be introduced,modification of its shortcomings is discussed,and its developing trend is also prospected.
