摘要
电动汽车已成为未来汽车的主要发展方向之一,动力电池是电动汽车的核心部件,动力电池技术则是电动汽车发展的核心技术.总结了传统锂离子电池正极材料的优缺点,及对它们的改性研究,着重介绍了LiFe-SiO4、LiVPO4F、Li3V2(PO4)3和纳米正极材料的研究现状和性能改进方法,并对其发展方向进行了展望.
Electric vehicles have become one of main development directions for future vehicles. Power bat- tery is the core part of electric vehicles and battery technology is the core technology for the development of electric vehicles. This paper summarizes the advantages and disadvantages of traditional lithium-ion battery cathode materials and describes research in their modification. The research status and methods of improv- ing performance of cathode materials for LiFeSiO4, LiVPO4 F, Li3 V2 （PO4 ）3 and nano-materials used in lith- ium-ion batteries are mainly reviewed. The development prospect of these nano-materials is also proposed.
