Nature Mater [J], 2002, 2 123 A Review of Research on Cathode Materials for Power Lithium Ion Batteries Yi Tingfeng 1, Yue Caibo 1, Zhu Yanrong 1, Zhu Rongsun 1, Hu Xinguo 21. Anhui University of Technology, Maanshan 243002, China 2. Harbin Institute of Technology, Harbin 150001, China Abstract LiMn 2 O4 and Li M PO4 can be used as cathode materials of power battery by judging the security of power lithium ion battery cathode material. Recent progresses on LiMn 2O4 and Li MPO4 cathode materials are reviewed. Emphasis is placed on the generalization and discussion between synthesis, structures and properties of the cathode materials. At present, the LiMn 2O 4 is the mainstreaming cathode material for power lithium ion battery. However, the Li M PO4, especial the Li 3V 2PO4 3, is the trend of development for power lithium ion battery cathode materials in long term. Key words power lithium ion battery; cathode material; LiMn 2 O4 ; LiFePO 4; Li 3V 2PO 4 3Biography Yi Tingfeng, Ph.
