LiMn2O4 and LiMPO4 can be used as cathode materials of power battery by judging the security of power lithium ion battery cathode material. Recent progresses on LiMn2O4 and LiMPO4 cathode materials are reviewed. Emphasis is placed on the generalization and discussion between synthesis, structures and properties of the cathode materials. At present, the LiMn2O4 is the mainstreaming cathode material for power lithium ion battery. However, the LiMPO4, especial the Li3V2(PO4)3, is the trend of development for power lithium ion battery cathode materials in long term.
