Abstract
Lithium ion battery (LIB) technology is getting more and more attention for its superior electrochemical property in recent years and has begun to gradually enter the market occupying a certain part of market. The cathode conducts as an important part of LIB, its material will influence the overall performance of the battery greatly. This paper classifies and introduces multiple cathode material already basic applied commercially of LIB including LCO, LMO, Ternary Lithium Oxide (mainly introduce NCM and NCA) and LFP, showing their structure, physical property, chemical property (mainly the electrochemical property working as the cathode of LIB), synthesis in the lab and manufacturing approaches in the factory. In the end of the paper, the advantages and disadvantages of each material are summarized and the reasons why some of them have got commercial applications while other not yet are discussed. Besides, the future research directions of better the cathode material are introduced briefly.
