In recent years, with rapid development of mobile devices and electric vehicles, lithium-ion battery as an efficient and clean battery technology has attracted wide attention. Cathode material of Li ion batteries (LIBs) is the core part that determines the battery performance. This paper aims to review the research status and latest progress of cathode materials for Li ion batteries, analyze their advantages and disadvantages, and discuss their application prospects in batteries. The review includes two kinds of cathode materials which are widely used and have the best performance in commercial uses for now: lithium iron phosphate (LFP) cathode material and ternary cathode material. The structure, properties, synthesis and modification methods are analyzed and summarized. Based on the analysis of the two materials respectively, the influence factors and countermeasures on the capacity, cycling life and safety of cathode materials for LIBs are emphatically discussed, and the future development is prospected, too.
