【Abstract】 The cathode materials are the key to the development of lithium-ion batteries. After the analysis of the safety performance,cycling performance and existing issues of four kinds of cathode materials,their functions and development trend are reviewed. LiCoO2 and LiNiO2 will continue to hold the market of small batteries,while LiMn2O4 and LiFePO4 will accelerate the development of power batteries. In addition,the application of nanotechnology will bring a promising future for power batteries.更多还原
