摘　　要：锂离子电池(LIB)近年来受到了广泛的关注,与其他可充电电池相比,锂离子电池LIB具有更高的能量密度、功率和效率。正极作为LIB的关键部件,其特性会显著影响LIB的性能。本文分类综述了一些锂离子正极材料,包括一元、二元、三元金属锂氧化物和磷酸亚铁锂正极材料,并对其优缺点进行了介绍。此外,本文还对已商业化的正极材料物性数据和具有商业化应用前景的正极材料进行了系统评价。最后,总结了各类正极材料的优势和缺陷并讨论了未来的发展和挑战。Lithium-ion battery(LIB)has received considerable attention in recent years,mainly because LIB has higher energy density,power and efficiency compared with other rechargeable batteries.The cathode material plays an important role in determining the LIB performance(e.g,capacity,thermal stability,and potential)and is the main part of LIB system.This paper presents a systematic classification of LIB cathode materials,including mono-,binary-,and ternary-based lithium metal oxide and lithium iron phosphate cathode materials,and the advantages and disadvantages of these cathode materials are systematically reviewed.The physical properties of commercialized cathode materials are compared and evaluated for potential commercialization.Finally,the advantages and disadvantages of each cathode materials are summarized,and the challenges and prospects of cathode materials for the future application are discussed.
