摘　　要：层状三元正极材料以其稳定的结构及较高的理论容量等优点已成为锂离子电池正极材料中为具有发展前景的正极材料之一。传统多晶高镍三元材料制备方法制备出的材料为小晶粒团聚的二次球形颗粒,在高电压充放电时颗粒破碎导致电化学性能劣化。制备单晶三元材料可有效的解决这一问题。我们总结了近几年单晶三元正极材料的制备方法,并展望了材料的发展趋势。Layered ternary anode material has become one of the promising cathode materials for lithium ion batteries due to their stable structure and high theoretical capacity.The material prepared by the traditional polycrystalline high nickel ternary material is the secondary spherical particle with small grain aggregate.The preparation of monocrystalline ternary materials can effectively solve this problem.In this paper,the preparation and research progress of monocrystalline ternary anode materials are reviewed.
