摘　　要：钠离子电池作为一种新型电化学能源已经受到了广泛关注.其工作原理与锂离子电池相类似,钠元素的储量比锂元素更为丰富、成本更加低廉,因此在大规模电能存储中有着广阔的应用前景.近年来,针对钠离子电池电极材料的研究日益增多,其中关于正极材料的研究主要集中于聚阴离子以及层状过渡金属氧化物材料两大类.层状过渡金属氧化物因其导电性好,并且层状结构更加稳定而成为人们研究的热点.本文针对层状过渡金属氧化物正极材料的结构以及电化学性能进行综述,总结并分析层状材料作为钠离子电池正极材料的可行性以及目前面临的问题,为今后钠离子电池层状正极材料的研究与应用提供理论指导.As one of the novel electrochemical energy storage devises,sodium-ion battery（ SIB） has already attracted worldwide attention. The working principle of sodium-ion batteries is similar to the lithium-ion batteries.SIB has a wide application prospect in large-scale energy utilization because the amount of the sodium element is much more abundant,and the cost is significant lower than those of the lithium element. Nowadays,the studies concentrating on the electrode materials in SIB are prosperous. Furthermore,recent developments in cathode materials for SIB mainly focus on layered transition metal oxides and poly-anionic compounds. Among the various cathodes,the layered transition metal oxide material has better electronic conductivity and more stable layered structure. In this review,the structure and the electrochemical properties of the layered transition metal oxide were discussed. Moreover,this paper predicted the feasibility and the challenges of using the layered oxide materials in SIB,which may provide some suggestions on the studies and the applications of the layered oxide cathode in SIB.
