摘　　要：近年来,钠离子电池由于资源丰富、价格低廉等特点,逐渐成为储能领域的研究热点。然而,钠离子具有较大的离子半径和较慢的动力学速率,成为制约储钠材料发展的主要因素,而发展高性能的嵌钠正极材料是提高钠离子电池比能量和推进其应用的关键。本文详细综述了目前钠离子电池研究的正极材料体系,包括过渡金属氧化物、聚阴离子类材料、普鲁士蓝类化合物、有机分子和聚合物、非晶材料等,并结合这几年我们课题组在正极方面的研究工作,探讨了材料的结构和电化学性能的关系,分析了提高正极材料可逆容量、电压、结构稳定性的可能途径,为钠离子电池电极材料的发展提供参考。Sodium ion batteries （SlBs） have attracted increasing attention for energy storage systems because of abundant and low cost sodium resources. However, the large ionic radius of sodium and its slow electrochemical kinetics are the main obstacles for the development of suitable electrodes for high-performance SIBs. The development of high-performance cathode materials is the key to improving the energy density of SIBs and facilitating their commercialization. Herein, we review the latest advances and progress of cathode materials for SIBs, including transition metal oxides, polyanions, ferrocyanides, organic materials and polymers, and amorphous materials. Additionally, we have summarized our previous works in this area, explore the relationship between structure and electrochemical performance, and discuss effective ways to improve the reversibility, working potential and structural stability of these cathode materials.
