摘　　要：钠离子电池由于具有资源丰富、价格低廉、分布广等突出优势,引起了人们的广泛关注,并有望成为锂离子电池的替代品。近几年关于钠离子电池的研究取得了一定的成果,研究体系也得到了完善。但是钠离子的离子半径较大且动力学速率较慢,会限制钠离子在电极材料中的可逆脱嵌,进而影响电池的电化学性能。因此发展低成本、高性能、高稳定性、高安全性的电极材料是推进钠离子电池应用化的关键。本文基于钠离子电池电极材料的研究现状进行了综述,并对其今后的研究方向和应用前景进行了展望,以期对其他化学电源的研究提供新思路和手段。Sodium ion battery attracted extensive attention due to its advantages of abundant resources,low price and wide distribution,which is expected to be a substitute for lithium ion battery.In recent years,achievements have been made for sodium ion battery,and the material systems have also been optimized.However,the large ionic radius and slow kinetic rate of sodium ions have limited the reversible disinsert of sodium ions in electrode materials,which adversely affects the electrochemical performance of the battery.Therefore,new electrode materials with low cost,high performance,high stability and high safety are needed to push the application of sodium ion batteries.This article summarizes the research status of sodium ion battery electrode materials,and prospects its future research direction and application prospects,in order to provide new ideas and means for the research of other chemical power sources.
