摘　　要：与锂离子相比,尽管钠离子半径大,嵌入与脱嵌动力学欠佳,但由于钠的储备资源丰富,成本低,可充电钠离子电池被认为是非常有发展潜力的大规模储能电池体系。目前钠离子电池电极材料的研究主要集中在无机过渡金属材料,此类材料理论比容量不高,且提升空间有限;制备工艺复杂,消耗不可再生资源,重金属的使用会造成环境污染。相比之,有机电极材料具有理论比容量高、结构可设计性强、原料丰富、绿色环保可持续的优点。因此,开发和发展高性能储钠有机正极材料是提升钠离子电池性能的关键。本文详细介绍了钠离子电池有机正极材料研究的最新进展,主要包括基于CO键反应、掺杂反应和基于CN键反应的电极材料。同时,本文还针对有机电极材料在充放电过程中出现的问题,提出了相应的解决策略。Although sodium ion has no good performance in insertion and extraction kinetics because its radius is larger than lithium ions,rechargeable sodium-ion batteries are still considered to be with a great prospect in large-scale energy storage battery system for the advantages of abundant sodium resources,low cost of mining etc. At present,the researches on electrode materials for sodium ion batteries are mainly focused on transition metal inorganic compounds. However,there are several shortcomings： the theoretical specific capacity of this kind of material is not high to be improved enough; the preparation process is complicated; the consumed resources are non-renewable and the use of heavy metals will pollute environment. Compared with inorganic electrode,organic electrode has the advantages of high theoretical specific capacity,strongly designable structure,abundant raw materials and green environmental protection etc. Therefore,one of the keys to improving theoretical specific capacity of sodium-ion batteries is to develop and popularize high-performance embedded organic cathode material. In this paper,the latest progresses of organic cathode materials for sodium-ion batteries are introduced in detail,including electrode materials based on reaction of carbon-oxygen double bond or carbon-nitrogen double bond,and doping reaction. Meanwhile,this article also summarizes some related problems such as organic electrode dissolving in the electrolyte in the process and put forward the corresponding strategies.
