摘要: 钠(钾)离子电池资源丰富、成本低廉,是极具大规模应用潜力的新型电池体系。然而,受制于较大的钠(钾)离子半径,这两类电池电极材料的选择受到了极大的限制。以共轭羰基化合物为代表的有机电极材料具有柔性的骨架结构,对阳离子半径选择性小,且结构多样、理论比容量高、环境友好,基于有机共轭羰基化合物构建的钠(钾)离子电池是未来“绿色电池”发展的重要方向。本文介绍了共轭羰基化合物的分类、储钠/钾性能及机理,重点探讨了羰基化合物作为储钠(钾)材料存在的问题和改进方法。最后,总结了羰基化合物作为钠钾离子电池电极材料存在的基础科学问题、技术挑战以及竞争力,同时进一步展望了有机共轭羰基化合物的发展方向以及大规模储能领域的应用前景。

Abstract: Sodium (Potassium)-ion batteries are promising battery systems for large-scale energy storage applications owning to the low cost and resource abundance. However, the relatively larger radius of sodium (potassium) ions hinders the development of Na (K)-host materials. The organic electrode materials, especially carbonyl compounds, have been considered as one of the most promising electrode materials for SIBs and KIBs due to the structural diversity, high theoretical specific capacity and environmental friendliness. Moreover, the flexible frameworks demonstrate less restriction on the cation sizes. Therefore, constructing sodium (potassium) ion batteries based on organic carbonyl compounds are highly desirable for the next generation of "green batteries". This review offers an introduction on the classification, Na/K-storage performances and mechanisms of the organic carbonyl compounds, emphasizing on the existing problems and resolution strategies. Finally, the basic scientific problems, technical challenges and competitiveness of carbonyl compounds as electrode materials for Sodium (Potassium)-ion batteries are summarized, and the application of carbonyl-based organic electrode materials for large-scale energy storage applications are also forecasted.

Key words: sodium-ion batteries, potassium-ion batteries, organic electrode materials, conjugated carbonyl compounds
