Sodium-organic batteries, which use organic materials as the electrodes in sodium-ion batteries, are an attractive alternative to conventional lithium-ion batteries for next-generation sustainable and versatile energy storage devices owing to the abundant sodium resources and environmental friendly features. However, organics used in sodium-ion batteries also encounter some issues such as low redox potential, high solubility in the electrolyte, and low conductivity. In response, altering the aromatic system/attaching electron-withdrawing groups, constructing polymers, and incorporating a conductive matrix are effective strategies. This review summarizes and briefly discusses recent organic carbonyl compounds for sodium-organic batteries from the viewpoint of function-oriented design, including function evolution from small-molecule compounds to polymers, then composites, and finally flexible electrodes. In particular, as a timely overview, carbonyl-based organic flexible electrodes for sodium-organic batteries are also highlighted for the first time.
钠离子电池使用有机材料作为电极，是下一代可持续和多功能储能设备中锂离子电池的一种有吸引力的替代品，因为钠离子资源丰富且具有环保特性。然而，用于钠离子电池的有机物也遇到了一些问题，例如氧化还原电位低、在电解液中高溶解度和低电导率。为了解决这些问题，改变芳香体系/引入吸电子基团、构建聚合物和掺入导电基质是有效的策略。本综述从功能导向设计的角度总结并简要讨论了最近用于钠离子电池的有机羰基化合物，包括从小分子化合物到聚合物、复合材料，最后到柔性电极的功能演变。特别是，作为一个及时的综述，首次强调了基于羰基的有机柔性钠离子电池电极。
