钠–有机电池以有机材料作为钠离子电池的电极，由于其丰富的钠资源和对环境友好的特点，是下一代可持续、多功能储能装置中具有吸引力的替代锂离子电池。然而，用于钠离子电池的有机物也遇到了一些问题，如氧化还原电位低、在电解质中的溶解度高、电导率低。因此，改变芳香族体系/吸附吸电子基团，构建聚合物，并结合导电基质是有效的策略。本文从功能导向设计的角度，从小分子化合物到聚合物，再到复合材料，对近年来用于钠–有机电池的有机羰基化合物进行了总结和简要讨论。本综述对羰基有机柔性电极的钠–有机电池进行了系统的综述。 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 in-corporating a conductive matrix are effective strategies. This review summarizes and briefly dis-cusses 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.
