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.
