Abstract Zinc‐organic batteries (ZOBs) are receiving widespread attention as up‐and‐coming energy‐storage systems due to their sustainability, operational safety and low cost. Charge carrier is one of the critical factors affecting the redox kinetics and electrochemical performances of ZOBs. Compared with conventional large‐sized and sluggish Zn 2+ storage, non‐metallic charge carriers with small hydrated size and light weight show accelerated interfacial dehydration and fast reaction kinetics, enabling superior electrochemical metrics for ZOBs. Thus, it is valuable and ongoing works to build better ZOBs with non‐metallic ion storage. In this review, versatile non‐metallic cationic (H + , NH 4 + ) and anionic (Cl − , OH − , CF 3 SO 3 − , SO 4 2− ) charge carriers of ZOBs are first categorized with a brief comparison of their respective physicochemical properties and chemical interactions with redox‐active organic materials. Furthermore, this work highlights the implementation effectiveness of non‐metallic ions in ZOBs, giving insights into the impact of ion types on the metrics (capacity, rate capability, operation voltage, and cycle life) of organic cathodes. Finally, the challenges and perspectives of non‐metal‐ion‐based ZOBs are outlined to guild the future development of next‐generation energy communities.
