As potential candidates for large‐scale energy storage systems, aqueous zinc‐ion batteries (AZIBs) have attracted more and more attention from researchers and investors. Tremendous efforts have been devoted to develop high‐efficient cathode materials for improving comprehensive performances of AZIBs. Recently reported inorganic‐organic composite (IOC) cathode materials exhibited excellent electrochemical performance and were generally superior to corresponding inorganic or organic cathode materials. This paper presents a timely review on recent progresses and challenges in IOCs for AZIBs. Preparation strategies of IOCs have been elaborated and categorized, recent advances and main working mechanisms of IOCs are exhibited with a focus on the analysis methods for mechanism studies, outlooks and challenges of IOC cathodes for AZIBs are outlined to guide their future development.
