Electrochemical energy storage devices will definitely play a vital role in the future energy landscape of the world. The innovation of electrode materials is a key task for the breakthrough of present bottleneck faced by electrochemical energy storage devices. Aqueous zinc‐ion batteries (AZIBs) are gaining rapid attention, and they offer tremendous opportunities to explore the low‐cost, safe, and next‐generation green batteries for large‐scale stationary storage applications. In this review, the authors aim to give a comprehensive overview and summary of the recent progresses in cathode materials for AZIBs. Broadly, the authors classify the cathode materials for AZIBs into four groups: manganese‐based cathodes, vanadium‐based cathodes, Prussian blue analogs, and organic compounds. The reaction mechanisms, zinc storage properties, and several optimizing strategies of these cathode materials are summarized. Comparative observations of the main cathode families are discussed. Moreover, the emerging challenges and future research perspectives of cathode materials for AZIBs are proposed.
