Aqueous zinc-ion batteries ( AZIBs) have a broad application prospect in large-scale energy storage field with low cost, high safety and high environmental friendliness characteristics. At present, the cathode materials which have attracted much attention have become the research hotspot. Manganese-based compound is one of the most promising cathode materials in the market due to the advantages of abundant resources, environmental friendliness and low price. In this paper, the structural characteristics of different manganese compounds and manganese-based AZIBs involved four kinds of energy storage mechanisms in the charging and discharging process are reviewed in detail, and the existing problems and optimization strategies of AZIBs manganese-based cathode materials are discussed. Finally, the possible research direction of AZIBs cathode materials is proposed, which is expected to play a certain role in the development of AZIBs.
