Abstract: Aqueous zinc-ion batteries (AZIBs) show great potential in the field of electrochemical energy storage with the advantages of high safety, low cost and environmental friendliness. Prussian blue analogues (PBAs) are considered as the highly promising cathode materials for AZIBs because of their low cost and high voltage potential. Its excellent electrochemical performance and sustainable energy storage capability provide a new direction and opportunity for the development of AZIBs technology. The practical application of PBAs in AZIBs, however, is restrained by its unstable cycle life deriving from PBAs’ inherent structure deficiencies and its dissolution in aqueous electrolyte. Based on the summary of series of literature, we will comprehensively introduce the PBAs as cathodes for AZIBs in this review. Firstly, some basic knowledge of PBAs is introduced, including structural characteristics, advantages and issues. Secondly, several commonly used modification methods to improve the properties of PBAs, as well as electrolytes to stabilize PBAs, are presented. Finally, the future research directions and commercial prospects of PBAs in AZIBs are proposed to encourage further exploration and promote technological innovation.
