| Summary: | As a promising electrochemical energy storage system (EESS), aqueous zinc‐ion batteries (AZIBs) hold the potential to achieve energy storage with low‐cost and nonpollution merits. However, the intrinsic defects of these systems block their further development severely, including dendrite growth, structural deterioration, parasitic reactions, and sluggish charge/discharge kinetics. Herein, the application of 2D carbon‐rich materials against the drawbacks of AZIBs is introduced. Advantages of each representative 2D carbon‐rich material (i.e., graphdiyne, graphene, 2D covalent organic frameworks, 2D metal organic frameworks, and 2D conductive polymers) are thoroughly discussed, along with recent progress of AZIB cathodes, anodes, separators, and electrolytes utilizing 2D carbon‐rich materials. Finally, the features of various 2D carbon‐rich materials are summarized and several perspectives on optimization of 2D carbon‐rich materials, development of characterization techniques, and the practical use of AZIBs in the future are given.
