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.

“…As indicated in the first discharge curve (Figure 5C), the H + insertion is ascribed to generating the voltage platform in region I. In comparison, the comparable voltage platform in region II is strongly correlated with the dominance of the Zn 2+ insertion process 27,53,54 . As demonstrated in Figure 5D, the SMM@Mo180 cathode electrode exhibits good long‐term cycling stability at 150 mA g −1 with a high Coulombic efficiency of approximately 100%, revealing that the Zn||SSM@MO180 cell is highly reversible.…”

“…CV curves at different scanning rates are depicted in Figure 5E and Figure S5A‐B. The slope of the log( i ) vs log( ν ) plot defines the b value, which offers insight about the charge storage mechanism; b value of 0.5 suggests a process is diffusion‐controlled, whereas 1.0 indicates a process is surface capacitive‐controlled 27,38,55 . From the plotting of log( i ) vs log( ν ) (Figure 5F and Figure S5C‐D), the b value of SSM@MO140, SSM@MO160, and SSM@MO180 cathodic named peak 1 is 0.871, 0.875, and 0.934, respectively, indicating that the Zn ion intercalation process is mainly controlled by capacitive type behavior.…”

Summary Manganese‐based oxides are being actively studied as cathode materials for rechargeable aqueous zinc ion batteries (AZIBs) because of their high capacity, cost‐effectiveness, safety, and eco‐friendliness. Herein, we propose a binder‐free electrode of bivalent manganese oxide with the chemical composition of Mn5O8 deposited on stainless steel as a cathode of AZIBs. Mn5O8 nanoparticles with a layered structure, which provide a facile pathway for Zn2+ ion transport and diffusion, were directly deposited on a three‐dimensional stainless steel mesh via a hydrothermal method using different temperatures. The structures of the active materials in the cathode were characterized by X‐ray diffraction, high‐resolution transmission electron microscopy, X‐ray photoelectron spectroscopy, and field‐emission scanning electron microscopy. The Mn5O8 cathode materials exhibited a high specific capacity of 254.98 mAh g−1, and simultaneously demonstrated satisfactory reversible charge/discharge and high rate performance. The Zn2+ insertion/extraction behaviors were studied in detail by cyclic voltammetry. In addition, factors that influence the electrochemical performance of the cathode, such as the phase structure and particle size of manganese dioxide, are discussed. Smaller and homogeneous Mn5O8 particles provide a large interface area and facilitate more zinc ions for diffusion, leading to improved ionic current and specific capacity.

Zinc‐ion batteries (ZIBs) are a promising alternative for large‐scale energy storage due to their advantages of environmental protection, low cost, and intrinsic safety. However, the utilization of their full potential is still hindered by the sluggish electrode reaction kinetics, poor structural stability, severe Zn dendrite growth, and narrow electrochemical stability window of the whole battery. Graphene‐based materials with excellent physicochemical properties hold great promise for addressing the above challenges foe ZIBs. In this review, the energy storage mechanisms and challenges faced by ZIBs are first discussed. Key issues and recent progress in design strategies for graphene‐based materials in optimizing the electrochemical performance of ZIBs (anode, cathode, electrolyte, separator and current collector) are then discussed. Finally, some potential challenges and future research directions of graphene‐based materials in high‐performance ZIBs are proposed for practical applications.
