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.

Mild aqueous Zn batteries have attracted increasing attention for energy storage due to the advantages of high safety and low cost; however, the rechargeability of Zn anodes is one major issue for practical applications. In this work, an effective approach is proposed to improve the reversibility and stability of Zn anodes using advanced acidic electrolytes. A trace amount of acetic acid (HAc) is employed as a buffering agent to provide a stable pH environment in aqueous Zn electrolytes, and thus suppress passivation from precipitation reactions on Zn electrodes. Meanwhile, tetramethylene sulfone (TMS) is introduced as the critical component to stabilize the Zn anodes in the acidic electrolyte. TMS greatly strengthens the hydrogen‐bonding network with reduced H2O activity and extends the electrochemical window of acidic electrolytes. With the optimal 3 m Zn(OTF)2 in (H2O‐HAc)/TMS acidic electrolyte (pH 1.6), the Zn electrode exhibits a coulombic efficiency of >99.8% and smooth Zn deposition. The Zn‐V2O5 full cell demonstrates ultra‐stable cycling over 20 000 cycles with a low decay rate of 0.0009% for each cycle at a negative/postive capacity ratio of 6.5. This work provides an insightful perspective to stabilize Zn electrodes by regulating the pH environment and limiting the H2O activity simultaneously for long‐life Zn anodes.

“…[ 29–31 ] This cyclic property is close to that of Zn anode modified by pH tuning strategy (600 h at 3 mA cm –2 ). [ 32 ] Even after 600 h (Figure 4a), ZnGaIn//MXene anode still exhibits a low mass‐transfer‐controlled overpotential (≈25 mV). These good electrochemical properties should be ascribed to the efficient stress‐release in the repeated plating‐stripping process.…”

Zinc anodes are promising for zinc‐based batteries owing to the high theoretical capacity (820 mAh g−1), environmental‐friendliness, and good safety, but the uncontrollable dendrites greatly hamper their practical applications. Here, a special nonmodulus liquid GaIn electrode is designed to help understand the failure mechanism of Zn anodes, demonstrating that there is a huge crystalline stress in the plating Zn anode that causes the fast growth of substantial Zn dendrites. To solve this issue, a zinc‐enriched liquid metal (ZnGaIn) anode on flexible MXene layers (ZnGaIn//MXene) is fabricated, enabling efficient release of the stress in the plating Zn anode. Moreover, owing to the presence of zinc‐based liquid metal, the nucleation energy barrier is largely reduced and meanwhile the nucleation overpotential of Zn is reduced to 0 V versus Zn2+/Zn. Thus, the as‐prepared flexible zinc‐based anode delivers a long cycle life and high rate capabilities up to 8.0 mA cm−2. As coupled with a MnO2 cathode, a full cell with ZnGaIn//MXene anode exhibits a stable and long lifespan, greatly benefiting the development of next‐generation zinc‐based batteries.
