“…The mechanisms for Zn 2 + storage in V 2 O 3 also differed in previous studies, given the different morphologies and electrolytes that were used. [13,20,[24][25][26][27] One possible mechanism is a phase transformation with the oxidation of V 2 O 3 to V 2 O 5 after the electrochemical activation in the initial several cycles by combining the appropriate selection of electrolyte and V 2 O 3 nanoparticles to realize a reversible Zn 2 + intercalation/ deintercalation. [24][25][26] Another possibility is the reversible insertion/extraction of Zn 2 + into the tunnel of V 2 O 3 by H 2 O intercalation to expand the galleries.…”

Aqueous Zn-ion batteries (ZIBs), with the advantages of low cost, high safety, and high capacity, have great potential for application in grid energy storage and wearable flexible devices. However, their commercial application is still restricted by their inferior long-term cycling stability, Zn dendrite formation, and the decomposition of aqueous electrolyte. In this study, a Zn j Zn(CF 3 SO 3 ) 2 + LiTFSI j V 2 O 3 @C cell is constructed to address the above issues. The V 2 O 3 @C electrode can be fully oxidized into amorphous V 2 O 5 @C simultaneously with Zn 2 + and H 2 O co-insertion. The cell delivers a high specific capacity of more than 240 mAh g À 1 at 3 A g À 1 , with extraordinary coulombic efficiency and capacity retention. The excellent electrochemical performances are attributed to synergistic effects between the V 2 O 3 @C electrode and the water-in-salt electrolyte with enhanced stability and improved interface reaction kinetics. Systematic improvements of this architecture indicate much promise for application.

Comprehensive Summary Rechargeable aqueous zinc‐ion batteries (ZIBs) featuring low cost, superior performance, and environmental benignity have attracted dramatic attention as a promising alternative energy storage system to lithium‐ion batteries. Nevertheless, the development of ZIBs is still hindered by the limited selection of cathode materials due to the large solvation sheath and charge density of Zn2+. Two‐dimensional (2D) materials have attracted extraordinary attention owing to the unique layered structure bonded by weak van der Waals’ forces, which makes them promising host materials for Zn2+ intercalation/de‐intercalation. In this review, the synthesis and properties of 2D materials for cathodes in ZIBs are discussed. Meanwhile, various reports on 2D materials as ZIBs cathodes are summarized. Three key strategies to elicit improved Zn2+ storage abilities: defect engineering, heterostructure engineering, and interlayer engineering, are highlighted. Finally, this review ends with perspectives relating to the challenges and opportunities of 2D materials‐based ZIBs.

Aqueous zinc‐ion batteries (AZIBs) stand out among many monovalent/multivalent metal‐ion batteries as promising new energy storage devices because of their good safety, low cost, and environmental friendliness. Nevertheless, there are still many great challenges to exploring new‐type cathode materials that are suitable for Zn2+ intercalation. Vanadium‐based compounds with various structures, large layer spacing, and different oxidation states are considered suitable cathode candidates for AZIBs. Herein, the research advances in vanadium‐based compounds in recent years are systematically reviewed. The preparation methods, crystal structures, electrochemical performances, and energy storage mechanisms of vanadium‐based compounds (e.g., vanadium phosphates, vanadium oxides, vanadates, vanadium sulfides, and vanadium nitrides) are mainly introduced. Finally, the limitations and development prospects of vanadium‐based compounds are pointed out. Vanadium‐based compounds as cathode materials for AZIBs are hoped to flourish in the coming years and attract more and more researchers' attention.
