Vanadium nitride (VN) is considered to have sufficient application potential for energy storage, and in the field of aqueous zinc‐ion batteries (AZIBs), its unique in situ phase transition mechanism is conducive to solving the intrinsic low conductivity, slow kinetics, and poor cycling stability of vanadium‐based materials. In the present study, the nanoscale morphology of VN cathode materials is controlled by cationic modulation of decavanadate precursors. Among them, VN quantum dots/nitrogen‐doped carbon nanosheets (VNQD/NC), which have the prime particle size and uniform distribution on a carbon substrate, show excellent cathode performance after activation. The innovative VNQD/NC composite exhibits high discharge capacity (698 mAh g−1 at 0.5 A g−1), excellent rate performance (498 mAh g−1 at 20 A g−1), and excellent stability. The mechanism of the VNQD/NC cathode is investigated by various ex situ means, and researchers actively analyze the source of its excellent electrochemical performance. This work offers an alternative strategy for the preparation of nitride materials and provides insights into the development of high‐performance vanadium‐based cathodes for AZIBs.

The current dominance of high-energy-density lithium-ion batteries (LIBs) in the commercial rechargeable battery market is hindering their further development because of concerns over limited lithium resources, high costs, and the instability of organic electrolytes on a large scale. However, rechargeable aqueous zinc-ion batteries (ZIBs) offer a promising alternative to LIBs. They provide ecofriendly and safe energy storage solutions with the potential to reduce manufacturing costs for next-generation battery technologies. Although ZIBs face challenges, such as dendrite formation, lower energy density, and limited cycle life, they are increasingly becoming more cost-competitive and gaining market acceptance. This article explores the potential of ZIBs as a future energy source, emphasizing their advantages and the recent technological progress in utilizing zinc, which is both abundant and inexpensive. We delve into the various mechanisms employed by ZIB electrodes and discuss the latest developments in electrode materials for anodes and cathodes, as well as the essential electrolytes and separator materials required for assembling ZIBs. Consequently, with their cost-effective materials, enhanced safety, and ongoing technological advancements, ZIBs are emerging as a promising solution for reliable and sustainable energy storage.
