Published: May 9, 2024

Abstract Introducing N atoms in vanadium oxides (VO x ) of aqueous Zn‐ion batteries (ZIBs) can reduce their bandgap energy and enhance electronic conductivity, thereby promoting the diffusion Zn 2+ . The close‐packed oxynitride (VON) generated often necessitates intercalation water molecules for restructuring, rendering it more conducive zinc ion intercalation. However, its dense structure causes structural strain formation by‐products during this process, resulting decreased electrochemical performance. Herein, carbon‐coated porous V 2 O 3 /VN nanosheets (p‐VON@C) are constructed by annealing metal‐organic framework an ammonia‐contained environment. designed p‐VON@C efficiently converted to low‐crystalline hydrated N‐doped VO subsequent activation while maintaining stability. This is because heterojunction abundant oxygen vacancies alleviate molecule intercalation, accelerate rate. Carbon coating beneficial prevent from sliding or falling off cycling process. Profiting these advantages, activated cathode delivers a high specific capacity 518 mAh g −1 at 0.2 A maintains retention rate 80.9% after 2000 cycles 10 work provides pathway designing high‐quality ZIB cathodes.
