Zn₃V₂O₇(OH)₂·2H₂O/MXene cathode with fast ion diffusion for highly durable zinc ion batteries.

ABSTRACT: V-based materials are considered promising candidates as cathode materials for zinc ion batteries (ZIBs). However, the inherent low conductivity of V-based compounds leads to the sluggish diffusion kinetics of Zn²⁺ and serious cycling capacity degradation of ZIBs. Herein, 1D Zn₃V₂O₇(OH)₂·2H₂O (ZVO) nanowires were grown on monodisperse 2D Ti₃C₂T _x MXene nanosheets via a facile microwave-assisted method. The introduction of Ti₃C₂T _x MXenes effectively improved the conductivity and hydrophilicity of ZVO. Furthermore, the Zn²⁺ diffusion coefficient of ZVO/Ti₃C₂T _x composites was enhanced to 10
