VO 2 has gained attention as a promising cathode material owing to its favorable ion diffusion pathways and abundant valence states. However, its performance is hindered by sluggish kinetics from zinc ions, high charge density, and vanadium dissolution induced by reactive water. Herein, Cr, ion doping is utilized to modulate the local electronic structure, enhancing zinc-ion diffusion. Additionally, a carbon-coating strategy is applied to reduce vanadium dissolution from excessive water-VO 2 contact. This dual-modification approach enables VO 2...
