Engineering the structural and electronic properties of VO2 through Fe substitution for high-performance aqueous zinc-ion batteries
Rechargeable aqueous zinc-ion batteries (AZIBs) are gaining attention for large-scale energy storage owing to safety and low cost. Among the numerous cathodes for AZIBs, VO 2 is a promising candidate due to its tunnel-like structure and high theoretical capacity; however, its practical application is limited by its...
