Simultaneous Interlayer Expansion and Defect Engineering in Hydrated V2O5 Cathodes for Fast-Charging Aqueous Zinc Batteries
Aqueous zinc-ion batteries (AZIBs) offer a safe, scalable path to grid storage, but their progress is limited by cathode materials that exhibit sluggish Zn2+ diffusion. Commercial vanadium pentoxide (V2O5), though possessing a high theoretical capacity, inherently suffers from this kinetic limitation. Here, a water-a...
