💡 Novelty & Significance:
Pre-intercalated K⁺ in K₀.₅V₆O₁₃ reinforces the vanadium framework and optimizes the confined lattice-water hydrogen-bonded network, enabling ultrafast proton transport. This proton topochemistry optimization yields 462.9 mAh g⁻¹ at 0.2 A g⁻¹, 82.3% retention over 20000 cycles, and stable pouch-cell cycling at high mass loading, offering new design principles for high-performance aqueous zinc-ion battery cathodes.
