💡 Novelty & Significance:
This work introduces molecular gating of water's hydrogen-bond network using 4-hydroxy-2-butanone as a dual-site modulator, fragmenting cooperative water domains and reshaping Zn2+ solvation. This topology-gated strategy suppresses proton-relay HER and alkaline passivation, enabling 99.12% Coulombic efficiency over 800 cycles and stable 1.0 Ah pouch cells, offering a new design principle for durable aqueous Zn batteries.
