💡 Novelty & Significance:
The novelty lies in coupling thermodynamic and kinetic regulation of water structure via a hydrogel electrolyte that disrupts hydrogen bonding while restricting molecular dynamics. This simultaneously suppresses ice nucleation and hydrogen evolution, enabling wide-temperature zinc batteries. Significance: over 8000 h symmetric-cell stability, 15,000 full-cell cycles, and reversible operation at −30°C, offering a design strategy for extreme-condition aqueous batteries.
