Eutectic electrolytes have emerged as promising candidates for sustainable energy storage due the advantages of economic efficiency, safety and environmental friendliness. However, slow kinetics caused by complex hydrogen-bonding interactions remain challenging problems. Herein, we propose an innovative hydrogen-bond weakening strategy to address these challenges. By introducing weak hydrogen-bond interactions to decouple zinc-ion clusters from the hydrogen-bond network, enabling rapid Zn2+ migration at the mechanism level. The optimized zinc-ion solvation structure not only significantly reduces migration energy barriers but also facilitates the formation of a robust solid-electrolyte interphase (SEI) with high mechanical strength and ionic conductivity, enabling synergistic optimization of interfacial stability and charge transfer kinetics. Consequently, the Zn//Zn symmetric cell exhibits exceptional dendrite suppression for over 2600?h, while the Zn//PANI full cell demonstrates a ～50?% capacity enhancement. Notably, this electrolyte maintains excellent cycling stability under extreme conditions (60?°C, N/P?=?4:1), outperforming conventional aqueous electrolytes. This work offers new insights into the design of deep eutectic electrolytes.
