Bio‐Inspired Trace Hydroxyl‐Rich Electrolyte Additives for High‐Rate and Stable Zn‐Ion Batteries at Low Temperatures

Abstract High‐rate and stable Zn‐ion batteries working at low temperatures are highly desirable for practical applications, but are challenged by sluggish kinetics and severe corrosion. Herein, inspired by frost‐resistant plants, we report trace hydroxyl‐rich electrolyte additives that implement a dual remodeling effect for high‐performance low‐temperature Zn‐ion batteries. The additive with high Zn absorbability not only remodels Zn 2+ primary solvent shell by alternating H 2 O molecules, but also forms a shielding layer thus remodeling the Zn surface, which effectively enhances fast Zn 2+ de‐solvation reaction kinetics and prohibits Zn anode corrosion. Taking trace α‐D‐glucose (αDG) as a demonstration, the…
