Dual‐Functional Additive Regulating Zn2+ Solvation Structure and (002) Plane‐Oriented Deposition for Dendrite‐Free Zn Anodes

Advanced Functional Materials, EarlyView.
Sulfosalicylic acid (SSA) is introduced as a bifunctional additive for Aqueous zinc‐ion batteries. SSA reconstructs the solvation structure of Zn2+ through the synergistic effects of its multiple functional groups, suppressing side reactions while selectively promoting Zn (002) deposition to prevent dendrite formation.
