Abstract
The unstable Zn interface caused by undesired dendrites and parasitic side reactions greatly impedes the deployment of aqueous Zn metal batteries. Herein, an efficient adsorptive additive strategy is proposed to reshape the electric double layer and regulate Zn interfacial chemistry. 2-Hydroxy-4′-(2-hydroxyethoxy)-2-methylpropiophenone (Irgacure 2959) was selected owing to its strong adsorption ability, intermolecular hydrogen bonding, and exposed strong electronegative carbonyl group. The constructed self-adaptive adlayer contributes to a localized H2O, SO42–-poor environment and horizontal alignment of Zn deposits along the (002) plane, thus endowing thermodynamically stable and highly reversible Zn…
