The demand for safer batteries is growing rapidly due to fire incidents in electronic devices that use Li-ion batteries. Zn-ion are among the most promising candidates replace because they a water-based electrolyte and not explosive. However, suffer from persistent corrosion dendritic crystal formation during charge–discharge process, which decrease their reversibility hinder commercial usage. Extensive research has been conducted address these issues, but there significant limitations high process time costs. In this study, modulation of Zn–electrolyte interface overcome challenges attempted using acetamide-derived thioacetamide (TAA), surface modifier used electroplating. TAA undergoes hydrolysis an aqueous solution produces weakly acidic byproducts sulfide ions. These species adsorbed onto Zn metal surface, induces uniform Zn2+ deposition, facilitates stable interfacial layer, inhibits side reactions reduced water activity.

Abstract The stability of aqueous zinc metal batteries is significantly affected by side reactions and dendrite growth on the anode interface, which primarily originate from water anions. Herein, we introduce a multi H‐bond site additive, 2, 2′‐Sulfonyldiethanol (SDE), into an electrolyte to construct sieving‐type electric double layer (EDL) hydrogen bond interlock in order address these issues. On one hand, SDE replaces H 2 O SO 4 2− anions that are adsorbed surface, expelling O/SO EDL thereby reducing content at interface. other when Zn 2+ de‐solvated interface during plating, strong interaction between can trap EDL, further decreasing their This effectively sieves them out inhibits reactions.
