Abstract

Abstract Aqueous Zn batteries hold great promise for large‐scale energy storage due to their high energy density, safety, and cost‐effectiveness. Electrolyte composition directly affects Zn anode stability, and additive engineering is an attractive and cost‐efficient strategy to suppress dendrite growth and inhibit side reactions. Unlike conventional single‐component additive strategies that offer limited effectiveness and targeted control, this work presents a novel synergistic dual‐additive (SDA) strategy that collaboratively modulates the electrical double layer (EDL). The fine‐tuning of hydrophobicity enables molecules to function as either water repellents or hydrogen bond disruptors, granting them the…
