Synergistic solvation-interface engineering enables dendrite-free and long-life aqueous Zn-based energy storage

Aqueous zinc-ion batteries (AZIBs) face persistent challenges in reversibility, Coulombic efficiency (CE), and long-term cycling stability, primarily due to uncontrolled dendrite growth, parasitic hydrogen evolution reaction (HER), and sluggish desolvation kinetics of hydrated Zn2 + ions. Here, we introduce a zincophobic–hydrophobic synergistic strategy by incorporating a trace amount of tiron (TR) into a 2 M Zn(OTf)2 electrolyte. Contrary to …
