Abstract Deep eutectic electrolytes offer opportunities for tailoring solvation structure and interface chemistry in advanced batteries, but developing deep high‐performance zinc ion batteries (ZIBs) remains a challenge. Herein, multifunctional dual‐metal‐salt derived ternary (DMEEs) are designed via supporting salt strategy dendrite‐free long‐lifespan ZIBs. DMEEs constructed by trifluoromethanesulfonate (Zn(OTF) 2 ), of lithium bis(trifluoromethanesulfonyl)imide, neutral ligand N‐methylacetamide. Noticeably, with weak lattice energy not only induces the reconstruction intermolecular interactions to form pairs aggregates also tailors Zn 2+ solid electrolyte (SEI). The developed possess dual‐anion‐rich shell induce an inorganic‐rich hybrid SEI, which effectively suppresses side reactions obtains anode high reversibility. Remarkably, Zn//Zn cells demonstrate cycling stability over 3000 h, Zn//PANI full deliver no significant capacity decay after 5000 cycles at current density 5 A g −1 . This work opens new avenue design electrolytes, understanding SEI offers guidelines batteries.

Abstract The widespread adoption of aqueous Zn ion batteries is hindered by the instability anode. Herein, an elegant strategy proposed to enhance stability anode incorporating nicotinic acid (NA), additive with a unique molecule‐ion conversion mechanism, optimize anode/electrolyte interface and typical ZnSO 4 electrolyte system.

Abstract Aqueous zinc‐ion batteries have garnered significant interest due to their inherent safety, cost‐effectiveness, and high capacity. However, water molecules in the electrolyte adsorb onto surface of negative zinc electrode via hydrogen bonding dissociate into H + OH − under an electric field. This creates a local alkaline environment at interface, promoting dendrite growth, corrosion, evolution reaction. Herein, bond competition strategy for optimizing aqueous electrolytes based on low‐cost polyhydroxyl organic additive maltitol is proposed. The addition disrupts network reduces activity molecules, replacing one solvation structure [Zn(H 2 O) 6 ] 2+ . Additionally, preferentially adsorbs Zn (002) compared molecules. stable deposition crystal faces inhibits growth evolution.
