Abstract Aqueous zinc‐ion batteries (AZIBs) attract attention due to their safety and high specific capacity. However, practical applications are constrained by Zn anode corrosion, dendritic growth, poor high‐temperature adaptability induced a strong hydrogen‐bond network in aqueous electrolytes. In this work, dual polyanionic gel electrolyte (denoted as PAM‐PAMPS‐10PD) is developed capable of withstanding temperatures (100 °C) situ polymerization. The abundant anionic groups the greatly improve 2+ transport inducing uniform deposition . Then addition high‐boiling molecular crowding agent 1,5‐pentanediol (PD) can inhibit water activity enhancing hydrogen bonding with H 2 O changing solvation structure corrosion. As result, symmetric battery using PAM‐PAMPS‐10PD be stably cycled for at least 500 h 100 °C 0.5 mA cm −2 /0.5 mAh , realizing dendrite‐free zinc anodes temperatures. Moreover, Zn–AC full has capacity retention 47.8% after 3000 cycles 4 This study provides beneficial reference design high‐performance electrolytes establishes solid foundation application AZIBs.

Abstract Disordered electrodeposition of Zn 2+ resulted in serious dendrite and hydrogen evolution reactions, greatly decreasing the energy efficiency durability aqueous zinc ion batteries (AZIBs). Herein, sodium 2‐mercaptoethanesulfonate (MSN) is proposed as a new additive to achieve induced directional on (101) crystal surface form dense uniform metal layer via cooperative effect sulfhydryl sulfonic acid groups. Different from reported additives, MSN molecules promote rapid formation adsorption layer, which accelerates its directed migration rate orderly nucleation process, achieving eliminated dendrites overpotential, far superior additives. The MSN‐introduced Zn||Zn symmetric battery displays amazing stably cycled for more than 3500 h at 2 mA cm −2 @ mAh , over 1 000 even under harsh conditions (5 5 ). Furthermore, Zn||δ‐MnO coin offers high capacity 201.5 g −1 low recession 1% during 800 cycles A higher that blank sample (121.3 56.1%), respectively, fully demonstrating extraordinary advantages contributions molecules.

Strong Dipole Inner Salt Molecule as Interface Ion Bridge for Rechargeable Aqueous Zn-Anode Batteries

The Journal of Physical Chemistry Letters, Год журнала: 2025, Номер unknown, С. 4097 - 4106

Опубликована: Апрель 17, 2025

Aqueous electrolyte additives are effective to improve the Zn anode performance, but their structural effect on electric double layer and plating remains elusive. By comparing several with varied compositions polarities, we reveal that dipole moment plays an important role in modulating electrode interface, while zincophilic functional groups crucial stripping/plating kinetics. A strongly dipolar inner salt, L-α-glycerylphosphorylcholine, is screened as a favorable additive stabilize hydrophobic surface of act Zn2+-migration bridge for fast desolvation. An aqueous 2 M ZnSO4 containing 75 mM L-α-glycerylphosphorylcholine results restriction parasitic hydrogen evolution, zinc sulfation hydroxylation, dendrite formation. Consequently, anodes achieve high Coulombic efficiency 99.8% Zn||Cu cells at 1 mA cm-2 sustain 1800 h cycling 50% depth discharge 3 cm-2. This study underscores screening mechanistic understanding salt formulate better electrolytes.
