Enhancing Zinc Anode Reversibility through Dynamic Interface Engineering with Monolayer Hydrophobic Carbon Dots

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Янв. 2, 2025

Aqueous zinc-ion batteries promise low-cost and safe grid storage, but their practical application is hindered by poor Zn anode reversibility, primarily due to dendrite formation water-induced side reactions in the electric double layer (EDL) structure. Herein, a monolayer of hydrophobic carbon dots (CDs) was dynamically constructed at electrode/electrolyte interface. The trace-added CDs electrolyte reconstruct favorable EDL structure, suppressing inner Helmholtz facilitating desolvation hydrated zinc ions outer layer. Furthermore, CD maintained dynamic interfacial integrity during

Electrochemical Responsive Alginate Chains Rendered Sol‐to‐Gel Gradient Electrolyte towards Practical Ah‐level Zinc Metal Pouch Cell

Angewandte Chemie International Edition, Год журнала: 2025, Номер unknown

Опубликована: Март 6, 2025

Zinc metal batteries have been considered as an appealing candidate for grid-scale energy storage devices, but are hindered by the instable interface. Herein, we design a sol-to-gel gradient electrolyte through simultaneous electrochemical deposition of Zn2+ and alginate. The gelation alginate creates interface enables high ionic conductivity, where vehicular mechanism dominated transport is maintained in bulk electrolyte, while lean-water hydrogel like state created at Zn/electrolyte to reduce water activity. active undergoes process form egg-shell confine Zn2+, rendering 2D growth mode inhibiting dendrite growth.
