Building Sustainable Saturated Fatty Acid-Zinc Interfacial Layer toward Ultra-Stable Zinc Metal Anodes

Nano Letters, Год журнала: 2023, Номер 23(8), С. 3573 - 3581

Опубликована: Апрель 12, 2023

The commercialization pace of aqueous zinc batteries (AZBs) is seriously limited due to the uncontrolled dendrite growth and severe corrosion reaction anode. Herein, a universal extendable saturated fatty acid-zinc interfacial layer strategy for modulating redox process toward ultrastable Zn metal anodes proposed. in situ complexing interphases could construct an extremely thin compound with continuously constructed zincophilic sites which kinetically regulates nucleation deposition behaviors. Furthermore, multifunctional internal hydrophobic carbon chains as protective efficient exclude active water molecules from surface efficiently inhibit zinc. Consequently, modified anode shows long cycle life over 4000 h at 5 mA cm–2. In addition, assembled Zn||V2O5 full cells based on have excellent rate performance stability.

Insight on the Double‐Edged Sword Role of Water Molecules in the Anode of Aqueous Zinc‐Ion Batteries

Small Structures, Год журнала: 2022, Номер 3(12)

Опубликована: Сен. 23, 2022

As promising candidates for aqueous metal batteries, zinc‐ion batteries (ZIBs) have attracted more attention due to their superior safety, low cost, and environmentally benign characteristics. Solvent water plays a double‐edged sword role that cannot be ignored in the electrochemical performance long cycling stability of batteries. The hydrated zinc ions solvated structure can boost diffusion kinetics ions, whereas released active molecules during desolvation lead notorious hydrogen evolution reactions, dendrites growth, surface passivation at unstable interface between electrolyte anode. Unlike previous reports summarize recent research progress, this review focuses on anode processes ZIBs. influencing mechanism energy storage process is systematically discussed, including basic theory, regulation strategies, reports. two‐faced identity profoundly revealed herein, some revelatory insights possible strategies are provided future design stable durable anodes high‐performance

Опубликована: Май 18, 2023

MXenes are emerging 2D materials that have gained great attention because of their unique physical-chemical properties. However, the wide application is prohibited by high cost and environmentally harmful synthesis process. Here a fluoride- acid-free physical vacuum distillation strategy proposed to directly synthesize series MXenes. Specifically, introducing low-boiling-point element into MAX subsequently evaporating A elements via distillation, fluoride-free (Ti3C2Tx, Nb2CTx, Nb4C3Tx, Ta2CTx, Ti2NTx, Ti3CNTx, etc.) fabricated. This green one-step process without any acid/alkaline involved with all reactions inside tube furnace, avoiding contamination external environments. Besides, synthetic temperature controlled regulate layered structures specific surface areas Accordingly, synthesized Ti3C2Tx MXene exhibits improved sodium storage performance. method may provide an alternative for scalable production other materials.
