Abstract Zn anode is a promising candidate for aqueous batteries, but suffers from the dendrite growth and side reaction issues, leading to short cycling life unsatisfactory reversibility. Herein, Cu‐modified Ti 3 C 2 Cl MXene (Cu‐MXene) with high zincophilic hydrophobic property prepared one‐step molten salt etching method. Serving as protective coating on anode, Cu‐MXene can provide massive nucleation sites uniformize charge distribution, homogenous deposition. Moreover, prevent electrolyte, beneficial suppressing reactions such hydrogen evolution corrosion. Therefore, stable reversible plating/stripping achieved coated by Cu‐MXene, which delivers an extended of over 1000 h low polarization within 120 mV at 10 mA cm −2 , coulombic efficiency 99.6% 1100 cycles, indicating excellent stability reversibility stripping/plating. The practical full cell coupled NaV O 8 ·1.5H cathode also displays performance cycles. proposed reveals prospect designing highly be other energy storage systems based metal anodes.

Engineering Covalent Organic Frameworks Toward Advanced Zinc‐Based Batteries

Advanced Materials, Год журнала: 2024, Номер 36(24)

Опубликована: Март 16, 2024

Zinc-based batteries (ZBBs) have demonstrated considerable potential among secondary batteries, attributing to their advantages including good safety, environmental friendliness, and high energy density. However, ZBBs still suffer from issues such as the formation of zinc dendrites, occurrence side reactions, retardation reaction kinetics, shuttle effects, posing a great challenge for practical applications. As promising porous materials, covalent organic frameworks (COFs) derivatives rigid skeletons, ordered structures, permanent porosity, which endow them with application in ZBBs. This review, therefore, provides systematic overview detailing on COFs structure pertaining electrochemical performance ZBBs, following an depth discussion challenges faced by includes dendrites reactions at anode, well dissolution, structural change, slow effect cathode. Then, COF-correlated materials roles various are highlighted. Finally, outlined outlook future development is provided. The review would serve valuable reference further research into utilization

Regulating the Inner Helmholtz Plane with a High Donor Additive for Efficient Anode Reversibility in Aqueous Zn‐Ion Batteries

Angewandte Chemie, Год журнала: 2023, Номер 135(21)

Опубликована: Март 24, 2023

Abstract The performance of aqueous Zn ion batteries (AZIBs) is highly dependent on inner Helmholtz plane (IHP) chemistry. Notorious parasitic reactions containing hydrogen evolution (HER) and dendrites both originate from abundant free H 2 O random deposition inside active IHP. Here, we report a universal high donor number (DN) additive pyridine (Py) with only 1 vol. % addition (Py‐to‐H volume ratio), for regulating molecule distribution Density functional theory (DFT) calculations molecular dynamics (MD) simulation verify that incorporated Py could tailor 2+ solvation sheath exclude molecules IHP effectively, which in favor preventing decomposition. Consequently, even at extreme conditions such as depth discharge (DOD) 80 %, the symmetric cell based can sustain approximately 500 h long‐term stability. This efficient strategy DN additives furnishes promising direction designing novel electrolytes promoting practical application AZIBs, despite inevitably introducing trace organic additives.
