Mosaic Nanocrystalline Graphene Skin Empowers Pragmatic Zn Metal Anodes

, 2022
AbstractConstructing a conductive carbon-based artificial interphase layer (AIL) to inhibit dendritic formation and side reaction plays a pivotal role in achieving longevous Zn anodes. Distinct from the previously reported carbonaceous overlayers with sigular dopants and thick foreign coatings, a new type of N/O co-doped carbon skin with ultrathin ...

Tuning the Selectivity of the CO2 Reduction Reaction by Means of Synergistic Interactions in the Cu, Ag, Ce System

Advanced Functional Materials, EarlyView.
Multi‐metal Cu─Ce─Ag nanoparticles harness synergistic interactions to drive efficient electrochemical CO2 reduction reaction toward C2+ products at high current densities. Ag enhances CO production, Ce modulates Cu oxidation states, and together they boost *CO coverage and local pH to enhance C─C coupling, enabling record C2+ yields with suppressed ...

Releasing plating-induced stress for highly reversible aqueous Zn metal anodes

Nano Energy, 2022
Rechargeable aqueous zinc-ion batteries (ZIBs) have become one of the most potential technologies for grid-scale energy storage systems. The practical application, however, has been severely plagued by the uncontrollable dendrite growth and side reactions on ZIB anodes with planar structure, making it urgent to develop efficient strategies to stabilize

Interfacial and Crystallographic Regulation of Zinc Anode via Electric Double Layer Reconstruction for Highly Stable Zn Anode

Advanced Functional Materials, EarlyView.
Trace amounts of perfluoro‐1‐butanesulfonyl fluoride enables the regulation of the Zn/electrolyte interface by the generated zincophilic ─SO3H groups with long hydrophobic ─CF2 tails, which adsorb strongly onto the Zn surface, displace water molecules from the inner Helmholtz plane, and reconstruct the electrical double‐layer structure.

Interfacial Confinement Effect of Self‐Adsorbed Monolayer Enables Highly Reversible Zn Metal Anodes

Advanced Science
The practical applications of aqueous Zn metal batteries are promising, yet still impeded by the corrosion reactions and dendrite growth on the Zn metal anode. Here, a self‐adsorbed monolayer (SAM) is designed to stabilize the Zn metal anode.
