Mn2+ Ion‐Mediated Zn Dendrite Suppression and Reversible Stripping in Aqueous Zn‐Ion Batteries as Revealed by In Situ Liquid‐Cell TEM

Advanced Science, EarlyView.
In situ EC‐LPTEM directly visualizes how Mn2+ ions regulate Zn electrodeposition and dissolution in aqueous electrolytes. Mn2+ suppresses heterogeneous growth and dendritic elongation while promoting more reversible stripping. These findings reveal additive‐regulated interfacial processes during Zn deposition and dissolution and provide guidance for ...

Chelation-Driven Dual-Interface Regulation for Long-Life Aqueous Zn-I₂ Batteries. [PDF]

Adv Sci (Weinh)
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

Overcoming the Catalytic Bucket Effect in Pt‐based High‐Entropy Nanocages Through Interface Defect and Strain Engineering

Advanced Science, EarlyView.
PtPdNiCuMnAu HENCs exhibit a remarkable half‐wave potential (E1/2) of 0.925 V vs. RHE. The catalyst displays exceptional electrochemical stability, with only a 4 mV negative shift in E1/2 and a mere 5.6% loss in MA after 10, 000 accelerated durability test cycles.

Continuous‐Flow Microfluidic Synthesis Enhances C2+ Selectivity for Cu2O Catalysts

Advanced Science, EarlyView.
Microfluidic devices are used to prepare Cu2O nanoparticles under laminar flow conditions, which exhibit enhanced selectivity in the CO2‐to‐C2+ reaction due to their nanoporosity and high defect concentration. Cu2O prepared using standard solution methods displays decreased CO2‐to‐C2+ selectivity due to the absence of similar properties. Altogether, we

A Bifunctional Organosilane Additive for Dynamic pH Regulation and Interfacial Protection in Aqueous Zinc‐Ion Batteries

Advanced Science, EarlyView.
A novel multifunctional additive for aqueous zinc‐ion battery electrolytes can simultaneously dynamically adjust the pH in microzones, regulate the solvation structure of Zn2+, protect the interface, and form a stable solid‐state SEI film. This approach enables a dendrite‐free zinc anode and demonstrates excellent cycling stability and cycle life ...

Balancing Bulk Solution Chemistry and Cation Solvation for Stable Aqueous Aluminum Batteries

Advanced Science, EarlyView.
A dual‐scale electrolyte design balances bulk solution chemistry and cation solvation in aqueous aluminum batteries. Regulation of the bulk solution preserves high ionic conductivity and electrochemical stability, while modulation of the Al3+ solvation environment lowers desolvation penalties and suppresses hydrogen evolution. This balanced electrolyte

Adaptive Cu Reconstruction in Heterostructure Drives High‐Rate Nitrate‐to‐Ammonia Conversion

Advanced Science, EarlyView.
An adaptively reconstructed Cu/CoOX heterojunction, featuring a surface‐localized, hydroxyl‐rich oxidized Cu species, forms in situ from a CuO/CoOX (Co1Cu9OX) pre‐catalyst during electrochemical nitrate reduction. The self‐adaptive reconstruction and the incorporation of heterostructure regulate nitrogen‐containing intermediate adsorption and *H supply,
