Passivated Zn Powders as Metal Anode

Advanced Materials Interfaces
AbstractImpacted by heavy corrosion and poor connections, zinc (Zn) powders have rarely been considered as the raw materials of Zn‐ion aqueous batteries (ZABs). Nonetheless, the ease of controlling loadings of Zn powders entitles ZABs to better capacity match between negative and positive electrodes.

pH‐Triggered Molecular Switch Toward Texture‐Regulated Zn Anode

Angewandte Chemie, 2023
AbstractZn electrodes in aqueous media exhibit an unstable Zn/electrolyte interface due to severe parasitic reactions and dendrite formation. Here, a dynamic Zn interface modulation based on the molecular switch strategy is reported by hiring γ‐butyrolactone (GBL) in ZnCl2/H2O electrolyte.

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.
