Determining the alumina solubility in low-temperature KF-NaF-AlF3 melts using electrochemical methods

Results in Chemistry
Alumina solubility in KF-NaF-AlF3 melt was estimated using square wave voltammetry and linear sweep voltammetry methods. A 45° inclined and horizontal electrode were used in square wave voltammetry and linear sweep voltammetry, respectively.

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|
