Tailoring the Solvation of Aqueous Zinc Electrolytes by Balancing Kosmotropic and Chaotropic Ions.

Aqueous zinc (Zn) batteries (AZBs) have emerged as a highly promising concept for grid-scale electrochemical energy storage due to the prospects of high safety, low cost, and competitive energy density. However, the commonly employed electrolytes, at ca. 0.

Comparing Computational Predictions and Experimental Results for Aluminum Triflate in Tetrahydrofuran.

Exploring reliable electrolytes for aluminum ion batteries requires an in-depth understanding of the behavior of aluminum ions in ethereal-organic solvents. Electrolytes comprised of aluminum trifluoromethanesulfonate (Al-triflate) in tetrahydrofuran (THF) were investigated computationally and experimentally. Optimized geometries, redox potentials, and vibrational frequencies of species likely to be present in the electrolyte were calculated by density functional theory and then measured spectroscopically and electrochemically.
