Circumneutral concentrated ammonium acetate solution as water-in-salt electrolyte

نویسندگان

چکیده

The exponentially growing market of electrochemical energy storage devices requires substitution flammable, volatile, and toxic electrolytes. use Water in salt solutions (WiSE) regarded as green electrolyte might be interest thanks to an association key features such high safety, low cost, wide stability, ionic conductivity. Here, we report comprehensive chemical-physical study circumneutral WiSE based on ammonium acetate so investigate application systems, with focus the effect pH, density, viscosity, conductivity, ESW concentration ranging from 1 30 mol/kg . Data are reported discussed respect structure investigated by complemental IR molecular dynamic study. is addressed through showcase asymmetric supercapacitor Argan shell-derived carbon electrodes tested at temperatures -10 80 {\deg}C.

Water dynamics in divalent and monovalent concentrated salt solutions.

Water hydrogen bond dynamics in concentrated salt solutions are studied using polarization-selective IR pump-probe spectroscopy and 2D IR vibrational echo spectroscopy performed on the OD hydroxyl stretching mode of dilute HOD in H(2)O/salt solutions. The OD stretch is studied to eliminate vibrational excitation transfer, which interferes with the dynamical measurements. Though previous researc...
