How Solvation Energetics Dampen the Hydrogen Evolution Reaction to Maximize Zinc Anode Stability
Zinc anode stability improves markedly when a TAS additive displaces water from the Zn2+ solvation shell, dampening solvation energetics to suppress both the hydrogen evolution reaction and dendrite formation by roughly an order of magnitude.
