Abstract: The formation of solid-electrolyte interphase (SEI) in "water-in-salt" electrolyte (WiSE) expands the electrochemical stability window of aqueous electrolytes beyond 3.0 V. However, the parasitic hydrogen evolution reaction that drives anode corrosion, cracking, and the subsequent reformation… read more here.
