Non-flammable, dilute, and hydrous organic electrolytes for reversible Zn batteries.

ABSTRACT: Rechargeable Zn batteries hold great practicability for cost-effective sustainable energy storage but suffer from irreversibility of the Zn anode in aqueous electrolytes due to parasitic H₂ evolution, corrosion, and dendrite growth. Herein, we report a non-flammable, dilute, and hydrous organic electrolyte by dissolving low-cost hydrated Zn(ClO₄)₂·6H₂O in trimethyl phosphate (TMP), which homogenizes plating/stripping and enables in situ formation of a Zn₃(PO₄)₂-ZnCl₂-rich interphase to stabilize the Zn anode. A dilute 0.5 m Zn(ClO₄)₂·6H₂O/TMP electrolyte featuring a H₂O-poor Zn²⁺-solvation sheath and low water activity enables significantly e
