Rational Design of an In-Situ Polymer-Inorganic Hybrid Solid Electrolyte Interphase for Realising Stable Zn Metal Anode under Harsh Conditions.

ABSTRACT: The in-depth understanding of the composition-property-performance relationship of solid electrolyte interphase (SEI) is the basis of developing a reliable SEI to stablize the Zn anode-electrolyte interface, but it remains unclear in rechargeable aqueous zinc ion batteries. Herein, a well-designed electrolyte based on 2 M Zn(CF₃SO₃)₂-0.2 M acrylamide-0.2 M ZnSO₄ is proposed. A robust polymer (polyacrylamide)-inorganic (Zn₄SO₄(OH)₆.xH₂O) hybrid SEI is in situ constructed on Zn anodes through controllable polymerization of acrylamide and coprecipitation of SO₄ ^2- with Zn²⁺ and OH^-. For the first time, the underlying SEI composition-property-performance relations
