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 2M Zn(CF3SO3)2-0.2M acrylamide-0.2M 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 SO42- with Zn2+ and OH-...
