Consequently, the Zn|Zn cells with DE harvests an ultralong life of 6000 h at 0.5 mA cm-2 and 0.5 mAh cm-2 and 830 h even at a high depth of discharge of 80%. The results reveal that the DE not only enables an in-situ formed zincophilic layer to promote the uniform Zn deposition, but also alters the Zn2+ solvation chemistry to suppress water-induced side reactions. Here, we design a bio-inspired electrolyte (DE) with tetraethyl orthosilicate additive as a “healing agent” to dynamically repair the Zn surface wound. However, the water attack that consistently corrode the Zn anode surface with the notorious dendrite growth, hydrogen evolution and inactive by-product formation seriously impedes the practical applications of ZIBs. Rechargeable aqueous Zn-ion batteries (ZIBs) have drawn incredible attentions recently due to their high energy density, low cost and intrinsic safety.
