Chemical and electrochemical synergistic weaving stable interface enabling longevous zinc plating/stripping process.

[Display omitted] • ZnSO 4 electrolyte is functionalized with AgNO 3 to uniformize the Zn+ deposition. • Chemical and electrochemical synergistic weaved Ag layer feature zincophilic sites. • Ag+ additive can effectively induce zinc dendrites growth and inhibit HER for AZIBs. • AZIBs with AgNO 3 additive deliver longevous cycle life over 1350 h. Dendrites growth and hydrogen evolution reaction of Zn anode greatly hinder the practical application of aqueous zinc ion batteries. Interface engineering strategies have attracted immense interest in addressing these challenges. Herein, a chemical and electrochemical method is proposed to synergistically weave a stable interface by introducing AgNO 3 additive in conventional aqueous ZnSO 4 electrolyte. The formed compact Ag layer acts as zincophilic sites, which is beneficial for zinc ion nucleation and growth. Consequently, the cell cycled in 2 M ZnSO 4 with 3 mM AgNO 3 electrolyte exhibits much more stable electrochemical properties than its counterpart. To be specific, the Zn || Zn half cell using the electrolyte with 3 mM AgNO 3 shows reversible Zn plating/stripping behavior over 1350 h at 5.0 mA cm−2 with an ultra-low potential hysteresis. Moreover, Zn || V 2 O 5 full cell using the electrolyte with 3 mM AgNO 3 exhibits glorious rate capability and more stable cycling performance, attributing to the inhibited zinc dendrites growth by the weaved interfacial layer. This work sheds new light on improving the electrochemical performance of rechargeable batteries. [ABSTRACT FROM AUTHOR]
