The ZnO-SiO₂ Composite Phase with Dual Regulation Function Enables Uniform Zn²⁺ Flux and Fast Zinc Deposition Kinetics Toward Zinc Metal Batteries.

ABSTRACT: As an important candidate for rechargeable energy storage devices, the large-scale development of aqueous zinc ion batteries has been hindered by hydrogen evolution and uncontrollable dendrites of metal anodes. A novel ZnO-SiO₂ composite interface phase (Zn@ZSCP) with a double protective effect based on in situ synthesis by hydrothermal method is used to improve these difficulties. The hydrophilic SiO₂ layer is beneficial to the dissolution of hydrated zinc ions and reduces the nucleation barrier during zinc deposition, while the stable ZnO layer helps to adjust the electric field distribution on the surface of the metal anode to further induce uniform zinc nucleation. The cycle life of the Zn@ZSCP||Zn@ZSCP symmetric battery based on this innovative interface phase mo
