The practical deployment of rechargeable aqueous zinc-ion batteries is greatly hindered by severe Zn dendrite growth and the hydrogen evolution reaction on Zn metal anodes. Herein, we report the spontaneous construction of an adsorption-induced o -carborane artificial interphase to stabilize Zn anodes. The cage-structured o -carborane clusters possess robust structural stability and chemical inertness, endowing Zn anodes with strong durability to suppress Zn dendrite and hydrogen evolution. The constructed o -carborane protective layer can redistribute Zn 2+ flux, avoiding nonuniform Zn deposition and achieving highly reversible Zn plating/stripping processes. The o -carborane-derived SEI can prevent Zn metal from being corroded by the electrolyte and accelerate Zn 2+ transfer. Consequently, Zn||Zn symmetric batteries and Zn||Cu half-batteries based on o -carborane-modified Zn electrodes demonstrate long cycling lifespans at elevated current densities. The assembled Zn||V 2 O 5 batteries also achieve lower voltage polarization, enhanced rate capability, and prolonged cycling stability. This work highlights the potential of adsorption-driven artificial interphases constructed from cage-like clusters in stabilizing transition metal anodes, providing a promising route to develop advanced aqueous multivalent-ion batteries.
