Dendrite growth and side reactions of zinc metal anode have severely limited the practical application of aqueous zinc ion batteries (AZIBs). Herein, we introduce an artificial buffer layer composed of functional MXene (Ti 3 CN) for zinc anodes. The synthesized Ti 3 CN exhibits superior conductivity and features duplex zincophilic sites (N and F). These characteristics facilitate the homogeneous deposition of Zn 2+ , accelerate the desolvation process of hydrated Zn 2+ , and reduce the nucleation overpotential. The Ti 3 CN-protected Zn anode demonstrates significantly enhanced reversibility compared to bare Zn anode during long-term cycling, achieving a cumulative plating capacity of 10,000 mAh cm -2 at 10 mA cm -2 . In Ti 3 CN-Zn||Cu asymmetric cell, it maintains nearly 100 % Coulombic efficiency over 2500 cycles at 2 mA cm -2 . Furthermore, the assembled Ti 3 CN-Zn//δ-K 0.51 V 2 O 5 (KVO) full cell exhibit a low capacity decay rate of 0.002 % per cycle at 5 A/g. Even at 0 °C, the Ti 3 CN-Zn symmetric cell maintains steady cycling for 2000 h.
