Abstract Zn metal is a promising anode material in aqueous batteries, but the direct use of foil encounters severe issues dendrite formation and side reactions, causing short cycle life. Conventional thick rigid insulating protection layers may impede ion diffusion detach during mechanical deformation battery. Herein, dendrite‐free zinc demonstrated by grafting thin (≈10 nm) Ti 3 C 2 T x MXene functional membrane which formed via Marangoni‐driven self‐assembly. The initiates uniform nucleation promotes deposition (002)‐oriented lateral growth mode. Meanwhile, functions as soft, stress‐adaptive, protective layer to underneath active zinc. This renders with improved cycling stability without notable or side‐reaction products. Flexible Zn─I pouch cells fabricated from MXene‐covered (20 µm thick) modified ZnI cathode demonstrate stable capacity up 1500 cycles unchanged voltage upon various deformations. work affords new insights into designing soft membranes for constructing flexible Zn‐based energy devices.
