The inhomogeneous consumption of anions and direct contact between electrolyte and anode during the Zn‐deposition process generate Zn‐dendrites and side reactions that can aggravate the space‐charge effect to hinder the practical implementation of zinc‐metal batteries (ZMBs). Herein, electrospray has been applied for the scalable fabrication (>10 000 cm2 in a batch‐experiment) of hetero‐metallic cluster covalent‐organic‐frameworks (MCOF‐Ti6Cu3) nanosheet‐coating (MNC) with integrated micro space electrostatic field for ZMBs anode protection. The MNC@Zn symmetric cell presents ultralow overpotential (≈72.8 mV) over 10 000 cycles at 1 mAh cm−2 with 20 mA cm−2, which is superior to bare Zn and state‐of‐the‐art porous crystalline materials. Theoretical calculations reveal that MNC with integrated micro space electrostatic field can facilitate the deposition‐kinetic and homogenize the electric field of anode to significantly promote the lifespan of ZMBs.
