Abstract The uneven texture evolution of Zn during electrodeposition would adversely impact upon the lifespan aqueous metal batteries. To address this issue, tremendous endeavors are made to induce Zn(002) orientational deposition employing graphene and its derivatives. Nevertheless, effect prototype film over behavior has garnered less attention. Here, it is attempted solve such a puzzle via utilizing transferred high‐quality with controllable layer numbers in scalable manner on foil. multilayer fails facilitate epitaxial deposition, whereas monolayer slight breakages steers unique pinhole mode. In‐depth electrochemical measurements theoretical simulations discover that not only acts as an armor inhibit side reactions but also serves buffer homogenize initial nucleation decrease migration barrier, accordingly enabling smooth closely stacked polycrystalline domains. As result, both assembled symmetric full cells manage deliver satisfactory performances. This study proposes concept “pinhole deposition” dictate broadens horizons graphene‐modified anodes.

Abstract Aqueous zinc‐ion batteries (ZIBs) are promising candidates for grid‐energy storage due to their safety and cost‐effectiveness. However, the detrimental hydrogen evolution reaction (HER) dendrite growth on Zn‐metal anodes severely limit applications.
