Compared with prevailing Zn foil, Zn powders (ZnP) with special‐shaped tunability and large‐scale processability are considered promising anodes for propelling Zn batteries, but face the issue of discrete contact between Zn particles due to their intrinsic monodispersed geometries. Here a novel biomimetic quasi‐skin‐capillary ZnP anode with ionic‐electronic conducting full‐chain networks (ZnP‐FC) is designed, characterized by an aramid nanofiber (ANF) surface coating (skin) and a ZnP‐ANF interwoven inner skeleton (capillary). The epidermal coating not only stabilizes the anode/electrolyte interface to homogenize Zn2+ flux and shields direct contact between H2O and ZnP but also extends inward as a capillary‐like adhesive to anchor ZnP and affords high Zn2+ selectivity for boosting plating/stripping efficiency. Benefiting from these favorable attributes, ZnP‐FC||ZnP‐FC cell enables high kinetics and stable ion migration to afford a long‐term operation for over 1650 h at 5 mA cm−2. Moreover, ZnP‐FC||KV12O30‐y·nH2O full battery harvests a high‐rate capability (15 A g−1) and ultralong cyclic stability (6000 cycles). This work extends the structural engineering landscape of Zn powder anodes for advanced batteries.
