Abstract Anode‐free sodium metal batteries represent great promising as high‐energy‐density and resource‐rich electrochemical energy storage systems. However, the savage growth of continuous consumption hinder its stable capacity output. Herein, ordered flower‐edges zinc on Al substrate can induce high‐entropy solid electrolyte interphase (SEI) to adjust uniform deposition extremely reduce with ultrahigh initial Coulombic efficiency (97.05%) for prolong cycling life. Theoretical experimental studies have demonstrated that electron‐donating property exposed edge sites between (100) (101) facets in flower enhance anion adsorption onto inner Helmholtz plane accelerating interface decomposition. Additionally, edges serve homogeneous‐nucleating template, leading thin inorganic‐rich SEI layer (18 nm, ZnF 2 , NaZn 13 NaF, Na CO 3 ) discrete multicomponent distribution, so fast high‐flux ions transport field, thereby reducing critical nucleation barrier promoting high density (7.36 × 10 N cm −2 pyknotic (3 mAh 22 µm). The assembled anode‐free exhibit stability (86%, 90 cycles) under cathode loading (32 mg ). Moreover, anode‐less single‐layer pouch a durable retention 99% after 600 cycles.

Abstract The formation of inactive sodium on the substrate is considered to be a critical cause capacity decay in anode‐free batteries (AFSBs), but its mechanism has been insufficiently understood. Herein, for first time, it revealed that inability provide an efficient electron transport pathway stripping due crystal mismatch and weak lattice forces between intrinsic AFSBs. Therefore, indium coating strategy offers favorable matching force with proposed. Sodium can uniformly grow indium‐modified substrates low nucleation barriers, without shedding, this modulating effect sustained over extended cycling periods. Ultimately, pouch‐type AFSBs assembled Na 4 Fe 2.91 (PO ) 2 (P O 7 (NFPP) cathode (≈18 mg cm −2 mass loading) copper foil exhibit retention 78.3% after 320 cycles at 2C rate, whereas bare only less than 60 times. Most importantly, proposed work offer lattice‐ atomic‐scale insights design advanced
