Abstract The severe dendrite issue of the Zn anode greatly hinders practical application aqueous zinc‐ion batteries, which demands a prompt solution. This work proposes an electrostripping strategy using sodium citrate (SC) solution as electrolyte to fabricate 3D honeycomb‐like (3DH‐Zn) anode. Theoretical calculations and experimental results reveal that SC preferentially adsorbs on Zn(100) Zn(101) planes exhibits shielding effect, leading major dissolution atoms from Zn(002) plane, thus obtaining structure. Notably, convinced by morphology characterization finite element simulation results, 2+ tends deposit lateral sides hexagonal holes 3DH‐Zn anode, resulting in flat deposition dominated Zn(101)/Zn(100) planes, significantly inhibits formation. As result, symmetric cell achieves ultra‐long lifespan 2000 h at 5.0 mA cm −2 1.0 mAh .

Abstract Rechargeable aqueous zinc‐ion (Zn‐ion) batteries are widely regarded as important candidates for next‐generation energy storage systems low‐cost renewable storage. However, the development of Zn‐ion is currently facing significant challenges due to uncontrollable Zn dendrite growth and severe parasitic reactions on metal anodes. Herein, we report an effective strategy improve performance by leveraging self‐assembly bovine serum albumin (BSA) into a bilayer configuration BSA′s hydrophilic hydrophobic fragments form unique intelligent ion channels, which regulate migration ions facilitate their desolvation process, significantly diminishing anodes leading uniform deposition along (002) plane. Notably, Zn||Zn symmetric cell with BSA electrolyte additive demonstrated stable cycling up 2400 hours at high current density 10 mA cm −2 . This work demonstrates pivotal role self‐assembled protein structures in improving durability batteries.
