Abstract Anode‐free aqueous zinc (Zn) metal batteries (AFZMBs) possess an optimal battery architecture configuration because no excess Zn source is involved in the charge/discharge processes, rendering it feasible to enhance energy density of batteries. However, rapid capacity fading due unstable anode‐side current collector/electrolyte interfacial chemistry, which results dendrite growth, impedes their practical application, especially quasi‐solid‐state AFZMBs. Herein, a robust bilayer interphase design strategy between gel electrolyte and copper collector proposed achieve high‐energy stable Utilizing upper mass transfer layer regulate ion transport lower zincophilic electron induce initial uniform nucleation balance surface electric field, dendrite‐free deposition prominent reversibility are achieved. Therefore, significantly improves cycling stability Zn//I 2 Additionally, fabricated AFZMBs employing pre‐intercalated VO cathode deliver attractive power densities (186.1 Wh kg −1 /470 W 145.3 /1.74 kW , based on active material). Moreover, successful extension flexible offers promising pathway for development wearable electronic devices.

Abstract Developing a highly stable and dendrite‐free zinc (Zn) anode is crucial for the commercial application of aqueous Zn‐ion batteries. Herein, dual‐functional layer interface constructed on Zn surface via femtosecond laser processing strategy, effect periodic micro–nano structures accelerating transport dynamics ions suppressing dendrite growth investigated. The oxide exhibits strong affinity low diffusion barrier ions, significantly inhibiting corrosion side reactions. Meanwhile, subsurface dislocation can suppress deposited stress provide uniform distribution to improve strain resistance electrode. These integrated merits enable anodes with high reversibility 99.11% 1000 cycles, impressive cyclability 2678 h at 2 mA cm −2 /1 mAh . assembled full cell maximum 1300 cycles an enhanced capacity retention rate. Notably, large‐area pouch maintains cycling 100 excellent flexibility in flexible battery systems. This work highlights role laser‐induced optimizing deposition stimulates precise control characteristics achieving reversible anodes.
