Abstract Aqueous zinc‐ion batteries have emerged as promising candidates for large‐scale energy storage, but their cycle stability is limited by irreversible zinc anodes due to dendrite growth and undesired side reactions. Here, an artificial composite protective layer consisting of a Zn metal–organic framework (MOF) infiltrated with hydrophobic ionic liquid 1‐ethyl‐3‐methylimidazoline bis(trifluoromethyl sulfonyl) imide constructed on anodes. The unique porous structure the MOF enables uniform electric field distribution, effectively inducing plating stripping. Meanwhile, small amount can isolate direct contact between anode aqueous electrolyte, thereby inhibiting reactions including hydrogen evolution reaction. In addition, cations in act shielding suppress tip effect. Consequently, metal greatly improved. assembled symmetric cell able stably over 2600 h at 0.2 mA cm −2 /0.2 mAh 800 1 /1 , which also exhibits lower more stable overpotentials.

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.
