Aqueous zinc batteries (AZBs) feature high safety and low cost, but intricate anodic side reactions dendrite growth severely restrict their commercialization. Herein, ethylenediaminetetraacetic acid (EDTA) grafted metal organic framework (MOF-E) is proposed as a dually-functional interphase for sustainable Zn anode. Specifically, the target-distributed EDTA serves an ion-trapped tentacle to accelerate desolvation ionic transport by powerful chemical coordination, while MOFs offer suitable channels induce oriented deposition. As result, MOF-E fundamentally suppresses guides horizontally arranged deposition with (002) preferred orientations. The Zn|MOF-E@Cu cell exhibits markedly improved Coulombic efficiency of 99.7 % over 2500 cycles, MOF-E@Zn|KVOH (KV12 O30-y ⋅ nH2 O) yields steady circulation 5000 [email protected] at 8 A g-1 .

Aqueous zinc metal batteries (AZMBs) are promising candidates for next-generation energy storage due to the excellent safety, environmental friendliness, natural abundance, high theoretical specific capacity, and low redox potential of (Zn) metal. However, several issues such as dendrite formation, hydrogen evolution, corrosion, passivation Zn anodes cause irreversible loss active materials. To solve these issues, researchers often use large amounts excess ensure a continuous supply materials anodes. This leads ultralow utilization squanders density AZMBs. Herein, design strategies AZMBs with discussed in depth, from utilizing thinner foils constructing anode-free structures 100%, which provides comprehensive guidelines further research. Representative methods calculating depth discharge different first summarized. The reasonable modification foil anodes, current collectors pre-deposited Zn, aqueous (AF-AZMBs) improve then detailed. In particular, working mechanism AF-AZMBs is systematically introduced. Finally, challenges perspectives high-utilization presented.

Abstract The undesirable side reactions and uncontrolled deposition leads to the electrochemical failure of Zn metal anodes. Herein, driven by theory calculations, a surface texture engineering passivation layer protection dual‐interface strategy is developed. Benefiting from complementary interface effect, such can realize integrated regulation interfacial transport deposition. That is, inhibiting water‐induced reactions, accelerating de‐solvation hydrated zinc ions, homogenizing ion flux, guiding Zn(002)‐preferred orientation As result, modulated electrode enables significantly extended stability smaller nucleation barrier polarization effect. Unexpectedly, it steadily operate for 6600 h at 0.5 mA cm −2 , corresponding lifespan >9 months. Highly reversible plating stripping be still retained when current density improved up 1, 5, 10, even 20 . Beyond that, applied batteries, enhanced rate capability, cyclic realized in both aqueous Zn/MnO 2 batteries solid‐state Zn/VO batteries. This design concept effect expected provide new insight into high reversibility
