Aqueous zinc (Zn) ion batteries are attractive for next generation with high safety, yet their applications still hindered by the uncontrollable dendrite formation and side reactions on Zn anode. Here, a polyzwitterion protective layer (PZIL) was engineered polymerizing 2-methacryloyloxyethyl phosphorylcholine (MPC) in carboxymethyl chitosan (CMCS), which renders following merits: choline groups of MPC can preferentially adsorb onto metal to avoid reactions; charged phosphate chelate Zn2+ regulate solvation structure, further improving reaction inhibition; Hofmeister effect between ZnSO4 CMCS enhance interfacial contact during electrochemical characterization. Consequently, symmetrical battery PZIL keep stable more than 1000 hours under ultra-high current density 40 mA cm-2 . The confers Zn/MnO2 full Zn/active carbon (AC) capacitor cycling performance density.

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 .
