Multifunctional interfacial engineering on the Zn anode to conquer dendrite growth, hydrogen evolution, and sluggish kinetics associated with deposition is highly desirable for boosting commercialization of aqueous zinc-ion batteries. Herein, a spontaneous construction carbonyl-containing layer (Zn@ZCO) rationally designed as an ion redistributor functional protective interphase. It has strong zincphilicity suppression ability due significant interaction electronegative nucleophilic carbonyl oxygen, favoring transport homogenizing effectively. On other side, bond formed by proton acceptor oxygen atom in ZCO regulates Zn-ion desolvation process at interfaces, thus bounding water activity then mitigating water-induced parasitic reactions. Consequently, Zn@ZCO exhibits extended cycling lifespan 5000 h (>208 days) dendrite-free surface negligible by-products. More encouragingly, effectiveness also convincing NH4 V4 O10 -based full-cells excellent rate performance cyclic stability. The stabilized enabled strategy solid electrolyte interphase brings forward facile instructive approach toward high-performance zinc-storage systems.

Abstract Zinc ion batteries (ZIBs) have been gradually developed in recent years due to their abundant resources, low cost, and environmental friendliness. Therefore, ZIBs received a great deal of attention from researchers, which are considered as the next generation portable energy storage systems. However, poor overall performance restricts development, is attributed zinc dendrites series side reactions. Constructing 3D anodes has proven be an effective way significantly improve electrochemical performance. In this review, challenges ZIBs, including dendrites, hydrogen evolution corrosion, well passivation, comprehensively summarized mechanisms discussed. with different structures fiberous, porous, ridge‐like structures, plated on substrates other anodes, subsequently discussed detail. Finally, emerging opportunities perspectives material design highlighted that need solved future practical applications discussed, hopefully illuminating forward for development ZIBs.

Abstract Designing a multifunctional separator with abundant ion migration paths is crucial for tuning the transport in rocking‐chair‐type batteries. Herein, polydopamine‐functionalized PVDF (PVDF@PDA) nanofibrous membrane designed to serve as aqueous zinc‐ion batteries (AZIBs). The functional groups (OH and NH) PDA facilitate formation of ZnO ZnN coordination bonds Zn ions, homogenizing Zn‐ion flux thus enabling dendrite‐free deposition. Moreover, PVDF@PDA effectively inhibits shuttling V‐species through VO bonds. As result, Zn/NH 4 V O 10 battery exhibits enhanced cycling stability (92.3% after 1000 cycles at 5 A g −1 ) rate capability compared that using glass fiber separator. This work provides new avenue design functionalized separators high‐performance AZIBs. image

Abstract Building an artificial interphase layer for tackling uncontrollable Zn dendrites and serious side reactions is a highly desirable strategy, but it often hampered by the limited 2+ transport. Here, stable fluorine‐doped amorphous carbon (CF) constructed on Cu current collector (CF‐Cu) via facile carbonization treatment of fluoropolymer coating to realize underlying deposition. As evidenced experimentally theoretically, this inorganic CF with ionic conductivity electronic insulation successfully triggers dendrite‐free deposition at CF‐Cu interface preferred Zn(002) crystal plane stacking parallel substrate surface, thus greatly promoting inhibition Zn‐dendrites blocking interfacial reactions. The introduced fluorine atoms as abundant zincophilic sites play important role in driving fast zinc‐ion transfer kinetics, which can partly convert into ZnF 2 solid conductor further guide uniform Consequently, electrode enables high reversibility 99% coulombic efficiency long cycling stability 1900 cycles mA cm –2 . integrated CF‐Cu@Zn anode achieves up 2200 h low voltage polarization.

Rechargeable aqueous Zn-VOx batteries are attracting attention in large scale energy storage applications. Yet, the sluggish Zn2+ diffusion kinetics and ambiguous structure-property relationship always challenging to fulfil great potential of batteries. Here we electrodeposit vanadium oxide nanobelts (VO-E) with highly disordered structure. The electrode achieves high capacities (e.g., ≈5 mAh cm-2 , 516 g-1 ), good rate cycling performances. Detailed structure analysis indicates VO-E is composed integrated amorphous-crystalline nanoscale domains, forming an efficient heterointerface network bulk electrode, which accounts for electrochemical properties. Theoretical calculations indicate that heterostructure exhibits favorable cation adsorption lower ion barriers compared amorphous crystalline counterparts, thus accelerating charge carrier mobility activity electrode.
