The aqueous iron ion batteries (AIIBs) are an attractive option for large-scale energy storage applications. However, the inadequate plating and stripping of Fe2+ ions underscore need to explore more suitable cathode materials. Herein, we optimize structure tunnel-like VO2 nanosheets by introducing Mn2+ intercalation as a material enhance their performance in AIIBs. serves stabilizing pillar VO2, which brings some oxygen vacancies provide extra electrochemically active sites, accelerates reversible (de)insertion ions. In addition, density functional theory (DFT) calculations show that introduction reduces band gap also decreases electrostatic interaction between VO2. Consequently, with interlayer pillars (5% MVO) electrodes exhibit remarkable capacity 284.32 mAh g-1 at current 0.1 A demonstrate excellent cycle life, maintaining 81.7% 1.0 after 600 cycles. Therefore, these results offer promising choice achieve outstanding electrochemical

Abstract Aqueous zinc‐ion batteries (AZIBs) have garnered significant attention as promising next‐generation energy storage devices due to their advantages of low cost, operational safety, and high theoretical specific capacity. Nevertheless, interface instability issues including dendrite growth, hydrogen evolution, corrosion severely compromise zinc anode reversiblity. This study presents a novel strategy employing CuZn alloy nanoparticles anchored on graphene sheets (CZPG) multifuctional protective coating. The CZPG architecture establishes dual‐functional interface: provides high‐conductivity pathways abundant nucleation sites, while demonstrate expecetional zincophilicity evolution suppression. alloy's elevated dezincification potential synergizes with graphene's conductive network regulate Zn 2+ flux distribution deposition kinetics. Systematic characterization reveals that the coating enable homogeneous suppressing parasitic reactions. Consequently, CZPG@Zn symmetric cells achieve remarkable cycling stability exceeding 1300 h at 5.0 mA·cm −2 2.5 mAh·cm , providing 24‐fold increase in cycle life compared bare Zn. When paired KVO cathodes, full maintain 81.9% capacity retention after 1000 cycles, demonstrating 10‐fold improvement over conventional anodes. interfacial engineering approach through alloy‐graphene hybrid coatings new insights for developing high‐preformance AZIBs, showing grid‐scale enegy applications.

Enhancement of De‐Solvation Kinetics on V₅O₁₂•6H₂O Cathode Through a Bi‐Functional Modification Layer for Low‐Temperature Zinc‐Ion Batteries

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 10, 2024

Abstract Zinc‐ion batteries (ZIBs) show great promise for next‐generation energy storage, but their performance at low temperatures is severely hindered by sluggish desolvation kinetics cathode‐electrolyte interface. To address this limitation, a zincophilic‐hydrophobic poly(3,4‐ethylenedioxythiophene) (PEDOT) modified layer proposed on V 5 O 12 •6H 2 cathode. Ab initio molecular dynamics simulations indicate that modification strategy promotes Zn ⁺ adsorption and reduces the free dissociating hydrated 2+ to form interface, across temperature of 280 240 K. As result, PEDOT‐modified cathode exhibits significantly improved diffusion kinetics, delivering superior rate with remarkable capacity 226.5 mAh g⁻¹ 40 A g⁻¹. Notably, even −30 °C, maintains high 268.3 mA 0.2 robust retention (92.4%) over 1,000 cycles 1 This approach markedly improves low‐temperature operational efficiency, highlighting potential interface engineering advance zinc‐ion in cold environments.
