Abstract Aqueous zinc‐ion batteries (AZIBs) have garnered significant interest for their potential in large‐scale energy storage, attributed to high safety and low cost. Nonetheless, issues such as limited cycling lifespan coulombic efficiency (CE) associated with dendrite formation uncontrollable side reactions on the Zn metal anode pose challenges that restrict practical applications. Herein, a dielectric filler‐assisted artificial hybrid interphase is constructed surface address faced by aqueous electrolytes. TiO 2 nanoparticles special properties promote solvation process carboxymethyl cellulose (CMC) acts physical barrier suppressing adverse blocking dendrite. Consequently, symmetric cell using modified zinc achieves prolonged cycle life of over 2500 h at 1 mAh cm −2 . Furthermore, full vanadium‐based cathode delivers excellent electrochemical performance (over 600 cycles A g −1 ). This research offers an efficient scalable approach enhance anodes.

The cyclability and reversibility of aqueous zinc-ion batteries (AZIBs) are severely hampered by the safety concerns arising from Zn dendrite growth. Therefore, a stable anode with inhibited dendrites side reactions is crucial for AZIBs. Herein, we utilized methyl acetoacetate (MA) as an additive to prevent growth enable highly reversible anodes. Benefiting nucleophilic groups (carbonyl groups) in MA, MA molecules can preferentially adsorb on anode/electrolyte interface (AEI), forming molecular protective layer. Such layers not only regulate migration deposition zinc ions, but also inhibit induced decomposition free H2O at AEI. symmetric cell addition achieves long-term cycling stability 1,500 h 2 mA cm-2 capacity mAh cm-2. In addition, Zn//NVO full using MA-contained electrolyte demonstrates high specific (138.4 g-1) outstanding retention (92.8% after 600 cycles) 1 A g-1. This work provides principle use ester-based additives suppress durable metal

The mounting accumulation of spent alkaline batteries (SABs) elicits concerns over both environmental threats and the recycling industry's profitability, closely tied to chemical reactions in manganese-based waste treatment. Herein, we design an acid-modulated phase-reconstruction strategy for sustainable recovery manganese oxides from SABs, where moderate proton participation facilitates preformation MnOOH intermediates before initial transformation ramsdellite-MnO2 (RM-R, orthorhombic) final conversion pyrolusite-MnO2 (RM-β, tetragonal) nanomaterials. This rarely reported metastable RM-R phase features a unique tunneled framework (1 × 2 edge-shared MnO6 octahedra) enabling reversible H+/Zn2+ (de)intercalation, though its traditional synthesis remains challenging due thermodynamic instability. First-principles calculations reveal that possesses lower Zn2+ diffusion barriers (0.44 eV) than RM-β (0.99 eV), consistent with superior storage performance. Moreover, higher specific surface area enables cathode battery-supercapacitor hybrid behavior, which delivers remarkable capacity (214.9 mA h g-1 at 0.1 A g-1) long cycling stability (98% retention after 1000 cycles), outperforming most MnO2-based cathodes. low-acid regeneration protocol (4 mL HCl/1.85 g waste) paves way closed-loop battery clarifies structure-property relationships oxides.
