Rechargeable aqueous aluminum ion batteries (AAIBs) offer a promising avenue for achieving safe, high-energy, and low-cost large-scale energy storage applications. However, the practical development of AAIBs is hindered by competitive reduction reactions in solution, which lead to insufficient (Al) deposition severe hydrogen evolution reaction (HRE). In this work, an inorganic/organic hybrid hydrogel with stable silicon-based network multiple polar sites successfully fabricated via situ sol-gel polymerization method. The preferential formation bonds between functional groups water molecules effectively reduces thermodynamic reactivity water. Furthermore, X-ray photoelectron spectroscopy (XPS) time flight secondary mass spectrometry (TOF-SIMS) analyses confirm stable, inorganic-rich solid electrolyte interface (SEI) layer, kinetically suppresses undesirable side reactions. This exhibits high ionic conductivity 2.9 × 10-3 S cm-1 at 25 °C, even under lean-water conditions.

Aqueous rechargeable manganese (Mn)-ion batteries have recently emerged as a promising candidate for multivalent ion batteries. However, challenges remain, particularly in expanding the electrolyte's voltage window and identifying compatible anode materials. Herein, we introduce Mn-ion full battery comprising nickel hexacyanoferrate (NiHCF) cathode, perylene-3,4,9,10-tetracarboxylic diimide (PTCDI) anode, novel hydrated eutectic electrolyte formulated from Mn(ClO4)2·6H2O acetamide. This composition, optimized molar ratio, provides stable solvation structure that suppresses water reactivity supports high ionic conductivity, confirmed by spectroscopic molecular dynamics analyses. The PTCDI facilitates highly reversible Mn2+ storage via unique enolization redox reaction, delivering exceptional rate capability cycling stability. As result, NiHCF||PTCDI achieves 1.2 V plateau, excellent performance (up to 5.0 A g-1), long life with 95.6% capacity retention over 1200 cycles at 1.0 g-1. study proposes feasible strategy construction of environment-friendly, long-life low-cost aqueous batteries, offering sustainable high-performance solution future energy applications.

Abstract Rechargeable aluminum batteries (RABs) have garnered attention owing to their impressive theoretical capacity, outstanding safety features, and abundant Al reserves, thereby positioning them as a potential alternative supplement fixed energy storage. Nonetheless, RABs still suffer from issues, such poor anode stability stemming the corrosivity of chloral aluminate ionic liquid electrolyte (ILs) subpar wettability cathode. To address these proposed interfacial engineering involves nonionic surfactant (F127) an optimizer in ILs, simultaneously modulating anode–electrolyte cathode–electrolyte interfaces. Systematic experiments analyses validate that F127 preferentially adsorbs on electrode surface, forming dense uniform adsorption layer. The layer can effectively mitigate corrosion ILs regulate current density achieve deposition. Furthermore, enhances between cathode preventing collapse graphite structure enhancing active material's utilization. Al//FG full battery assembled with modifying (F127‐0.5) is able retain specific capacity 104.9 mAh g −1 after 1600 cycles, which higher than (69.0 ). This interface modification strategy holds considerable practical significance for achieving long‐lifespan high‐capacity RABs.
