Abstract Aqueous Zn/V 2 O 5 batteries are featured for high safety, low cost, and environmental compatibility. However, complex electrode components in real impede the fundamental understanding of phase transition processes intercalation chemistry. Here, model based on V film electrodes which show similar electrochemical behaviors as ones built. Advanced surface science characterizations allow to identify trajectories Zn 2+ , H O, + during processes. Protons serve vanguard intercalated species, facilitating subsequent O. The increase capacity activation process is mainly due from more active ·nH structure caused by partial irreversible deintercalation rather than sites induced grain refinement materials. Eventually, accumulation species within oxide results formation inactive (Zn 3 (OH) 7 ·2H O) structure. established chemistry helps design high‐performance

Abstract The application of zinc‐ion batteries (ZIBs) is seriously challenged by the poor stability Zn anode and cathode in aqueous solution, which closely associated with electrolyte structure water reactivity. Herein, issues both for can be simultaneously addressed via tuning solvation hybrid tripropyl phosphate (TPP) as co‐solvent. On anode, a robust poly‐inorganic solid interphase (SEI) layer comprised 3 (PO 4 ) 2 ‐ZnS‐ZnF species situ formed, effectively suppressing parasitic reaction dendrite evolution. For V O 5 cathode, notorious vanadium dissolution restricted improved achieved. optimized facilitates reversible redox kinetics at anode. Consequently, Zn||Zn cells display extended cycling lifespans over 3000 h 1 mA cm −2 , mAh .

Abstract Zinc‐ion batteries (ZIBs) have promising prospects in energy storage field, but the water molecules aqueous electrolytes significantly compromise stability of anode and cathode interfaces hinder low‐temperature performance. Herein, water‐in‐oil type Möbius polarity topological solvation composed oil, water, amphiphilic salt are first‐ever pioneered, forming surfactant‐free microemulsion electrolyte (SFMEE). This structure, characterized by its distinct inner outer layers a inversion feature, successfully connects non‐polar phase with polar phase, eliminating need for surfactants to reduce costs system complexity. The anion creates singularity stabilizes polarity‐reversed encapsulation. oil layer disrupts cohesive network constructs cage restrict water. A series SFMEE combinations investigated then directly applied ZIBs, confirming excellent universality durability this design.

Abstract Aqueous zinc‐ion batteries (AZIBs) are a promising alternative to lithium‐ion batteries, boasting superior safety, eco‐friendliness, and cost‐effectiveness. Despite these advantages, performance issues such as irregular Zn deposition cathode material dissolution remain challenging. This study introduces an intrinsically anisotropic ion‐guiding hydrogel electrolyte (APHE) fabricated via double‐stabilization freezing strategy. The synergistic effect of structure high water affinity APHE effectively suppress water‐induced parasitic reactions. In brief, the promotes rapid 2+ ion diffusion, leading uniform flux. Additionally, abundant hydroxyl groups in facilitate dissociation adjust solvation structure, setting it apart from isotropic matrix. Furthermore, improvement diffusion tortuosity enhances electrode/electrolyte kinetics, thereby improving rate‐capability reversibility (de)‐intercalation. Thus, demonstrates thin dense layer 31.7 µm, which is less than half thickness IPHE (67.5 µm) after 500 cycles. research addresses fundamental challenges AZIBs provides valuable insights into design advanced electrolytes for future energy storage systems.
