In Situ Formation of an In–Zn Interface Layer Enables Aqueous Zinc‐Ions Batteries with High Capacity Retention

open access: yesAdvanced Science, EarlyView.
This work demonstrates an indium zinc oxide (IZO)‐modified separator applied to aqueous zinc ion batteries (AZIBs), which in situ generates an In–Zn interface layer to stabilize the separator/anode region during the cycling process. The In–Zn interface layer provides richer nucleation sites for Zn2+ and suppresses side reactions.

Unsaturated Coordination Oxygen in Zn─V─O Vacancy Clusters Enables Superb Zinc Storage Capability

open access: yesAdvanced Science, EarlyView.
Zn3(VO4)2 with Zn─V─O vacancy clusters was synthesized and innovatively applied as cathode material in aqueous Zn‐ion batteries. In‐situ XRD, HRTEM and ab initio molecular dynamics simulations unveil the double reaction mechanism of zinc ions. Adsorption of zinc ions on unsaturated coordination O and H+ on O in ‐VO4 contributes to the main capacity. It

Redox‐Active Tungsten Mono‐Oxo Bis(dithiolene) Complex: A Fast‐Rechargeable Anode for High‐Capacity Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This study reports the first application of a W‐oxo bis(dithiolene) complex, (Et4N)2[WO(S2C2(C6H5)2)2], as a novel anode material for lithium‐ion batteries. This complex stores Li+ ions via multivalent W‐centered redox processes involving its oxo (WO) and dithiolene (S) sites.

Synergistic Organic–Inorganic Interface Engineering for Stable Zinc Metal Anodes in Aqueous Batteries

open access: yesAdvanced Science, EarlyView.
A multifunctional mercaptosuccinic acid enables an ultrathin organic–inorganic SEI (Zn‐S‐RCOOH) that synergistically regulates interfacial water and accelerates Zn2+ transport. The optimized hydrogen‐bond environment and ZnS‐guided deposition suppress dendrites, corrosion, and by‐product formation, delivering ultrastable Zn cycling and high‐performance
