In view of the advantages low cost, environmental sustainability, and high safety, aqueous Zn-ion batteries (AZIBs) are widely expected to hold significant promise increasingly infiltrate various applications in near future. The development AZIBs closely relates properties cathode materials, which depend on their structures corresponding dynamic evolution processes. Synchrotron radiation light sources, with rich advanced experimental methods, serve as a comprehensive characterization platform capable elucidating intricate microstructure materials for AZIBs. this review, we initially examine available discuss effective strategies structural regulation boost storage capability Zn2+. We then explore synchrotron techniques investigating designed particularly through situ that can track process structures. Finally, summary future prospects further discussed.

Abstract Aqueous ammonium ion batteries (AAIBs) have garnered significant attention due to their unique energy storage mechanism. However, progress is hindered by the relatively low capacities of NH 4 + host materials. Herein, study proposes an electrodeposited tungsten oxide@polyaniline (WO x @PANI) composite electrode as a host, which achieves ultrahigh capacity 280.3 mAh g −1 at 1 A , surpassing vast majority previously reported The synergistic interaction coordination chemistry and hydrogen bond between WO PANI enhances charge capacity. Experimental results indicate that strong interfacial bonding (N: →W 6+ ) effectively modulates chemical environment W atoms, protonation level PANI, thus consequently conductivity stability composites. Spectroscopy analysis further reveals /H co‐insertion mechanism, in network (N‐H···O) accelerates proton involvement process activates Grotthuss hopping conduction H hydrated oxide layers. This work opens new avenue achieving high‐capacity through interactions, overcoming limitations materials for aqueous storage.

Layered Iron Vanadate for High‐Performance and Stable Cathode Material for Aqueous Manganese Batteries

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Апрель 7, 2025

Abstract Aqueous rechargeable metal batteries have gained significant attention because of the low cost, high capacity, and inherent safety offered by nonflammable water‐based electrolytes. Among these, Mn‐based systems are promising owing to their intrinsic stability, abundance, affordability, energy density. Despite these advantages, development suitable host structures for Mn storage remains underexplored. This study introduces layered iron vanadate, FeV 3 O 9 ·1.1H 2 O, as a new cathode material aqueous batteries, demonstrating exceptional performance. The exhibits reversible capacity 306.9 mAh g −1 at 0.25 A an excellent rate performance 210.6 . In addition, outstanding cycling retaining 73.4% its initial after 3000 cycles − ¹, which is attributed volume expansion. underlying reaction mechanism elucidated through spectroscopic microscopic analyses. When integrated into final cell, system demonstrates superior compared Zn underscoring potential next‐generation battery systems. These findings advance technology, paving way safer, more cost‐effective, high‐performance solutions.
