Discoveries and technological innovations over the past decade are transforming our understanding of properties ceramics, such as 'hard', 'brittle', 'homogeneous'. For example, inorganic crystals containing molecular anions exhibit excellent secondary battery characteristics, fusion solids molecules results in innovative catalytic functions physical properties. Different from conventional ceramics metal oxides that formed by monatomic cations anions, unique can be expected molecular-incorporated solids, due to asymmetric dynamic brought about constituent units.

Опубликована: Янв. 13, 2025

All-solid-state fluoride-ion batteries (FIBs) have attracted extensive attention as candidates for next-generation energy storage devices; however, promising cathodes with high density are still lacking. In this study, Cu3N is investigated a cathode material all-solid-state batteries, which offers enough anionic vacancies around the 2-fold coordinated Cu center F- intercalation, thereby enabling multielectron-transferred fluorination process. The contribution of both cationic and redox to charge compensation, in particular, generation molecular nitrogen species highly charged states, has been proved by several synchrotron-radiation-based spectroscopic technologies. As result, exhibits reversible capacity ∼550 mAh g-1, exceeding many conventional cathodes. It believed that new compensation chemistry well unique intercalation behaviors novel mixed-anion Cu-N/F local structures could bring insights into materials.

Revealing the Unusual Mechanism of Mixed Cationic and Anionic Redox in Oxyfluorosulfide Cathode for All-Solid-State Fluoride-Ion Batteries

Chemistry of Materials, Год журнала: 2024, Номер 36(4), С. 1928 - 1940

Опубликована: Фев. 14, 2024

All-solid-state fluoride-ion batteries (FIBs) have been considered next-generation energy storage devices because of their high theoretical density. However, previously reported metal/metal fluoride active materials suffer from severe degradation due to large volume expansion; consequentially, fluoride-ion-intercalating fail deliver a capacity. Here, oxyfluorosulfide Sr2F2Fe2OS2 (SFFOS) with layer structure is as topotactic (de)intercalation host. This material delivers reversible capacity more than 340 mAh g–1, which remains well maintained after 20 cycles. The intercalation reaction mechanism for this and stable elucidated via X-ray diffraction fine analysis. Wherein both Fe2+/Fe3+ redox sulfide ion are involved in charge compensation during charge/discharge processes, where the contributes whole voltage range −1.5 1.5 V only middle state charge. Fluoride ions can not insert into Sr–S interstitial sites but also combine Fe cations. Meanwhile, excessive leads formation S–S bonds SFFOS lattice. These results highlight oxyfluorosulfides new class constructing high-performance FIBs.

Mixed-anion compounds have recently attracted attention as solid-state materials that exhibit properties unattainable with those of their single-anion counterparts. However, the use mixed-anion to control morphology and engineer crystal facets electrocatalysts has been limited because synthesis method is still immature. This study explored electrocatalytic a Pb–Fe oxyfluoride, Pb3Fe2O5F2, layered perovskite structure for oxygen evolution reaction (OER) compared its in detail bulk-type cubic three-dimensional (3D) perovskite, PbFeO2F. A Pb3Fe2O5F2 electrode prepared carbon nanotubes graphite sheet conductive support substrate, respectively, demonstrated better OER performance than PbFeO2F electrode. The role specific enhancing activity was elucidated through electrochemical analysis. Density functional theory calculations indicated (060) facet Fe sites exhibited lower theoretical overpotential OER, which attributed moderately strong interaction between active intermediates; this reinforced by electron-withdrawing behavior fluoride ions. finding offers new insights developing efficient based on oxyfluorides, leveraging high electronegativity fluorine optimize electronic states at without relying precious metals.

All-solid-state fluoride-ion batteries (FIBs) are considered as a promising alternative to lithium-ion (LIBs) for next-generation energy storage devices. Intercalation-type cathode materials FIBs have been developed in the past. However, they limited by low theoretical capacities, which fail meet high density and rate capability demand. This study reports first application of intercalation-type material CuLaO2 all-solid-state FIBs. maintains capacity 184 mAh g–1 over 50 cycles. Compared metal/metal fluoride (M/MFx) reported so far, exhibits an outstanding with 102 even at current 200 mA g–1. Electrochemical measurements, coupled X-ray absorption spectroscopy diffraction prove that charge/discharge processes proceed via intercalation reaction reversible phase transition between crystalline/amorphous phases, charge compensation is responsible multielectron redox Cu+/Cu3+. We believe this can bring insight into
