Solid electrolytes, as the core of all-solid-state batteries (ASSBs), play a crucial role in determining kinetics ion transport and interface compatibility with cathodes anodes, which can be subdivided into catholytes, bulk anolytes based on their functional characteristics. Among various inorganic solid ductile distinguished from rigid oxide exhibit excellent properties even under cold pressing, thus holding greater promise for industrialization. However, challenge lies finding electrolyte that simultaneously serve catholyte, electrolyte, anolyte. Fortunately, due to immobility combining multiple types electrolytes allows leveraging respective advantages. In this review, we discuss five sulfides, halides, nitrides, antiperovskite-type, complex hydrides, challenges superiorities these are also addressed. The impact pressure ASSBs has been systematically discussed. Furthermore, suitability anolyte is discussed characteristics physicochemical properties. This discussion aims deepen our understanding enabling us harness advantages develop practical, high-performance ASSBs.

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 6, 2025

Ultra-high nickel layered oxides are recognized as promising cathode candidates for high-energy-density lithium-ion batteries due to their enhanced overall capacity and elevated operating voltage. However, the interlayer sliding of transition metal-oxygen octahedra (TMO6) instability lattice oxygen at high voltages ultra-high oxide cathodes pose significant challenges development. Herein, origin framework stability is investigated by incorporating high-covalent element Mo in both bulk surface using a one-step integrated method material LiNi0.92Co0.08O2. It revealed that apart from isolation protection effect Mo-enriched layer, suppression Li/Ni antisite defects Mo6+ with strong covalency plays critical role reducing configurations activated anionic redox reaction stabilizing structure. Benefiting this, reversibility significantly enhanced, enabling more oxidized exist form dimer ions O2n-$O_2^{n - }$ rather than being lost gaseous O2. Consequently, modified demonstrates improved diffusion kinetics optimized electrochemical performance

Metastable LaOClx Phase Stabilization as an Effective Strategy for Controllable Chlorination of Ethane into 1,2-Dichloroethane

Molecules, Journal Year: 2025, Volume and Issue: 30(8), P. 1746 - 1746

Published: April 14, 2025

LaOCl-mediated ethane chlorination into 1,2-dichloroethane offers a promising pathway for low-temperature, large-scale upgrading. However, under Cl2-rich conditions, LaOCl undergoes detrimental lanthanum chloride (LaCl3), accompanied by extensive surface hydroxylation. Such severe structural evolution limits the practical application of La-based catalysts industrially relevant conditions. In this study, an alumina-stabilized La catalyst was prepared via coprecipitation method. We demonstrated that strong La-O-Al interactions effectively resist degradation species reaction enabling modified to maintain exceptional stability high Cl2 concentrations. At C2H6/Cl2 ratio 4:9, optimized achieves conversion 61%, with selectivity sustained above 74% 12 h without noticeable deactivation. contrast, bulk counterpart suffers from rapid over-chlorination, shifting product dominance trichloroethane within 10 h. Advanced spectroscopy characterization reveals loss in originates phase collapse LaCl3, whereas Al2O3 stabilization preserves metastable LaOClx highly dispersed state, ensuring selective C–Cl bond formation. These results highlight critical role stabilizing oxychloride phases through robust metal oxide interactions, establishing design framework rare-earth high-concentration chlorine environments.
