All-solid-state sodium batteries (ASSSBs) are viable candidates for large scale energy storage that could vie with lithium. Ductile solid catholytes such cells can be prepared without extensive ball milling and directly paired high voltage cathodes lacking, however. We report a new amorphous fast Na-ion conducting metal oxychloride meets these criteria, synthesized through scalable low-cost route based on spontaneous solid-state reaction simple short mixing 100 °C annealing. It has an ionic conductivity of 1.2 mS·cm–1 low activation 0.31 eV. Due to its dual O2–/Cl– framework, it exhibits anodic potential 4 V vs Na+/Na good chemical/electrochemical compatibility cathode materials. ASSSBs consisting the electrolyte P2–Na2/3Ni1/3Mn2/3O2 showed stable long-term cycling 4.0 Na3Sn cutoff even 4.3 V.

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.

LiMXCl4 is a recently discovered lithium superionic conductor reported with Li conductivity up to 12.4 mS/cm at room temperature. In this work, we explore various types of M-cation and X-anion substitutions in the system. We find that fluoro-chlorides may provide promising thermodynamic electrochemical stability without compromising ionic conductivity. Ab-initio molecular dynamics simulations on seven three concentrations for each substitution suggest even higher be achieved than has been reported. A Meyer-Neldel analysis comparing LiMXCl4, close-packed halides, LaCl3-type systems demonstrates potential family due their high energy, prefactor, low activation projecting range 10-100 mS/cm. An correlation between lithium-ion hops small-angle tilting events finds exhibit strong cradle effect where weakly bound M-octahedra often tilt orientation conjunction nearby Li-ion hop flatten energy landscape. Such an advantage originates from fact structure, one-dimensional M-octahedral chains are via weak van der Waals interactions which can accommodate reduction free volume rotational octahedra. Our work exciting direction towards further improving class materials terms provides fundamental understanding factors lead non-close-packed oxyhalide systems.

Abstract The ability to rapidly charge batteries is crucial for widespread electrification across a number of key sectors, including transportation, grid storage, and portable electronics. Nevertheless, conventional Li‐ion with organic liquid electrolytes face significant technical challenges in achieving rapid charging rates without sacrificing electrochemical efficiency safety. Solid‐state (SSBs) offer intrinsic stability safety over their counterparts, which can potentially bring exciting opportunities fast applications. Yet realizing fast‐charging SSBs remains challenging due several fundamental obstacles, slow Li + transport within solid electrolytes, sluggish kinetics the electrodes, poor electrode/electrolyte interfacial contact, as well growth dendrites. This article examines SSB through comprehensive review materials strategies (ceramics, polymers, composites), composites. In particular, methods enhance ion crystal structure engineering, compositional control, microstructure optimization are analyzed. also addresses interface/interphase chemistry mechanisms, providing insights guide material design interface next‐generation SSBs.
