Halogen-Substituted LiInCl: Insights into the Evolved Structure, Composition, and Ionic Conductivity.

Ternary Li-containing halides have gained significant interest for all-solid-state batteries because they show high Li-ion conductivity and their structures can be modified. In this study, halogen substitution in LiInCl was attempted to form LiInCl ( = F, Br, I) samples whose phase compositions and Li conductivity were characterized by X-ray diffraction and impedance spectroscopy. Based on the evolution of cell parameters, Cl can be substituted by F within the experimental limit of ≤ 1.

Cellulose-Encapsulated Composite Electrolyte Design: Toward Chemically and Mechanically Enhanced Solid-Sodium Batteries.

Sulfide- and halide-based ceramic ionic conductors exhibit comparable ionic conductivity with liquid electrolytes and are candidates for high-energy- and high-power-density all-solid-state batteries. These materials, however, are inherently brittle, making them unfavorable for applications. Here, we report a mechanically enhanced composite Na conductor that contains 92.

Are Selenides the Same as Sulfides? Structure, Spectroscopy, and Properties of Narrow-Gap Rare-Earth Semiconductors Sn(SSe) ( = La, Ce; = 0-0.8).

The ternary rare-earth sulfides SnS ( = La-Nd) and the partial solid solutions Sn(SSe) ( = La, Ce; = 0-0.8) were prepared in the form of polycrystalline samples by reaction of the elements at 900 °C and as single crystals in the presence of KBr flux. They adopt the LaSnS-type structure (orthorhombic, space group , = 2) consisting of chains of edge-sharing Sn octahedra separated by atoms.

Mechanochemistry in Sodium Thioantimonate Solid Electrolytes: Effects on Structure, Morphology, and Electrochemical Performance.

Sodium thioantimonate (NaSbS) and its W-substituted analogue NaSbWS have been identified as potential electrolyte materials for all-solid-state sodium batteries due to their high Na conductivity. Ball milling mechanochemistry is a frequently employed synthetic approach to produce such Na-conductive solid solutions; however, changes in the structure and morphology introduced in these systems via the mechanochemistry process are poorly understood. Herein, we combined X-ray absorption fine structure spectroscopy, Raman spectroscopy, solid-state nuclear magnetic resonance spectroscopy, powder X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy characterization techniques to provide an in-depth analysis of these solid electrolytes.

An NHC-Stabilized H GeBH Precursor for the Preparation of Cationic Group 13/14/15 Hydride Chains.

The synthesis, characterization and reactivity studies of the NHC-stabilized complex IDipp ⋅ GeH BH OTf (1) (IDipp=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) are reported. Nucleophilic substitution of the triflate (OTf) group in 1 by phosphine or arsine donors provides access to the cationic group 13/14/15 chains [IDipp ⋅ GeH BH ERR R ] (2 E=P; R, R =H; R = Bu; 3 E=P; R=H; R , R =Ph; 4 a E=P; R, R , R =Ph; 4 b E=As; R, R , R =Ph). These novel cationic chains were characterized by X-ray crystallography, NMR spectroscopy and mass spectrometry.
