Article Synopsis
- The study successfully synthesized a new compound, γ-LiScCl, under high pressure, marking the first time this has been achieved for this family of ionic conductors.
- Structural analysis revealed that γ-LiScCl exhibits a unique hexagonal close-packed (hcp) arrangement of anions, unlike its previously known cubic closed-packed (ccp) forms.
- The research highlights that the ratio of cation to anion radii is crucial for determining the structural formation and that γ-LiScCl demonstrates enhanced electrochemical stability, suggesting potential advancements in the design of lithium solid electrolytes.
The thermal conductivity above room temperature is investigated for LaCoO-based materials showing spin-state and insulator-metal crossovers. A positive temperature coefficient (PTC) of the thermal conductivity is observed during the insulator-metal crossover around 500 K. Our analysis indicates that the phononic thermal transport is also enhanced in addition to the electronic contribution as the insulator-metal crossover takes place.
