Calcium vapor synthesis of extremely coercive SmCo.

Exceptionally coercive SmCo particles are produced through calcium vapor reduction of SmCoO powders synthesized by flame spray pyrolysis. The resulting powders are composed of oblate hexagonal particles approximately 2 microns across with smooth surfaces. This microstructure yields record-breaking room temperature coercivity >80 kOe, or >60 kOe when combined with advanced manufacturing approaches such as electrophoretic deposition or molding with tetraglyme inks.

Cathode Interface Compatibility of Amorphous LiMnO (LMO) and LiLaZrO (LLZO) Characterized with Thin-Film Solid-State Electrochemical Cells.

Solid-state lithium-ion batteries are a hopeful successor to traditional Li-ion cells that use liquid electrolytes. While a growing body of work has characterized the interfaces between various solid electrolytes and the lithium metal, interfaces with common cathode intercalation compounds are comparatively less understood. In this contribution, the influence of polarization and temperature on interfacial stability between LiMnO (LMO) and LiLaZrO (LLZO) are investigated.
