· JVASP-101487· K2LiAsF6

K2LiAsF6 is a mixed-cation fluoroarsenate ceramic compound combining potassium, lithium, and arsenic fluoride anions in a crystalline structure. This material is primarily of research interest for solid-state electrochemistry and advanced functional ceramics applications, particularly in ionic conductivity studies and potential solid electrolyte development for next-generation battery systems. Its dual-cation composition and fluoride-based framework make it notable in the family of superionic conductors, where lithium mobility through the crystal structure is leveraged for energy storage and ion transport applications.
