· JVASP-36561· NaLi2As

NaLi₂As is an experimental ceramic compound composed of sodium, lithium, and arsenic, belonging to the family of ternary metal arsenides. This material is primarily of research interest for solid-state chemistry and materials discovery rather than established industrial production. Its potential applications lie in energy storage systems (particularly solid-state batteries leveraging lithium content), thermoelectric devices, and semiconductor research, where ternary arsenide compounds are investigated for their electronic and ionic transport properties.
