· JVASP-153815· LiAlS2

LiAlS2 is an experimental lithium-aluminum sulfide compound that belongs to the family of sulfide-based solid electrolytes and functional ceramics. This material is primarily investigated in energy storage research, particularly for all-solid-state battery applications where its ionic conductivity and chemical stability are of interest. LiAlS2 represents a class of alternative electrolyte materials being explored to overcome limitations of conventional liquid electrolytes, making it relevant for engineers developing next-generation energy storage systems requiring high energy density, improved safety, or extended cycle life.
