Li2Fe2S3
metal· JVASP-50619· Li2Fe2S3
Li2Fe2S3 is an iron-lithium sulfide compound belonging to the family of lithium-iron chalcogenides, currently investigated primarily as a research material rather than an established commercial product. This material is of interest in solid-state battery and energy storage applications, where lithium-iron sulfides are explored as potential cathode or electrolyte components due to their mixed-valent iron chemistry and ionic conductivity characteristics. The compound represents an experimental avenue in next-generation battery chemistry, competing with conventional layered oxides and emerging alternatives as researchers seek higher energy density and alternative electrochemical platforms.
