· Li1 Co1 S2

Lithium cobalt disulfide (LiCoS₂) is a layered transition metal chalcogenide semiconductor compound combining lithium, cobalt, and sulfur in a 1:1:2 stoichiometry. This material is primarily investigated in research contexts for energy storage and electrochemical applications, particularly as a cathode material or electrode component where its layered crystal structure facilitates ion intercalation and electron transport. The compound represents an experimental alternative within the family of lithium-based metal sulfides, offering potential advantages for next-generation battery chemistries and solid-state device applications where conventional oxide cathodes have limitations.
