· Li0.5Pb1.75GeS4

Li₀.₅Pb₁.₇₅GeS₄ is a mixed-cation chalcogenide semiconductor compound combining lithium, lead, germanium, and sulfur in a single-phase crystal structure. This material belongs to the family of superionic or solid-state ionic conductors and is primarily studied in research contexts for its potential as a solid electrolyte material. The lead-germanium sulfide framework doped with lithium offers promise for all-solid-state battery applications and advanced ionics research, where high lithium-ion conductivity and electrochemical stability are critical advantages over traditional liquid electrolytes.
