· Li6 P1 S5 I1

Li₆PS₅I is a lithium-rich halide-based solid electrolyte compound belonging to the argyrodite family of superionic conductors. This material is primarily of research and development interest rather than established commercial use, being investigated as a promising solid-state electrolyte for next-generation lithium-ion and lithium-metal batteries. The iodine substitution in the PS₅ framework aims to enhance ionic conductivity and mechanical stability compared to purely sulfide-based electrolytes, making it relevant for high-energy-density battery applications where conventional liquid electrolytes present safety and thermal limitations.
