General description

Lithium phosphorus sulfur chloride (LPSCl) is a light brown powder that features high ionic conductivity. LPSCl belongs to the Argyrodite-type crystal structure, which is a type of cubic close-packed structure, and facilitates fast lithium-ion diffusion. LPSCl has a molecular weight of 268.40 g/mol and a density of 1.64 g/cm3 (lit.). Importantly, LPSCl is compatible with lithium metal anodes.

Application

Lithium phosphorus sulfur chloride is primarily used as a solid-state electrolyte for lithium-ion batteries due to its high ionic conductivity, high thermal stability, wide electrochemical window, and compatibility with lithium metal anodes. With the growing demand for high-performance batteries for use in electric vehicles, portable electronics, and other applications, Li6PS5Cl is positioned to play a key role in the future of battery technology. Its ability to enable the use of lithium metal anodes and solid-state electrolytes makes it an essential material for the development of next-generation batteries that offer increased energy efficiency, longer lifetimes, and improved safety.
