Abstract
Disclosed is a sulfide-containing solid electrolyte material with an organic coating, as well as densified pellets containing this solid electrolyte material, a solid electrolyte thereof, and a solid state battery containing the solid electrolyte. According to aspects of the disclosure, the coating comprising a compound of Chemical Formula (1) or Chemical Formula (2) is formed on the surface of a sulfide-containing solid electrolyte material, e.g., the organic coating may comprise a compound having a thiol with a long hydrophobic tail, such as 1-undecanethiol. The coating provides densification of sulfide-containing solid electrolyte materials, and facilitates the ionic and lithium atomic diffusion coefficient at sulfide grain boundaries during pressing, thus achieving the densification of sulfide solid state electrolyte.
