Abstract: Provided are a sulfide-based lithium-argyrodite ion superconductor containing multiple chalcogen elements and a method for preparing the same. More specifically, provided are a sulfide-based lithium-argyrodite ion superconductor containing multiple chalcogen elements and a method for preparing the same that are capable of significantly improving lithium ion conductivity by substituting a sulfur (S) element in a PS43- tetrahedron with a chalcogen element such as a selenium (Se) element, other than the sulfur (S) element, while maintaining an argyrodite-type crystal structure of a sulfide-based solid electrolyte represented by Li6PS5Cl.
