In the sulfide solid electrolyte, the halogen atoms include i) chlorine and ii) at least two selected from bromine, iodine, and fluorine; an atomic ratio of sulfur to oxygen (S/O) in the sulfide solid electrolyte is about 4 or higher, and an atomic ratio of chlorine (CI) to the at least two selected from bromine, iodine, and fluorine (X) (CI/X) is about 9 or higher.",
