Abstract: Disclosed is a solid electrolyte for a solid-state battery having improved water resistance. The solid electrolyte for a solid-state battery includes a sulfide-based solid electrolyte and a LiBr-containing absorbent material, wherein the binding energy of Li1s shows a peak observed at 54.2-56.1 eV, and the binding energy of Br3d shows a peak observed at 67.5-69.5 eV, as determined by X-ray photoelectron spectroscopy (XPS).
