Solid Electrolyte Electrode Composite, Method For Manufacturing Solid Electrolyte Electrode Composite, And All Solid State Battery Comprising Same Solid Electrolyte Electrode Composite

Abstract: The present invention relates to a method for manufacturing a solid electrolyte-electrode composite, a solid electrolyte-electrode composite, and an all-solid-state battery comprising the solid electrolyte-electrode composite, the method comprising the steps of: impregnating an electrode with an electrolyte precursor composition comprising a photo-crosslinkable monomer containing three or more acrylate groups, an initiator, a lithium salt, and an organic solvent; forming a polymer electrolyte membrane by photocuring the electrode impregnated with the electrolyte precursor composition; and thermosetting the electrode on which the polymer electrolyte membrane is formed, and the solid electrolyte-electrode composite having no peak in a wavenumber range of 1,700 cm-1 to 1,600 cm-1 in Fourier transform infrared spectroscopy.
