A solid electrolyte membrane for an all-solid-state battery, comprising a guide layer, wherein the solid electrolyte membrane comprises a solid electrolyte material and metal particles, and the metal particles can form an alloy with lithium during operation of the battery, and the guide layer is disposed in a layer shape within the solid electrolyte membrane, and the metal particles are included in the guide layer. 2 . The solid electrolyte membrane for an all-solid-state battery according to claim 1 , wherein the metal particles have Li metal nucleation overpotential of 100 mV or less. 3 . The solid electrolyte membrane for an all-solid-state battery according to claim 1 , wherein the solid electrolyte membrane comprises at least one selected from the group consisting of Au, Ag, Pt, Zn, Mg, Al, Ni and Bi as the metal particles. 4 . The solid electrolyte membrane for an all-solid-state battery according to claim 1 , wherein the guide layer is 1 nm to 1,000 nm in thickness. 5 . The solid electrolyte membrane for an all-solid-state battery according to claim 1 , wherein the solid electrolyte material comprises a polymer-based solid electrolyte material. 6 . The solid electrolyte membrane for an all-solid-state battery according to claim 5 , wherein the polymer-based solid electrolyte material comprises a polymer resin and a lithium salt, and exhibits ionic conductivity of 1×10 −7 S/cm or above. 7 . The solid electrolyte membrane for an all-solid-state battery according to claim 1 , wherein the metal particles have a particle size of 1 nm to 5 μm. 8 . The solid electrolyte membrane for an all-solid-state battery according to claim 1 , wherein the metal particles are present in an amount of 0.1 wt % to 20 wt % based on 100 wt % of the solid electrolyte membrane. 9 . An all-solid-state battery comprising the solid electrolyte membrane according to claim 1 . 10 . The all-solid-state battery according to claim 9 , wherein the all-solid-state battery comprises a negative electrode comprising a lithium metal as a negative electrode active material or a current collector with no negative electrode active material. 11 . The all-solid-state battery according to claim 9 , wherein the all-solid-state battery comprises a negative electrode, a positive electrode and a solid electrolyte membrane, the solid electrolyte membrane is interposed between the negative electrode and the positive electrode, at least one of the negative electrode and the positive electrode comprises a solid electrolyte material, and the solid electrolyte material comprises at least one of a polymer-based solid electrolyte, an oxide-based solid electrolyte and a sulfide-based solid electrolyte.
