Abstract: A flexible self-supporting solid electrolyte membrane, an all-solid-state battery including the membrane, and a manufacturing method thereof are disclosed. The solid electrolyte membrane may include: a substrate including pores therein; and a solid electrolyte layer disposed on at least one surface of the substrate and including a solid electrolyte and a cured compound. At least a portion of the solid electrolyte layer may penetrate into the pores of the substrate to form a conduction path of lithium ions in a thickness direction of the substrate.

Abstract: Disclosed are a method and an apparatus of manufacturing an anode for an all-solid-state battery by using an electric field. The manufacturing method includes: preparing a first coating member and a second coating member spaced apart from the first coating member by a predetermined distance; preparing a coating slurry, the coating slurry including a carbon material and a metal alloyable with lithium; feeding the coating slurry to the first coating member; feeding a current collector between the first coating member and the second coating member; and coating the coating slurry on the current collector by using an electric field generated between the first coating member and the second coating member by applying voltages to the first coating member and the second coating member.
