Abstract
Disclosed is a method for manufacturing a solid electrolyte membrane for a solid-state battery and a solid electrolyte membrane obtained thereby. The solid electrolyte membrane for a solid-state battery includes a heat treated porous polymer sheet and a solid electrolyte material, wherein solid electrolyte material and the porous polymer sheet form a composite in such a manner that the pores of the porous polymer sheet is filled with the solid electrolyte material. In this manner, it is possible to provide a solid electrolyte membrane for a solid-state battery which has high mechanical strength and high ion conductivity.
