Solid electrolyte membrane, method for manufacturing same, and method for selecting solid electrolyte membrane

Abstract

Methods for manufacturing a solid electrolyte membrane are provided, which allow visual determination of how much a porous sheet is filled with a solid electrolyte material, and thus can optimize selection of materials and manufacturing processes of a solid electrolyte membrane in a simple manner. The resulting solid electrolyte membrane can reduce the manufacturing cost and allow easy deformation, and thus can be processed with ease when it is applied to batteries having various shapes. Further, since the solid electrolyte membrane according to the present disclosure includes a composite of a porous polymer material, such as a nonwoven web, with a solid electrolyte material, it has excellent strength and allows formation of a thin film, and thus provides a battery with improved energy density advantageously.
