Title:

METHOD FOR PRODUCING POLYMER SOLID ELECTROLYTE

Document Type and Number:

WIPO Patent Application WO/2024/080808

Kind Code:

A1

Abstract:

The present invention relates to a method for producing a polymer solid electrolyte. The method for producing the polymer solid electrolyte includes the steps of: (S1) preparing a polymer in which a polyethylene oxide (PEO)-based copolymer containing a cross-linkable functional group is cross-linked; and (S2) vapor-depositing a polar solvent on the polymer prepared in step (S1), wherein the vapor-deposition step may be performed to satisfy a predetermined relational expression, thereby controlling the content of a polar compound in the polymer solid electrolyte.
