SOLID ELECTROLYTE, METHOD FOR PREPARING SAME, AND ALL-SOLID-STATE BATTERY INCLUDING SAME

Document Type and Number:

WIPO Patent Application WO/2020/045893

Kind Code:

A1

Abstract:

The present invention relates to a solid polymer electrolyte and a method for preparing same. More specifically, the present invention relates to a solid polymer electrolyte and a method for preparing same, the solid polymer electrolyte comprising a multifunctional acrylate-based polymer, C1 to C10 polyalkyleneoxide, a flame retardant polymer, a lithium salt, and a non-aqueous solvent, wherein the multifunctional acrylate-based polymer crosslinks with the polyalkyleneoxide so as to form semi-interpenetrating polymer networks (semi-IPNs), and the flame retardant polymer is blended with the semi-interpenetrating polymer networks of the multifunctional acrylate-based polymer and the polyalkyleneoxide so as to exhibit a high content of solids and flame retardant properties.
