Title:
SOLID POLYMER ELECTROLYTE AND ALL-SOLID-STATE BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/080809
Kind Code:
A1
Abstract:
The present invention relates to a solid polymer electrolyte and an all-solid-state battery. The solid polymer electrolyte comprises a polymer containing a polyethylene oxide (PEO)-based copolymer with crosslinkable functional groups; and a polar compound, wherein at least some of the crosslinkable functional groups form crosslinks with each other, enabling the polymer to form a three-dimensional network structure, and the polar compound is either contained within the three-dimensional network structure in a gaseous state or bound to the polymer chains, fulfilling certain specified characteristics.
