Title:
POLYMER SOLID ELECTROLYTE AND ALL-SOLID-STATE BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/090905
Kind Code:
A1
Abstract:
The present invention relates to a polymer solid electrolyte and an all-solid-state battery comprising same, and more specifically, the present invention may provide a polymer solid electrolyte having safety and ionic conductivity improved simultaneously by means of a cross-linking structure formed by means of cross-linking between a solid cross-linking agent and/or a cross-linkable functional group contained in polyhedral oligomeric silsesquioxane.
