Title:
SECONDARY BATTERY SOLID ELECTROLYTE COMPOSITION AND SOLID ELECTROLYTE PREPARED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2019/054622
Kind Code:
A1
Abstract:
The present invention relates to: a lithium secondary battery solid electrolyte composition in which an alkylene oxide and a monomer containing a cross-linking functional group are grafted on a fluorine-based polymer; and a secondary battery solid electrolyte formed by thermosetting the composition. The present invention can provide a secondary battery solid electrolyte having greatly improved ion conductivity and electrochemical stability, by graft-copolymerizing an alkylene oxide and a monomer containing a cross-linking functional group onto a fluorine-based polymer having a high lithium ion conductivity.
