Title:
POLYMER FOR GEL POLYMER ELECTROLYTE, AND GEL POLYMER ELECTROLYTE AND LITHIUM SECONDARY BATTERY, EACH COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/025544
Kind Code:
A1
Abstract:
The present invention relates to a polymer for a gel polymer electrolyte and a gel polymer electrolyte and a lithium secondary battery, each comprising same. More specifically, the polymer for a gel polymer electrolyte has a fluorine-based polymer backbone grafted with a siloxane group-bearing side chain and an acryl-based polymer-bearing side chain and can improve stability in the gel polymer electrolyte and the lithium secondary battery, each comprising the polymer for a gel polymer electrolyte.
