Title:
ELECTROLYTE COMPOSITION FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/108035
Kind Code:
A1
Abstract:
The present invention relates to a thermosetting electrolyte composition for a lithium secondary battery, and a lithium secondary battery comprising the same. More particularly, the present invention relates to a thermosetting electrolyte composition for a lithium secondary battery, and a lithium secondary battery comprising the same, the composition comprising LiPF6 as a first lithium salt, a non-aqueous organic solvent, and a polymer or oligomer comprising a unit represented by formula 1, wherein the polymer or oligomer comprising the unit represented by formula 1 is contained in an amount of 0.6 to 15% by weight on the basis of the total weight of the thermosetting electrolyte composition for a lithium secondary battery.
