Title:
NON-AQUEOUS ELECTROLYTE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/103112
Kind Code:
A1
Abstract:
The present invention provides a non-aqueous electrolyte for a lithium secondary battery and a lithium secondary battery comprising same. Specifically, the non-aqueous electrolyte for a lithium secondary battery comprises a lithium salt, an organic solvent, and a compound represented by chemical formula 1, whereby a robust SEI film is formed and thus the performance of a battery can be improved.
