Non-aqueous electrolyte solution for lithium secondary battery and lithium secondary battery including the same

A non-aqueous electrolyte solution for a lithium secondary battery, the non-aqueous electrolyte solution comprising:

• a lithium salt;
• a fluorine-based linear ether solvent represented by Formula 1;
• a fluorine-based cyclic carbonate solvent;
• and
• a fluorine-based lithium compound represented by Formula 2a,
• wherein the fluorine-based linear ether solvent and the fluorine-based cyclic carbonate solvent are present in a weight ratio of 6:4 to 9:1,
• R1—O—R2 [Formula 1]
• wherein, in Formula 1,
• R1 and R2 are each independently an alkyl group having 1 to 10 carbon atoms which is unsubstituted or substituted with fluorine, wherein at least one of R1 and R2 is an alkyl group having 1 to 10 carbon atoms which is substituted with fluorine,
