An electrolyte solution for a lithium secondary battery includes an organic solvent, a lithium salt, and a fluorine-based additive in which a terminal difluoro-phosphite group (—OPF
2
) is bonded to a branched saturated hydrocarbon group. The fluorine-based additive prevent side reactions in the electrolyte solution to improve stability of a cathode active material.
