Abstract
A non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery including the same are disclosed herein. In some embodiments, a non-aqueous electrolyte solution includes a lithium salt, a fluorine-based linear ether solvent, a fluorine-based cyclic carbonate solvent, and a fluorine-based lithium compound, 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. In some embodiments, a lithium secondary battery having the non-aqueous electrolyte solvent has improved high-temperature storage characteristics.
