Abstract
A non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery including the same are disclosed herein. In an embodiment, the electrolyte solution includes a lithium salt, an organic solvent, a compound represented by Formula 1 as a first additive, lithium difluorophosphate (LiDFP) as a second additive, wherein the first additive and the second additive are each independently included in an amount of 0.01 wt % to 8.5 wt % based on a total amount of the non-aqueous electrolyte solution. The first additive has metal ion adsorbability and is capable of forming a stable ion conductive film on the surface of an electrode, and a lithium secondary battery in which an abnormal voltage drop phenomenon is improved by including the same.
