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 for a lithium secondary battery, includes an additive having metal ion adsorbability and capable of forming a stable ion conductive film on the surface of an electrode. In some embodiments, a lithium secondary battery including the same has an improved an abnormal voltage drop phenomenon.
