Abstract

A non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery including the same are provided. The non-aqueous electrolyte solution includes an organic solvent, an ionizable lithium salt, a dinitrile compound including an ether bond represented by Chemical Formula 1, and an aliphatic dinitrile compound represented by Chemical Formula 2. The lithium secondary battery including the non-aqueous electrolyte solution having the possibility of generating a swelling phenomenon while storing or charging/discharging at a high temperature may be restrained. In addition, a cycle life of the charging/discharging may be improved.
