A non-aqueous electrolyte solution includes an electrolyte solution including an amide compound and a lithium salt, and a dinitrile compound substituted by a hetero atom at a main chain, and a lithium secondary battery includes the non-aqueous electrolyte solution. By using the non-aqueous electrolyte solution, a lithium secondary battery having an improved swelling phenomenon and an increased charging/discharging performance may be provided. |
