Abstract
The present invention relates to a non-aqueous electrolyte solution additive, and a non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery which comprise the same, wherein, specifically, since the non-aqueous electrolyte solution, which comprises a compound capable of maintaining a passive effect by increasing an effect of forming a solid electrolyte interface (SEI) on surfaces of a positive electrode and a negative electrode, is provided, high-temperature storage characteristics and life characteristics of the lithium secondary battery may be improved.
