Non-Aqueous Electrolyte Solution for Lithium Secondary Battery and Lithium Secondary Battery Including the Same

Abstract

Provided are a non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery including the same and having improved high-temperature storage characteristics and high-temperature cycle characteristics. Specifically, the non-aqueous electrolyte solution may comprise a lithium salt, an organic solvent and a compound represented by Formula 1 as a first additive: wherein Formula 1, Ar is a 5-membered or 6-membered nitrogen-containing ring, and R1 and R2 are each independently an alkyl group having 1 to 8 carbon atoms.

Dependencies are inferred from the claim text.
