摘要： A lithium secondary battery includes: a negative electrode including a silicon-based negative electrode active material; a positive electrode; a separator; and a non-aqueous electrolyte. The non-aqueous electrolyte contains: a lithium salt; an organic solvent; a compound of Formula 1 as a first additive; and a compound of Formula 2 as a second additive.
Here, R is an alkylene group with 1 to 5 carbon atoms, which is substituted with fluorine, and R1 to R3 are each independently any one selected from the group consisting of H, an alkyl group with 1 to 5 carbon atoms, and a nitrile group.
Here, R4 to R7 are each independently any one selected from the group consisting of an alkyl group with 1 to 10 carbon atoms, which is substituted with fluorine, and an alkenyl group with 2 to 10 carbon atoms, which is substituted with fluorine.-
