The present invention relates to an electrolyte for a lithium secondary battery and a lithium secondary battery including the same, and more particularly, to an alkylammonium salt of Formula 1; Lithium salt; And it relates to a lithium secondary battery electrolyte containing an organic solvent and a lithium secondary battery comprising the same.n n n [Formula 1]n n n n n n n n In Chemical Formula 1,n n n R 1 to R 4 are each hydrogen, alkyl having 1 to 6 carbon atoms, alkenyl group having 2 to 6 carbon atoms, or a substituent thereof.n n n The lithium secondary battery containing the electrolyte solution for lithium secondary batteries of the present invention is excellent in life characteristics and high rate characteristics. In particular, at a high rate, the average discharge voltage is increased to increase the energy density. |
