Abstract:
An electrolyte in a lithium secondary battery includes an alkyl ammonium salt having a cation of the following Formula 1, a lithium salt, and an organic solvent: wherein R1 to R4 are independently a C1 to C6 alkyl, a C2 to C6 alkenyl, or substituents thereof. The lithium secondary battery has improved cycle life, high rate characteristics, and a high energy density due to an increase of the average discharge voltage at a high rate.
