PURPOSE: Provided are an electrolyte composition excellent in over-charge safety and a lithium secondary battery produced by using the composition, which is excellent in safety for over-charge, cycle property, and bulging property. CONSTITUTION: The electrolyte composition contains a lithium salt, an organic solvent, and 0.1-5wt% of a nitrogen-containing compound and 4-10wt% of cyclohexyl benzene as additives, wherein the nitrogen-containing compound is primary, secondary, or tertiary amine or a polymer, a copolymer, or an oligomer thereof. And the lithium secondary battery is produced by injecting the electrolyte composition into a battery case having an anode, a cathode and a separator, and then sealing. |
