Abstract: The present invention relates to an electrolyte composition for a lithium secondary battery. The electrolyte composition for a lithium secondary battery comprises a cyclic ester-based solvent as a main component and a predetermined electrolyte additive, and thus enables the uniform formation of a solid electrolyte interface layer (SEI layer) having high lithium ion conductivity and excellent heat resistance on the surface of an anode when a lithium secondary battery is activated. Consequently, the reactivity between an anode active material and the electrolyte composition is remarkably lowered, resulting in a rise in the temperature at which heat generation begins (that is, an exothermic onset temperature) between the anode active material and the electrolyte composition, thereby suppressing heat generation caused by anode deterioration or the like. Furthermore, a lithium secondary battery comprising the electrolyte composition can minimize side reactions of the electrolyte composition, occurring on the surface of the anode when exposed to high temperatures, thereby exhibiting excellent high-temperature safety.
