Abstract
The present invention provides an electrolyte solution for a lithium secondary battery including an additive, which may prevent a chemical reaction between the electrolyte solution and an electrode by forming a stable solid electrolyte interface (SEI) and a protection layer on the surface of the electrode, and a lithium secondary battery in which life characteristics and high-temperature stability are improved by including the same.
