Abstract
The present invention relates to an electrolyte for a lithium secondary battery and a lithium secondary battery comprising the same and, more specifically, to an electrolyte for a lithium secondary battery, capable of reducing interfacial resistance of an electrode by comprising an electrolyte additive as an ammonium-based nitrate, and to a lithium secondary battery comprising the same. According to the present invention, a lithium secondary battery can be provided which can suppress the change in average voltage at the time of charging or discharging due to the increase in interfacial resistance of the electrode, and thus has improved charging and discharging efficiency and high-rate characteristics.
