Abstract: The present invention relates to a lithium secondary battery having improved high-temperature cycle characteristics and, more specifically, to a lithium secondary battery comprising a positive electrode, a negative electrode, a separator, and an electrolyte, wherein the positive electrode includes lithium iron phosphate as a positive electrode active material, and the electrolyte includes a lithium salt, a first organic solvent, a second organic solvent, and an additive. The first organic solvent is a cyclic lactone compound, the second organic solvent is a carbonate-based organic solvent, and the additive is lithium nitrate (LiNO3). The lithium secondary battery satisfies equation 1. [Equation 1]. In equation 1, A is the total injection amount (g) of the electrolyte injected into the lithium secondary battery, B is the content (wt%) of lithium nitrate (LiNO3) contained in the injected electrolyte, C is the loading amount (g/cm2) of the positive electrode, and D is the total area (cm2) of the surface of a positive electrode current collector.
