Abstract
The present invention relates to a method for manufacturing a lithium secondary battery, the method comprising: a step of preparing an electrode assembly comprising a positive electrode, a negative electrode, and a separator; a step of accommodating the electrode assembly in a battery case; a step of injecting a first non-aqueous electrolyte into the battery case to manufacture a pre-lithium secondary battery; a step of activating the pre-lithium secondary battery; and a step of injecting a second non-aqueous electrolyte into the activated pre-lithium secondary battery, wherein the first non-aqueous electrolyte comprises a first organic solvent comprising a linear carbonate-based solvent, and the second non-aqueous electrolyte comprises a second organic solvent comprising an ester-based solvent.
