Abstract:
1. A method of fabricating a lithium secondary battery, comprising: interposing a separator between a positive electrode plate and a negative electrode plate, thus manufacturing an electrode assembly; housing the electrode assembly in a battery case, introducing an additive-containing electrolytic solution, and then sealing the battery case; subjecting the sealed battery case to pre-charging, and then removing gas generated by the pre-charging; subjecting the battery case to formation; and removing gas generated by the formation, wherein the additive is one or more selected from the group consisting of LiF the pre-charging is conducted in a range of 10% or less of the lithium secondary battery capacity, wherein the pre-charging is conducted under conditions of current of 0.1˜1 C and voltage of 3.6 to less than 4.4 V.
