PURPOSE: A method for manufacturing a lithium ion secondary battery is provided to activate a battery by room temperature aging, to increase substantial reversible capacity by pre-charging, and to stabilize a solid electrolyte interface in pre-charging. CONSTITUTION: A method for manufacturing a lithium ion secondary battery comprises: a room temperature aging step(S10) for aging the battery in which electrolyte is injected at a room temperature; a precharging step(S30) for precharging the battery aged at a room temperature; and (S40) a high-temperature aging step for aging the precharged battery at the temperature higher than the room temperature. |
