| 摘要 |
The present invention relates to an activation method of a secondary battery and, more particularly, to an activation method of a secondary battery comprising a first room-temperature aging step of aging, at room temperature, a secondary battery comprising a cathode including a cathode active material, an anode including an anode active material and a separation membrane and electrolyte inserted between the cathode and the anode; a first charging step of charging the secondary battery aged at room temperature; a high-temperature aging step of aging the primarily charged secondary battery at high temperature; a second aging step of aging, at room temperature, the secondary battery aged at high temperature; a second charging step of charging the secondary battery secondarily aged at room temperature; and a shipping discharging step of discharging the secondarily charged secondary battery. |
