    摘要： An activation apparatus for a secondary battery according to the present invention includes: a first chamber which includes a first conveyance unit for conveying a battery cell and adjusts a vacuum level in a space in which the first conveyance unit is positioned; a vacuum chamber which is spatially connected to the first chamber, includes an activation unit in which the battery cell is disposed so that activation and degassing of the battery cell are performed, and maintains a vacuum state in a space in which the activation unit is disposed; a second chamber which is spatially connected to the vacuum chamber, includes a second conveyance unit for conveying the battery cell, and adjusts a vacuum level in a space in which the second conveyance unit is positioned; a movement line disposed to cross the first chamber, the vacuum chamber, and the second chamber; and a movement member which is connected to the movement line and moves the battery cell along the movement line, wherein piercing of the battery cell is performed in the first chamber, the activation and degassing of the battery cell are performed in the activation unit, and sealing of the battery cell is performed in the vacuum chamber or the second chamber.
    An activation apparatus for a secondary battery and an activation method therefor according to the present invention may provide high stability as gases, which may be generated/collected in a pouch during charging/discharging, are efficiently removed in an activation process of a battery cell of the secondary battery. Also, processes may be simplified, and the size of the battery cell may be reduced.

    摘要： The present invention relates to a method for manufacturing a secondary battery. The method for manufacturing the secondary battery comprises: an electrode preparation step (S10) of preparing electrodes, each of which is provided with a coating portion coated with an electrode active material and a non-coating portion that is not coated with the electrode active material; an electrode assembly manufacturing step (S20) of alternately stacking the electrodes and separators to manufacture an electrode assembly, wherein the electrodes are stacked so that the non-coating portions overlap each other; a non-coating portion bonding step (S30) of bonding the overlapping non-coating portions to each other; a display part formation step (S40) of forming a display part for setting a cutting point on a surface of the bonded non-coating portion; and an electrode tab manufacturing step (S50) of cutting the bonded non-coating portion with respect to the display part to manufacture an electrode tab.
