[0047] 4 shows a method for removing gas from a battery cell of a pouch-type secondary battery according to another embodiment of the present invention. The secondary battery activation device according to the present invention can perform the method for removing gas from a battery cell as described below. The activation method of the activation device of the present invention shown in FIG. 4 will be described with reference to FIG. 5 which shows an activation device for removing gas from a battery cell of a secondary battery.

[0048] In operation 410, the activation device can transfer the battery cell to a first chamber via a first transporter. The activation apparatus 500 can include a first chamber 501, a second chamber 502, and a vacuum chamber 503.

[0049] The first chamber 501 can adjust the degree of vacuum inside the first chamber 501. The first chamber 501 can adjust the degree of vacuum inside the first chamber 501 from an atmospheric state to a vacuum state (e.g., -40 kpa). The degree of vacuum can be defined according to the design, and in the present invention, -40 kpa is defined as the vacuum state, without any particular limitation.

[0050] The first chamber 501 can transfer the battery cells 100 from outside the activation device 500 to the first chamber 501 via the first transfer unit 510. The first transfer unit 510 can place the battery cells 100 outside the activation device 500 on a first activation tray 511 in the first chamber 501. A plurality of battery cells 100 for activation can be arranged on the first activation tray 511. The first chamber 501 can adjust the degree of vacuum inside before, during, and after the transfer of the battery cell 100 from the outside.

[0051] In operation 420, the activation device can perform drilling on the battery cell via the moving member. The activation device 500 can clamp and lift the battery cells 100 arranged on the first activation tray 511 using the moving member 200. In this case, the moving member 200 may be in a state where the piercing pins 211 of the first moving member 210 and the vacuum pads 221 of the second moving member 220 face each other.

[0052] In a state where the piercing pin 211 of the first moving member 210 and the vacuum pad 221 of the second moving member 220 face each other, the piercing pin 211 penetrates the degassing portion 160 of the battery cell 100 to perform piercing. The perforation of a portion of the battery cell 100 can be performed at the same time that the moving member 200 grips the battery cell 100 .

[0053] In operation 430, the activation device can move the perforated battery cells along a transfer line to a vacuum chamber. The transfer line 520 may be disposed in a form spatially crossing the first chamber 501, the second chamber 502, and the vacuum chamber 503. The transfer line 520 may be supported at an upper portion thereof so that the transfer member 200 can move.

[0054] The moving member 200 can be coupled to a moving line 520. The moving member 200 can be coupled to the moving line and can move along the moving line 520.

[0055] The moving member 200 can be moved along a moving line 520 to the vacuum chamber 503 through a first gate 512 formed between the first chamber 501 and the vacuum chamber 503 .

[0056] When the moving member 200 moves to the vacuum chamber 503 through the first gate 512, the first chamber 501 may adjust the degree of vacuum inside to a vacuum state (e.g., -40 kpa). Alternatively, when the degree of vacuum inside the first chamber 501 becomes a vacuum state (e.g., -40 kpa), the first gate 512 may be opened.

[0057] In operation 440, the activation device can activate and degas the pierced battery cells in a vacuum chamber. The activation device 500 can move the battery cell 100 to the vacuum chamber 503 using the moving member 200 , and can place the battery cell 100 on the activation section 530 using the moving member 200 . The battery cell 100 placed on the activation portion 530 may be in a state in which a hole has been formed.

[0058] The activation unit 530 may include a pressurizing jig, and the battery cell 100 may be pressurized by the pressurizing jig, and at least the charge / discharge of the activation process may be performed accordingly. When pressurizing the battery cell 100, the activation unit 530 may perform the pressurization in a high temperature state.

[0059] The activation unit 530 can perform charging / discharging on the battery cell 100 in a state in which the battery cell 100 is compressed at high temperature via a pressure jig. When charging / discharging, the battery cell 100 is compressed by the pressure jig, so that gas generated in the battery cell 100 can be collected in the degassing unit 160. The seal unit 150 of the battery cell 100 can be formed so that the generated gas can be collected in the degassing unit 160, and is not particularly limited.

[0060] The inside of the vacuum chamber 503 may be in a vacuum state (e.g., -40 kpa), and gas trapped in the perforated battery cell 100 may be discharged (degassed) to the outside of the battery cell 100 due to a pressure difference. The pressurizing jig pressurizes the battery cell 100, so that the gas inside the battery cell 100 may be more easily discharged (degassed) to the outside. This has the effect that the gas trapped inside the battery cell 100 can be easily discharged to the outside due to the pressure difference and the pressure of the pressurizing jig.

[0061] In operation 450, the activation device can seal against the battery cell via the moving member. The battery cell 100 that has been activated and deaerated in the activation unit 530 can be gripped and lifted by the moving member 200.

[0062] When the moving member 200 sandwiches (or holds) the battery cell 100, the heating pad 212 of the first moving member 210 and the vacuum pad 221 of the second moving member 220 may be in a state of being coupled to face each other. The heating pad 212 and the vacuum pad 221 come into contact with the battery cell 100 to hold or fix it, thereby sealing the degassing portion 160 of the battery cell 100.

[0063] In operation 460, the activation device can move the battery cell to the second chamber via the moving member. The moving member 200 can grip the sealed battery cell 100 and move the battery cell 100 along the moving line 520 to the second chamber 502 .

[0064] The moving member 200 can move the battery cell 100 to the second chamber 502 through the second gate 542 between the vacuum chamber 503 and the second chamber 502.

[0065] The moving member 200 can place the battery cells 100 on the second activation tray 541 in the second chamber 502. A plurality of battery cells 100 after activation can be arranged on the second activation tray 541. The activation device 500 can seal the degassing portion 160 of the battery cells 100 on the second activation tray 541 as well, using the heating pad 212 of the first moving member 210 and the vacuum pad 221 of the second moving member 220. The activation device 500 can seal the degassing portion 160 of the battery cells 100 by using the heating pad 212 and the vacuum pad 221 while placing the battery cells 100 on the second activation tray 541 in the second chamber 502.

[0066] The second chamber 502 may adjust the degree of vacuum inside the second chamber 502. The second chamber 502 may adjust the degree of vacuum inside from an atmospheric state to a vacuum state (e.g., -40 kpa). When the moving member 200 moves to the second chamber 502 through the second gate 542, the second chamber 502 may adjust the degree of vacuum inside to a vacuum state (e.g., -40 kpa). Alternatively, when the degree of vacuum inside the second chamber 502 becomes a vacuum state (e.g., -40 kpa), the second gate 542 may be opened.

[0067] The second chamber 502 can transfer the battery cells 100 arranged on the second activation tray 541 to the outside of the activation device 500 via the second transfer unit 540. In this case, the second chamber 502 can adjust the degree of vacuum inside to an atmospheric state, and can transfer the battery cells 100 to the outside of the activation device 500 via the second transfer unit 540 after the degree of vacuum is adjusted to an atmospheric state. The second chamber 502 can adjust the degree of vacuum inside before, during, and after the transfer of the battery cell 100 .
