[0003] This invention relates to an activation device and method for activating individual cells of a pouch cell secondary battery during the activation process of a secondary battery. Background Technology

[0004] As fossil fuels gradually deplete, the amount of available fossil fuels is becoming increasingly limited, and the importance of preventing environmental pollution is also increasing. Therefore, the importance of energy sources that can replace fossil fuels is growing. Accordingly, research and development of electricity production technologies based on energy sources with minimal environmental impact (such as solar thermal, hydropower, wind power, ocean energy, and biomass energy) are being actively pursued.

[0005] In particular, the most active research has been conducted on rechargeable secondary batteries that can prevent environmental pollution and provide high energy density. Research and development are underway on the physical, electrical, mechanical, and system aspects of secondary battery materials, efficiency, structure, and processes.

[0006] These secondary batteries are mainly classified into cylindrical, prismatic, and pouch-type batteries based on their shape. Therefore, research and development are underway based on the structural characteristics corresponding to each type of secondary battery with various shapes, in order to improve energy efficiency and energy density or prevent energy inefficiency.

[0007] In terms of energy efficiency and density, secondary batteries have advantages over other types of energy. However, with continuous development in structure, materials, and processes, stability is being studied to ensure even higher efficiency. In particular, various processes are performed during the manufacture of secondary batteries, and therefore, each process requires precise control over the movement, structure, arrangement, and assembly of the battery cells. Therefore, stability is of paramount importance. Summary of the Invention

[0008] Technical issues

[0009] Pouch cells have an electrode assembly housed within a pouch-shaped casing, and high energy density can be ensured in this type of battery by accommodating electrode assemblies in which electrodes and separators are alternately stacked within the casing. However, along with high efficiency, high stability requires the venting of gases generated within the pouch casing during charging and discharging in the cell activation process. Moreover, gas venting demands high precision / airtightness in the manufacturing process of the secondary battery.

[0010] However, during the manufacturing process of secondary batteries, the gas collected in the pouch-shaped casing may not be properly removed, and therefore, during the use of secondary batteries, the energy efficiency or safety may deteriorate due to the increase in internal pressure.

[0011] The present invention, which addresses the aforementioned limitations, aims to provide an activation device and method for secondary batteries that can, as far as possible, discharge gases that may be generated during the manufacturing process of the secondary battery during the charging / discharging phase of the activation process, and can also produce secondary batteries that can be stably manufactured / used.

[0057] The moving member 200 can move along the moving path while picking up the battery cell 100 in a state where the heating pad 212 of the first moving member 210 faces the vacuum pad 221 of the second moving member 220, and thus can simultaneously perform the movement and sealing of the battery cell 100.

[0058] Figures 3a to 3d The state of the moving component and the corresponding state of the battery cell are shown according to an embodiment of the present invention.

[0059] Figure 3a and Figure 3b The diagram shows the state in which the movable component 200 can perform puncture and movement.

[0066] Figure 4 A gas removal method for a single cell of a pouch-type secondary battery according to another embodiment of the present invention is shown. The activation device for a secondary battery according to the present invention can perform the gas removal method for the single cell as will be described later.

[0067] In the activation device according to the invention Figure 4 In the activation method, reference will be made Figure 5 This describes an activation device for performing gas removal on individual cells of a secondary battery.

[0068] In operation 410, the activation device can transfer individual battery cells to the first chamber using the first transfer unit.

[0069] The activation device 500 may include a first chamber 501, a second chamber 502, and a vacuum chamber 503.

[0070] The vacuum level inside the first chamber 501 can be adjusted. The vacuum level inside the first chamber 501 can be adjusted from atmospheric conditions to a vacuum state (e.g., -40 kPa). In the vacuum state, the vacuum level can be defined according to the design. In this invention, -40 kPa is defined as a vacuum state, but this embodiment is not particularly limited.

[0071] Battery cells 100 can be transferred from outside the activation device 500 to the first chamber 501 via the first transfer unit 510. Battery cells 100 outside the activation device 500 can be placed on the first activation tray 511 inside the first chamber 501 via the first transfer unit 510. Multiple battery cells 100 to be activated can be placed on the first activation tray 511.

[0072] The vacuum level inside the first chamber 501 can be adjusted from the outside before, during, and after the transfer of the battery cell 100.

[0073] In operation 420, the activation device can perform puncture of the battery cell by using a moving component.

[0074] In the activation device 500, the movable member 200 can be used to pick up the battery cell 100 placed on the first activation tray 511. In this case, the movable member 200 can be in a state where the puncture needle 211 of the first movable member 210 and the vacuum pad 221 of the second movable member 220 face each other.

[0075] With the puncture needle 211 of the first moving member 210 and the vacuum pad 221 of the second moving member 220 facing each other, puncture can be performed as the puncture needle 211 passes through the degassing portion 160 of the battery cell 100.

[0076] The puncture of a portion of the battery cell 100 can be performed simultaneously with the moving member 200 clamping the battery cell 100.

[0077] In operation 430, the activation device can move the battery cell along the moving line to the vacuum chamber.

[0078] The moving line 520 can be positioned to spatially span the first chamber 501, the second chamber 502, and the vacuum chamber 503. The moving line 520 can support the moving member 200 from the top, enabling the moving member to move.

[0079] The movable component 200 can be connected to the moving line 520. The movable component 200 can be connected to the moving line and move along the moving line 520.

[0080] The movable component 200 can be moved to the vacuum chamber 503 via a first door 512 formed between the first chamber 501 and the vacuum chamber 503 along a moving line 520.

[0081] When the movable component 200 moves into the vacuum chamber 503 via the first door 512, the vacuum level inside the first chamber 501 can be adjusted to a vacuum state (e.g., -40 kPa). Moreover, when the vacuum level of the first chamber 501 becomes a vacuum state (e.g., -40 kPa), the first door 512 can be opened.

[0082] In operation 440, the activation device can perform activation and degassing of the punctured battery cell in a vacuum chamber.

[0083] In the activation device 500, the battery cell 100 can be moved to the vacuum chamber 503 by using the moving member 200, and the battery cell 100 can be placed on the activation unit 530 by using the moving member 200.

[0084] The battery cell 100 placed on the activation unit 530 can be in a punctured state.

[0085] The activation unit 530 may include a compression clamp, and the battery cell 100 may be compressed by the compression clamp. Accordingly, at least the charging / discharging of the activation process can be performed. When the battery cell 100 is compressed, the activation unit 530 can perform pressurization at a high temperature.

[0086] While the battery cell 100 is being compressed by a compression clamp at high temperature, the activation unit 530 can charge / discharge the battery cell 100. Since the battery cell 100 is compressed by the compression clamp during charging / discharging, the gas generated from the battery cell 100 can be collected in the degassing section 160. The sealing portion 150 of the battery cell 100 can be configured such that the generated gas can be collected in the degassing section 160, but this embodiment is not particularly limited.

[0087] The interior of the vacuum chamber 503 can be in a vacuum state (e.g., -40 kPa), and due to the pressure difference, the gas collected in the punctured battery cell 100 is discharged (degassed) to the outside of the battery cell 100. Because the compression clamps compress the battery cell 100, the gas inside the battery cell 100 can be more easily discharged (degassed) to the outside.

[0088] Due to the pressure difference and the pressure of the squeezing clamp, the gas collected inside the battery cell 100 can be easily discharged to the outside.

[0089] In operation 450, the activation device can perform the sealing of the battery cells by using a moving component.

[0090] The battery cell 100, which has been activated and degassed in the activation unit 530, can be held and lifted by the movable member 200.

[0091] When the movable member 200 picks up (or clamps) the battery cell 100, the heating pad 212 of the first movable member 210 and the vacuum pad 221 of the second movable member 220 can be connected while facing each other. The heating pad 212 and the vacuum pad 211 can seal the degassing portion 160 of the battery cell 100 while forming contact with the battery cell 100 and clamping or fixing the battery cell 100.

[0092] In operation 460, the activation device can move the battery cell to the second chamber by using a moving component.

[0093] The movable component 200 can clamp the sealed battery cell 100 and move the battery cell 100 into the second chamber 502 along the moving line 520.

[0094] The movable component 200 can move the battery cell 100 into the second chamber 502 via a second door 542 between the vacuum chamber 503 and the second chamber 502.

[0095] A single battery cell 100 can be placed on a second activation tray 541 inside a second chamber 502 by a moving member 200. Multiple activated battery cells 100 can be placed on the second activation tray 541. Even on the second activation tray 541, the activation device 500 can seal the degassing portion 160 of the battery cell 100 using the heating pad 212 of the first moving member 210 and the vacuum pad 221 of the second moving member 220. Even while the battery cell is being placed on the second activation tray 541 in the second chamber 502, the activation device 500 can seal the degassing portion 160 of the battery cell 100 using the heating pad 212 and the vacuum pad 221.

[0096] The vacuum level inside the second chamber 502 can be adjusted. The vacuum level inside the second chamber 502 can be adjusted from atmospheric pressure to a vacuum state (e.g., -40 kPa). When the moving member 200 moves into the second chamber 502 via the second door 542, the vacuum level inside the second chamber 502 can be adjusted to a vacuum state (e.g., -40 kPa). Furthermore, when the vacuum level of the second chamber 502 becomes a vacuum state (e.g., -40 kPa), the second door 542 can be opened.

[0097] The battery cell 100 placed on the second activation tray 541 can be transferred to the outside of the activation device 500 by the second transfer unit 540 of the second chamber 502. In this case, the vacuum level inside the second chamber 502 can be adjusted to atmospheric conditions. After the vacuum level is adjusted to atmospheric conditions, the battery cell 100 can be transferred to the outside of the activation device 500 by the second transfer unit 540.

[0098] The vacuum level inside the second chamber 502 can be adjusted before, during, and after the transfer of the battery cell 100.

[0099] Although the invention has been described with reference to specific embodiments and drawings, the invention is not limited thereto, and various changes and modifications can be made by those skilled in the art within the scope of the technical concept of the invention and the equivalents of the appended claims.
