However, the invention can be implemented in various different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, anything not essential to the description of the invention will be omitted for clarity, and similar reference numerals will denote similar elements.

[0045] [Electrode assembly according to the first embodiment of the present invention]

[0046] like Figures 1 to 4 As shown, the electrode assembly 1 according to the first embodiment of the present invention includes a basic unit 10, which includes a C-type dual battery 10A and an A-type dual battery 10B. The C-type dual battery 10A has a structure in which a positive electrode 11, a separator 12, a negative electrode 13, a separator 12, and a positive electrode 11 are stacked in sequence. The A-type dual battery 10B has a structure in which a negative electrode 13, a separator 12, a positive electrode 11, a separator 12, and a negative electrode 13 are stacked in sequence.

[0047] In the basic unit 10 with a stacked structure, C-type dual cells 10A and A-type dual cells 10B can be stacked facing each other, with a separator 20 between the C-type dual cells 10A and the A-type dual cells 10B, thereby creating a structure as follows: Figure 4 Electrode assembly 1 is shown.

[0048] The electrode assembly 1 described above is manufactured using equipment for manufacturing electrode assemblies.

[0049] [Apparatus for manufacturing electrode assemblies according to a first embodiment of the present invention]

[0050] like Figures 5 to 13As shown, the apparatus for manufacturing an electrode assembly according to a first embodiment of the present invention includes a supply device 100 for supplying a separator 20; a plasma generating device 200 for forming an adhesive layer on the surface of the separator 20 supplied by the supply device 100; a setting device 300 for setting a basic unit 10 on the surface of the separator 20 on which the adhesive layer is formed, such that the separator 20 and the basic unit 10 adhere to each other; a laminating device 400 for pressing the separator 20 and the basic unit 10 to bond the separator 20 and the basic unit 10 to each other; and a folding device 500 for folding the separator 20 on which the basic unit 10 is disposed to manufacture an electrode assembly 1 in which the basic units 10 are stacked vertically.

[0051] Supply device

[0052] The supply device 100 is configured to supply the separator sheet. That is, the supply device 100 has a roller structure, and when the supply device 100 rotates, the wound separator sheet 20 is unfolded to be supplied to the folding device 500 via the plasma generation device 200, the setting device 300 and the laminating device 400.

[0053] Plasma generation device

[0054] The plasma generating device 200 is configured to form an adhesive layer on the surface of the separator plate. That is, the plasma generating device 200 forms an adhesive layer on the surface of the separator plate 20 supplied by the supply device (when...). Figure 5 Plasma is generated on the top surface of the separator (when observed in the middle) to form an adhesive layer on the surface of the separator 20.

[0055] Setting device

[0056] The setting device 300 is configured to set the basic unit on the surface of the separator. That is, the setting device 300 holds the basic unit 10 stored at a set position and then sets the basic unit 10 on the surface of the separator (on which the adhesive layer is formed). The basic unit 10 is then adhered to the separator 20 by the adhesive layer.

[0057] Lamination device

[0058] The laminating device 400 is configured to bond the basic unit to the separator. That is, the laminating device 400 is provided as a pair of rolling rollers and presses through the basic unit 10 and the separator 20 of the setting device 300 to bond the basic unit 10 to the separator 20.

[0059] Folding device

[0060] The folding device 500 is configured to manufacture electrode assemblies. That is, the folding device 500 folds the separator 20 (on which the basic unit 10 is disposed) to stack the basic units 10 in the vertical direction. Then, as... Figure 4 As shown, electrode assembly 1 can be manufactured.

[0061] In the apparatus for manufacturing electrode assemblies according to the first embodiment of the present invention, the plasma generation device 200 can be improved to improve the adhesion between the basic unit 10 and the separator 20, the electrolyte impregnation characteristics and the gas emission characteristics, thereby manufacturing high-quality electrode assemblies.

[0062] In other words, in the apparatus for manufacturing an electrode assembly according to the first embodiment of the present invention, a patterned adhesive layer can be formed on the surface of the separator by the plasma generation apparatus 200, such that the basic unit and the separator are patterned and adhered to each other. As a result, adhesion can be improved by the adhesive surface between the basic unit and the separator, and electrolyte impregnation characteristics and gas emission characteristics can be improved by the non-adhesive surface between the basic unit and the separator.

[0063] For example, the plasma generating apparatus 200 is configured to form a patterned adhesive layer on the surface of the separator 20 supplied by the supply device 100, and the plasma generating apparatus 200 includes a roller portion 210 and a plasma generator 220.

[0064] The roller section 210 supports the bottom surface of the separator 20 supplied by the supply device 100, and includes a transfer roller 211 that transfers the separator 20 during rotation and a metal member 212 embedded in the transfer roller 211.

[0065] The plasma generator 220 includes: a body 221, formed to be spaced apart from the conveyor roller 211; a plurality of electrode members 222, which generate plasma only on the surface of the separator 20 that is positioned to face the metal member 212 to form a patterned adhesive layer 21 on the surface of the separator 20; and a guide member 223, which fixes the plurality of electrode members 222 to the body 221.

[0066] The main body 221 is disposed on the separator 20 supported by the conveyor roller 211, and is formed to extend along the width direction of the separator 20, which is perpendicular to the conveying direction of the separator 20. That is, the main body 221 and the conveyor roller 211 have corresponding directions and lengths.

[0067] Here, the main body 221 can be made of non-metallic materials.

[0068] Each electrode component 222 is disposed on the outer surface of the main body 221, corresponding to the conveying direction of the separator, and has the following structure: wherein a plurality of electrode components 222 are arranged at a predetermined interval in the longitudinal direction of the main body 221, corresponding to the width direction of the separator.

[0069] In other words, reference Figure 13 Plasma is generated only on the surface between the multiple electrode members 222 and the metal member 212 where the separator 20 is disposed. Therefore, a patterned adhesive layer 21 can be formed only on the surface between the electrode members 222 and the metal member 212 where the separator 20 is disposed. Of course, since no plasma is generated on the surface of the separator 20 where no electrode members are disposed, a non-adhesive layer 22 is formed. Therefore, the patterned adhesive layer 21 is formed on the surface of the separator 20. As a result, the separator 20 has a pattern in which the patterned adhesive layer 21 and the non-adhesive layer 22 are alternately formed in the width direction. In other words, the patterned adhesive layer 21 is formed on the surface of the separator 20.

[0070] Electrode component 222 can be a corona discharge electrode. Plasma can be stably generated between metal component 212 and body 221 through the corona discharge electrode.

[0071] The guide member 223 is configured to secure multiple electrode members to the body, and when in Figure 6 When observed, it is provided on the top surface of the body 221. The guide groove 223a, formed as an extension in the width direction of the separator 20, is formed on both surfaces corresponding to the conveying direction of the separator 20 (when in...). Figure 6 In each of the surfaces (left and right surfaces when viewed from the center). Multiple electrode components 222 can be mounted in guide grooves 223a to secure the multiple electrode components 222 to the body 221.

[0072] Specifically, the guide member 223 can be detachably coupled to the body 221 to simultaneously secure multiple electrode members to / from the body 221. For example, the guide member 223 can be detachably coupled to the body 221 via a fixing member 225. That is, the fixing member 225 is provided as a fixing bolt that passes through the guide member and is coupled to the body 221. Therefore, when the fixing bolt is tightened, the guide member 223 and the body 221 can be coupled without separating from each other, and when the fixing bolt is loosened, the guide member 223 can be separated from the body. Thus, when the guide member is separated from the body, multiple electrode members can be simultaneously separated from the body, and when the guide member is coupled to the body, multiple electrode members can be simultaneously secured to the body. As a result, the efficiency of maintenance and operation can be improved.

[0073] Here, the guide groove 223a is formed to extend along the width direction of the separator 20. Therefore, each of the plurality of electrode members 222 is slidably and movably coupled to the guide groove 223a of the guide member 223 in the width direction of the separator 20. As a result, the position of each of the plurality of electrode members 222 in the width direction of the separator 20 can be adjusted, and the position of the adhesive layer formed on the separator can also be adjusted.

[0074] The plasma generation apparatus 200 with the above structure generates plasma between the separator 20 and the main body 221 due to the mutual reaction of the metal components disposed in the roller section 210. The roller section 210 is mounted on the guide member 223 of the plasma generator 220 to convey multiple electrode components 222 and separator 20. Here, plasma can be generated only on the surface of the separator 20 disposed between the electrode components 222 and the metal components 212 to form a patterned adhesive layer 21 on the surface of the separator 20.

[0075] Here, multiple electrode components 222 can be slidably moved along the guide groove 223a of the guide member 223 in the width direction of the separator 20, thereby adjusting the position of the patterned adhesive layer 21 to be formed on the separator 20.

[0076] In the separator 20 on which the adhesive layer is formed as described above, the basic unit 10 is disposed on the surface of the separator 20 while passing through the setting device 300. Here, the basic unit 10 is patterned and adhered to both the basic unit 10 and the separator 20 while being adhered to the patterned adhesive layer 21. That is, adhesion can be improved by the adhesive surface between the basic unit 10 and the separator 20, and electrolyte impregnation characteristics and gas emission characteristics can be improved by the non-adhesive surface between the basic unit 10 and the separator 20.

[0077] Therefore, in the apparatus for manufacturing electrode assemblies according to the first embodiment of the present invention, the plasma generation device 200 can be improved to manufacture electrode assemblies having improved electrolyte impregnation characteristics and gas emission characteristics.

[0078] In the plasma generation apparatus 200, the electrode component 222 has a structure that is easy to manufacture and install. Specifically, the electrode component 222 includes: a coupling portion 222a slidably coupled to a guide groove 223a of a guide member 223; an electrode portion 222b that generates plasma simultaneously with the metal member 212 to form a patterned adhesive layer 21 on the surface of the separator 20; and a connecting portion 222c that connects the coupling portion 222a to the electrode portion 222b. In the electrode component 222 with the above structure, only the portion corresponding to the metal member 212 can be formed as the electrode portion 222c, significantly reducing cost. Furthermore, the portion coupled to the guide member 223 can be formed as the coupling portion 222a, which has strength to improve the coupling characteristics with the guide member 223. Additionally, the size and diameter of the connecting portion 222c that connects the coupling portion 222a to the electrode portion 222b can be minimized to minimize weight and cost.

[0079] Specifically, the connecting portion 222c can be detachably coupled to the electrode portion 222b or the coupling portion. That is, the connecting portion 222c can be inserted into the coupling groove formed in the electrode portion 222b or into the recess formed in the coupling portion for coupling. Therefore, when the electrode portion 222b is damaged, maintenance costs can be reduced because only the connecting portion 222c coupled to the coupling portion or the electrode portion 222b coupled to the connecting portion needs to be separated.

[0080] The guide member 223 and the electrode member 222 can have a coupling structure that allows for easy fixing and release. That is, the guide groove 223a includes a portion provided on the outside of the guide member 223 (when in...). Figure 6 When viewed from the center, a first groove 223a-1 (on the left and right surfaces of the guide member) and a second groove 223a-2 provided inside the guide member 223 are shown. The second groove 223a-2 is connected to the first groove 223a-1, and when viewed from the center... Figure 6 When viewed from the center, it has a diameter larger than the first groove 223a-1 in the vertical direction. Moreover, the coupling part 222a includes: a support member 222a-1, which is supported by a guide member 223 and connected to the support member 222a-1 by a connecting part 222c; a coupling bolt 222a-2, which is inserted into the second groove 223a-2 through the first groove 223a-1 by passing through the support member 222a-1; and a coupling nut 222a-3, which is coupled to the coupling bolt 222a-2 provided in the second groove 223a-2.

[0081] Therefore, in the coupling portion 222a, when the coupling bolt 222a-2 and the coupling nut 222a-3 are coupled to each other, the support member 222a-1 can be pressed against the guide member 223 and thus fixed to the guide member 223 without moving, resulting in the position of the electrode portion being fixed. Furthermore, when the coupling between the coupling bolt 222a-2 and the coupling nut 222a-3 is partially or completely released, the fixation of the support member 222a-1 to the guide member 223 can be released, allowing the support member 222a-1 to move within the width direction of the partition plate in the first groove 223a-1, resulting in the electrode portion being able to move within the width of the partition plate. Thereafter, when the coupling bolt 222a-2 and the coupling nut 222a-3 are coupled, the support member 222a-1 can be pressed against the guide member 223 to fix the position of the electrode portion.

[0082] The second groove 223a-2 is formed in the transverse direction of the guide member 223 corresponding to the width direction of the partition 20 (when in Figure 6 When viewed from the center, the guide member passes through the longitudinal direction, allowing the coupling nut 222a-3 to be inserted into the second groove 223a-2. Therefore, the coupling nut 222a-3 can be easily inserted into the second groove 223a-2.

[0083] The main body 221 may also include a support portion 221a that supports the electrode portion 222b. The support portion 221a can support the surface of the electrode portion 222b facing the conveyor roller 211, thus increasing the fixing force. In particular, the support portion 221a is formed to extend in the width direction of the separator and to have a curved surface corresponding to the conveyor roller 211. Therefore, the support portion 221a, which is formed to have a curved surface corresponding to the conveyor roller, can be stably supported, and in particular, the support portion 221a can be stably moved in the width direction of the separator.

[0084] The surface on which the support member 222a-1 can be supported can be on the guide member 223 (when in Figure 6 A display member 224 is provided on the front surface (for observation), and a scale is displayed on the display member 224 in the width direction of the partition 20. Therefore, the movement distance of the support member 222a-1 can be accurately calculated. In particular, the scale is formed symmetrically in the left-right direction with respect to the center line of the equally divided display member 224, so the electrode member can be symmetrically positioned on the left and right sides of the guide member with respect to the center line of the width of the equally divided guide member.

[0085] In the following description of other embodiments of the present invention, the same structural symbols are used for structural symbols having the same configuration as those in the above embodiments, and repeated descriptions will be omitted.

[0086] [Plasma generation apparatus according to a second embodiment of the present invention]

[0087] like Figure 14 and Figure 15 As shown, the plasma generation apparatus 200 according to the second embodiment of the present invention includes a plurality of electrode components 222, each electrode component 222 including a coupling portion, an electrode portion and a connecting portion.

[0088] When viewed in the width direction of the separator 20, the multiple electrode components 222 can be provided as two types with different lengths.

[0089] For example, a plurality of electrode components 222 include a first electrode component 222A disposed at each of the two ends of the main body 221 in the width direction of the separator 20, and a second electrode component 222B provided between the first electrode components 222A. In the width direction of the separator 20, the length of the first electrode component 222A is greater than the length of the second electrode component 222B. Therefore, in the plasma generation apparatus 200 according to the second embodiment of the present invention, as... Figure 15 As shown, adhesive layers of different widths can be formed on the surface of the separator.

[0090] In the plasma generation apparatus 200 according to the second embodiment of the present invention, when viewed in the width direction of the separator 20, only the electrode portions of the first electrode member 222A and the electrode portions of the second electrode member 222B can have different dimensions from each other. Therefore, adhesive layers with different widths can be formed on the surface of the separator 20 by the first electrode member 222A and the second electrode member 222B.

[0091] Accordingly, the scope of the invention is defined more by the appended claims than by the foregoing description and the exemplary embodiments described therein.
