Description

Technical Field

[0001] This disclosure relates to an apparatus for manufacturing an electrode assembly and a method for manufacturing an electrode assembly. Background Technology

[0002] While primary batteries are not designed to be (re)charged, secondary (also known as rechargeable) batteries are designed to be discharged and recharged. Among secondary batteries, low-capacity batteries are widely used in portable small electronic devices such as smartphones, feature phones, laptops, digital cameras, and camcorders, while high-capacity batteries are widely used as power sources for motors in hybrid and electric vehicles, as well as for storing electricity (e.g., household and / or utility-scale power storage). A secondary battery typically includes electrode assemblies (including positive and negative electrodes), a housing that houses the electrode assemblies, and electrode terminals connected to the electrode assemblies.

[0003] The electrode assembly may be configured with a separator disposed between the positive and negative electrode plates. The electrode assembly can be manufactured by alternately supplying the positive and negative electrode plates in opposite directions with the separator between them when the separator is stacked in a zigzag shape. In this way, the electrode assembly is manufactured in a Z-stack shape, and the stacked structure including the separator, positive electrode plate, and negative electrode plate may be twisted or collapsed.

[0004] The information disclosed in this Background section is intended to enhance understanding of the background technology of this disclosure. This section may contain information that does not constitute related (or prior art). Summary of the Invention

[0069] Some embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The terms or words used in this specification and claims should not be construed as having a general or dictionary meaning, and should be interpreted as consistent with the technical spirit of this disclosure, based on the principle that the inventor is capable of being his / her own lexicographer to appropriately define the terms and concepts in order to best describe his / her invention. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely some of the embodiments of this disclosure and do not represent all the technical spirit, aspects, and features of this disclosure. Therefore, it should be understood that various equivalents and modifications that can replace or modify the embodiments described herein may exist at the time of filing this application.

[0070] It will be understood that when a component or layer is described as being "on," "connected to," or "attached to" another component or layer, it can be directly on, connected to, or attached to the other component or layer, or one or more intermediate components or layers may be present. When a component or layer is described as being "directly" on, directly connected to, or directly attached to another component or layer, no intermediate components or layers are present. For example, when a first component is described as being "attached" or "connected" to a second component, the first component can be directly attached to or connected to the second component, or the first component can be indirectly attached to or connected to the second component via one or more intermediate components.

[0071] As exemplary views of this disclosure, cross-sectional and / or plan views can be referenced to explain the embodiments described herein. In the drawings, the thickness of films and regions may be enlarged for efficient description of the technical content. Therefore, the regions presented as examples in the drawings have general characteristics, and the shape of the example regions may be used to illustrate specific shapes of device regions. Therefore, this should not be construed as limiting the scope of this disclosure. While terms such as first, second, and third are used to describe various components in the various embodiments herein, the components should not be limited to these terms. These terms are used only to distinguish one component from another. The embodiments described and illustrated herein include supplementary embodiments thereof. Throughout the specification, similar reference numerals indicate similar elements.

[0072] In the accompanying drawings, the dimensions of various elements, layers, etc., may be enlarged for clarity of illustration. The same reference numerals indicate the same elements. As used herein, the term “and / or” includes any and all combinations of one or more associated listed items. Furthermore, the use of “may” in describing embodiments of this disclosure refers to “one or more embodiments of this disclosure.” Expressions such as “at least one of…” and “any one of…” preceding / following the list of elements modify the entire list of elements, but not individual elements in the list. When phrases such as “at least one of A, B, and C,” “at least one of A, B, or C,” “at least one selected from the group of A, B, and C,” or “at least one selected from A, B, and C” are used to specify a list of elements A, B, and C, the phrase may refer to any and all suitable combinations or subsets of A, B, and C, such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the term “use” may be considered synonymous with the term “utilize.” As used herein, the terms “roughly,” “approximately,” and similar terms are used as approximate terms rather than terms of degree and are intended to account for the inherent variations in measurements or calculations that would be apparent to a person skilled in the art.

[0073] It will be understood that while the terms first, second, third, etc., may be used to describe various elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or segment from another element, component, region, layer, or segment. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment.

[0074] For ease of description, this document uses spatial relative terms such as “below,” “under,” “down,” “above,” and “above” to describe the relationship between one element or feature and another element or feature as shown in the figure. It will be understood that spatial relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figure. For example, if the device in the figure is flipped, an element described as “below” or “under” other elements or features can be oriented as “above” or “above” other elements or features. Therefore, the term “below” can encompass both above and below orientations. The device can be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein should be interpreted accordingly.

[0075] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to be limiting of this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will be further understood that when used in this specification, the terms “comprising” and / or “including” specify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0076] Furthermore, any numerical ranges disclosed and / or enumerated herein are intended to include all subranges with the same numerical precision contained within the enumerated ranges. For example, the range “1.0 to 10.0” is intended to include all subranges between the enumerated minimum value of 1.0 and the enumerated maximum value of 10.0 (and including both the enumerated minimum value of 1.0 and the enumerated maximum value of 10.0), i.e., a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as 2.4 to 7.6. Any maximum numerical limit enumerated herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit enumerated in this specification is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to amend this specification, including the claims, to expressly enumerate any subranges contained within the scope expressly enumerated herein. All such ranges are intended to be inherently described in this specification such that any modifications made to expressly enumerate any such subranges will comply with the requirements of local patent law.

[0077] Referring to two compared elements, features, etc., as “identical” may mean that they are “substantially identical.” Therefore, the phrase “substantially identical” can include cases with deviations considered low in the art, such as 5% or less. Furthermore, when a parameter is said to be consistent in a given region, this may mean that it is consistent in terms of its mean.

[0078] Throughout this specification, unless otherwise stated, each element may be singular or plural.

[0079] Placing any element "above (or below)" or "above (or below)" another element may mean that the arbitrary element can be arranged to contact the upper (or lower) surface of the element, and other elements may also be located between the element and any element arranged on (or below) the element.

[0080] Furthermore, it will be understood that when a component is referred to as “connected,” “linked,” or “attached” to another component, the components can be directly “connected,” “linked,” or “attached” to each other, or another component can be “between” the components.

[0081] Throughout this specification, unless otherwise stated, when “A and / or B” is used, it means A, B, or A and B. In other words, “and / or” includes any or all combinations of the listed items. Unless otherwise indicated, when “C to D” is used, it means greater than or equal to C and less than or equal to D.

[0082] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to limit this disclosure.

[0083] Figure 1 An apparatus 100 for manufacturing an electrode assembly is shown according to one or more embodiments of the present disclosure.

[0084] The apparatus 100 for manufacturing electrode assemblies may include a base frame 210, a stacking platform 220, a diaphragm supply device 300, a first electrode supply device 411, and a second electrode supply device 421. The stacking platform 220 is disposed on the base frame 210. The diaphragm supply device 300 is configured to supply a diaphragm 30, including an adhesive layer, to the stacking platform 220 in a zigzag configuration and to reciprocate relative to the base frame in a horizontal direction (e.g., the diaphragm supply device 300 may supply the diaphragm 30, including the adhesive layer, to the stacking platform 220 in a zigzag configuration while reciprocating relative to the ground or the base frame 210 in a horizontal direction). The first electrode supply device 411 is configured to place a first electrode 10 onto the diaphragm 30 while moving in a first direction D1. For example, the first electrode supply device 411 can place the first electrode 10 on the diaphragm 30 that is moved in the first direction D1 by the diaphragm supply device 200, and the second electrode supply device 421 is configured to place the second electrode 20 on the diaphragm 30 while moving in the second direction D2, which is opposite to the first direction D1 (for example, the second electrode supply device 421 can place the second electrode 20 on the diaphragm 30 that is moved in the second direction D2 by the diaphragm supply device 300). In this document, the first direction D1 and the second direction can refer to directions facing opposite sides in the horizontal direction, that is, the first direction D1 can be a direction facing one side in the horizontal direction, and the second direction D2 can be a direction facing the other side in the horizontal direction.

[0085] The stacking platform 220 may be formed of a generally rectangular plate and may be disposed on the base frame 210. A diaphragm 30, a first electrode 10, and a second electrode 20 may be stacked on the stacking platform 220 to form an electrode assembly. The diaphragm 30 is supplied in a zigzag configuration and disposed on the stacking platform 220, and the first electrode 10 and the second electrode 20 are supplied in opposite directions relative to the diaphragm 30, such that the first electrode 10 and the second electrode 20 may be stacked alternately, with the diaphragm 30 disposed between the first electrode 10 and the second electrode 20. The stacking platform 220 may have an area larger than that of the diaphragm 30, such that the diaphragm 30, the first electrode 10, and the second electrode 20 may be stacked in a consistent manner.

[0086] The clamping device 230 can be used to prevent the stacking platform 220 from moving while it is mounted on the base frame 210. In some embodiments, a pair of clamping devices 230 can be used, and the pair of clamping devices 230 can be disposed on both sides of the stacking platform 220. The pair of clamping devices 230 can press the upper sides of both ends of the stacking platform 220 from top to bottom to fix the stacking platform 220 and prevent it from moving. The clamping devices 230 are not limited to this configuration, and any configuration can be applied as long as the clamping devices 230 can fix the stacking platform 220 to prevent it from moving.

[0087] The diaphragm supply device 300 may be disposed above the stacking table 220 and configured to supply the diaphragm 30 to the stacking table 220 in a zigzag configuration while reciprocating in the horizontal direction relative to the ground or base frame 210.

[0088] In some embodiments, the diaphragm supply device 300 may include a supply frame 320, a diaphragm supply roller 310, a support roller 330, a moving frame 340, a roll 350, and a guide roller 360. The supply frame 320 is disposed above the base frame 210. The diaphragm supply roller 310 is disposed (e.g., rotatably disposed) on the supply frame 320 and configured to supply the diaphragm 30 to the supply frame 320. The support roller 330 is disposed (e.g., rotatably disposed) on the supply frame 320 and configured to support the movement of the diaphragm 30. The moving frame 340 (e.g., disposed on the supply frame 320) is configured to reciprocate in a horizontal direction relative to the base frame 210. The roll 350 is disposed (e.g., rotatably disposed) on the moving frame 340 and configured to move the diaphragm 30. The guide roller 360 is disposed (e.g., rotatably disposed) on the moving frame 340 and configured to supply the diaphragm 30 from the roll 350 to the stacking table 220.

[0089] The diaphragm 30 is wound around the diaphragm supply roller 310, and as the roller 350 rotates, the diaphragm 30 wound around the diaphragm supply roller 310 moves, so that the diaphragm 30 can be supplied to the stacking table 220. In some embodiments, a pair of rollers 350 can be provided to pressurize both sides of the diaphragm 30. The rotation of the rollers 350 can be driven by a drive motor.

[0090] The diaphragm supply device 300 may include a conveying control device 370 that adjusts the diaphragm 30 supplied from the diaphragm supply roller 310 to the roll 350 to move without deformation. In some embodiments, the conveying control device 370 may be, but is not limited to, an edge position controller (EPC) sensor or a linear position controller (LPC) sensor.

[0091] The moving frame 340 can be disposed on the supply frame 320 and can be configured to reciprocate in the horizontal direction relative to the base frame 210 to supply the diaphragm 30 supplied by the guide roller 360 in a zigzag configuration to the stacking table 220.

[0092] In some embodiments, the movable frame 340 is configured to slide along the supply frame 320, and the movable frame 340 may be configured to move in a linear reciprocating motion via a drive device. Alternatively, the movable frame 340 may be rotatably coupled to the supply frame 320 and configured to reciprocate within a predetermined angular range via a drive motor. The movable frame 340 is not limited to this configuration, and any configuration may be applied as long as the diaphragm 30 can be supplied to the stacking platform 220 in a zigzag configuration.

[0093] The diaphragm supply device 300 may include a diaphragm stack sensor 380 that senses diaphragms 30 disposed on the supply frame 320 and stacked on the stacking table 220. In some embodiments, a pair of diaphragm stack sensors 380 may be provided, and the pair of diaphragm stack sensors 380 may detect whether the diaphragms 30 are stacked at a set position and size by measuring the ends of the stacked diaphragms 30. The diaphragm stack sensor 380 may be a vision sensor that determines the stacking state of the diaphragms 30 by analyzing captured video images. The diaphragm stack sensor 380 is not limited to this configuration, and any sensor may be used as long as the diaphragm stack sensor 380 can detect the stacking state of the diaphragms 30.

[0094] In some embodiments, the position of the diaphragm 30 stack is detected by the diaphragm stack sensor 380, and when the diaphragm 30 is not in the predetermined set position, the operation of the moving frame 340 can be reset so that the diaphragm 30 is stacked in the predetermined set position.

[0095] The first electrode supply device 411 can be configured to place the first electrode 10 on the diaphragm 30 disposed on the stacking platform 220 in the first direction D1 when the diaphragm supply device 300 moves in the first direction D1 and places the diaphragm 30 on the stacking platform 220. In some embodiments, the first electrode supply device 411 can be configured to deliver the first electrode 10 to be disposed on the diaphragm 30 after drawing the first electrode 10 disposed on the first electrode alignment stage 412 or attaching the first electrode 10 using magnetic force such as an electromagnet. The movement of the first electrode 10 is not limited to this configuration, and various moving devices can be applied.

[0096] The first electrode 10 delivered by the first electrode supply device 411 can be disposed on the first electrode alignment stage 412. Furthermore, the first electrode alignment stage 412 can be equipped with a first electrode alignment sensor 413. In some embodiments, the first electrode alignment sensor 413 can be a visual sensor capable of identifying the arrangement state of the first electrode 10 disposed on the first electrode alignment stage 412. The first electrode alignment sensor 413 is not limited to this configuration, and any sensor can be used, as long as the first electrode alignment sensor 413 can identify the arrangement state of the first electrode 10.

[0097] In some embodiments, the arrangement state of the first electrode 10 disposed on the first electrode alignment stage 412 can be identified by the first electrode alignment sensor 413, and the operation of the first electrode supply device 411 can be adjusted so that the first electrode 10 is attached to a set position of the first electrode supply device 411.

[0098] The second electrode supply device 421 can be configured to place the second electrode 20 on the diaphragm 30 disposed on the stacking stage 220 in the second direction D2 when the diaphragm supply device 300 moves in the second direction D2 and places the diaphragm 30 on the stacking stage 220. In some embodiments, the second electrode supply device 421 can be configured to deliver the second electrode 20 to be disposed on the diaphragm 30 after drawing the second electrode 20 disposed on the second electrode alignment stage 422 or attaching the second electrode 20 using magnetic force such as an electromagnet.

[0110] In this way, the stacking stage 220 is heated to a constant temperature by the high-frequency induction heating device 520, and while the diaphragm 30 is arranged in a zigzag configuration on the stacking stage 220, the first electrode 10 and the second electrode 20 are stacked with the diaphragm 30 disposed between them, and the adhesive layer of the diaphragm 30 is melted by the heat of the stacking stage 220 and adheres to at least one of the first electrode 10 or the second electrode 20, thereby maintaining the stacked state.

Infrared radiation passing through the infrared transmission portion 221 of the stacking platform 220 heats the diaphragm 30, and the adhesive layer of the diaphragm 30 melts and adheres to at least one of the first electrode 10 or the second electrode 20, thereby maintaining the stacked state.

In some embodiments, the heating device may include a first infrared lamp 541 disposed on one side of the movable frame 340 in the horizontal direction and a second infrared lamp 542 disposed on the other side of the movable frame 340 in the horizontal direction.

[0118] In this manner, when the diaphragm 30 is supplied to the stacking stage 220 in a zigzag configuration, the diaphragm 30 is heated by a first infrared lamp 541 and a second infrared lamp 542 disposed on the moving frame 340, causing the adhesive layer of the diaphragm 30 to melt. Since the first electrode 10 and the second electrode 20 are stacked on the diaphragm 30 using the molten adhesive layer, the first electrode 10 and the second electrode 20 can be stacked simultaneously while being adhered to the diaphragm 30.

[0119] In some embodiments, the first infrared lamp 541 can operate to emit infrared radiation toward the diaphragm 30 when the moving frame 340 moves in the first direction D1, and the second infrared lamp 542 can operate to emit light toward the diaphragm 30 when the moving frame 340 moves in the second direction D2.

[0120] Each of the first infrared lamp 541 and the second infrared lamp 542 can operate discontinuously.

[0121] like Figure 6 As shown, when the moving frame 340 moves in the first direction D1, the first infrared lamp 541 operates to emit infrared radiation onto one side of the diaphragm 30, thereby melting the adhesive layer formed on one side of the diaphragm 30. When the first electrode 10 is disposed on one side of the diaphragm 30, one side of the diaphragm 30 and the first electrode 10 can be bonded together.

[0122] like Figure 7 As shown, when the moving frame 340 moves in the second direction D2, the second infrared lamp 542 operates to emit infrared radiation onto the other side of the diaphragm 30, thereby melting the adhesive layer formed on the other side of the diaphragm 30. When the second electrode 20 is disposed on the other side of the diaphragm 30, the other side of the diaphragm 30 and the second electrode 20 can be bonded together.

[0123] The operation of the first infrared lamp 541 and the second infrared lamp 542 is not limited to this configuration, and both the first infrared lamp 541 and the second infrared lamp 542 can operate simultaneously while performing the stacking process.

[0125] The heating device may include an electric heating wire heater 550 disposed on the guide roller 360 to heat the guide roller 360. In some embodiments, the electric heating wire heater 550 may be configured such that a metal material such as copper, formed in the shape of a coil or tube, generates heat when electricity is applied.

[0126] In this way, the guide roller 360 is heated to a certain temperature by the heating wire heater 550, the diaphragm 30 passing through the guide roller 360 is heated, and the adhesive layer of the diaphragm 30 can be melted and disposed on the stacking platform 220. Since the first electrode 10 and the second electrode 20 are stacked on the stacking platform 220 with the diaphragm 30 arranged in a zigzag configuration and disposed between the first electrode 10 and the second electrode 20, the first electrode 10 and the second electrode 20 can be adhered to the diaphragm 30 by the molten adhesive layer.

Furthermore, the stacking platform 220 is maintained at a constant temperature by the heating wire heater 510 disposed on the base frame 210, allowing the adhesive layer of the diaphragm 30 disposed on the stacking platform 220 to melt. Since the first electrode 10 and the second electrode 20 are stacked on the diaphragm 30 using the molten adhesive layer, the first electrode 10 and the second electrode 20 can be stacked simultaneously while being adhered to the diaphragm 30.

[0130] When the heating wire heater 510 is placed on the base frame 210 to heat the stacking platform 220, and the first electrode 10, the diaphragm 30 and the second electrode 20 are stacked at a height greater than a predetermined height, the heat from the stacking platform 220 may not be transferred to the diaphragm 30 stacked on top.

Furthermore, the stacking platform 220 is maintained at a constant temperature by a heating wire heater 510 disposed on the base frame 210, allowing the adhesive layer of the diaphragm 30 disposed on the stacking platform 220 to melt. Since the first electrode 10 and the second electrode 20 are stacked on the diaphragm 30 using the molten adhesive layer, the first electrode 10 and the second electrode 20 can be stacked simultaneously while being adhered to the diaphragm 30.

[0136] Not limited to Figure 10 As shown in the configuration, the high-frequency induction heating device 520 or the infrared lamp 530 can be mounted on the base frame 210.
