Description

Technical Field

[0001] This application claims priority to Korean Patent Application No. 10-2022-0179856 filed on December 20, 2022, and Korean Patent Application No. 10-2023-0174881 filed on December 5, 2023 in Korea, the disclosures of which are incorporated herein by reference.

[0002] The present disclosure relates to a carrier for cleaning cylindrical battery cells, cylindrical battery cells manufactured using the same, and battery packs and vehicles including the cylindrical battery cells, and more specifically, to a carrier for cleaning cylindrical battery cells capable of uniformly cleaning cylindrical battery cells, cylindrical battery cells manufactured using the same, and battery packs and vehicles including the cylindrical battery cells. Background Art

[0003] Secondary batteries have high applicability according to product groups and electrical characteristics such as high energy density, and thus are generally applied not only to portable devices but also to electric vehicles (EVs) or hybrid electric vehicles (HEVs) driven by a power source.

[0004] Such secondary batteries are gaining attention as a new energy source that improves eco-friendliness and energy efficiency because they have the major advantage of not only significantly reducing the use of fossil fuels but also generating no byproducts from energy use.

[0005] Currently, widely used secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, etc. The operating voltage of the unit secondary battery cell is about 2.5V to 4.5V.

[0006] Therefore, when a higher output voltage is required, a plurality of battery cells may be connected in series to configure a battery module or a battery pack. In addition, according to the required charge / discharge capacity, a plurality of battery cells may also be connected in parallel to configure a battery module or a battery pack. Therefore, the number and electrical connection type of battery cells included in a battery module or a battery pack may be differently set according to at least one of the required output voltage and the required charge / discharge capacity.

[0007] In addition, cylindrical, prismatic, and pouch-type battery cells are known as types of secondary battery cells. In the case of a cylindrical battery cell, a separator as an insulator is interposed between a positive electrode plate and a negative electrode plate and wound to form a core-wound electrode assembly, which is then inserted into a battery can together with an electrolyte to form a battery. Also, in a cylindrical battery cell, a current collector plate may be used to electrically connect the positive electrode plate and the negative electrode plate, respectively.

[0008] The cylindrical battery cells undergo various processes during the manufacturing process, and in particular, a cleaning process is performed by a cleaning member. Here, the cylindrical battery cells are cleaned by the cleaning member while being placed in a carrier and transferred.

[0009] However, in the related art, when water is sprayed from the cleaning member, the cylindrical battery cells move inside the carrier due to water pressure, and thus there is a problem of uneven cleaning. Summary of the invention

[0046] Hereinafter, the preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The terms used in the specification and the appended claims should not be interpreted as limited to the general meaning and dictionary meaning, but are interpreted based on the meaning and concept corresponding to the technical aspects of the present disclosure on the basis of the principle that allows the inventor to define the terms suitable for the best description.

[0049] Figure 1 is a perspective view of a state before a cylindrical battery cell is placed in a cylindrical battery cell cleaning carrier according to an embodiment of the present disclosure, Figure 2 The cylindrical battery cells are placed in Figure 1 A three-dimensional diagram of the state of the cylindrical battery cell cleaning carrier in the embodiment of the present invention. Figure 3 yes Figure 2 A cross-sectional view of Figure 4 is a perspective view of a state in which a cylindrical battery cell is removed from a cylindrical battery cell cleaning carrier according to an embodiment of the present disclosure, Figure 5 is a plan view of a cylindrical battery cell cleaning carrier according to an embodiment of the present disclosure, Figure 6is a perspective view from the bottom surface of a cylindrical battery cell cleaning carrier according to an embodiment of the present disclosure, and Figure 7 It is along Figure 4 A cross-sectional view taken along line AA' in FIG.

[0050] Reference Figure 1 The cylindrical battery cell cleaning carrier 10 (hereinafter referred to as a cleaning carrier) according to an embodiment of the present disclosure is a carrier in which the cylindrical battery cells 20 are placed during transfer to a cleaning member (not shown) for cleaning the cylindrical battery cells 20.

[0051] The cylindrical battery cell 20 may include an electrode assembly (not shown), a battery can 21 , and a cap plate (not shown).

[0052] The electrode assembly has a structure in which a positive electrode plate, a negative electrode plate, and a separator interposed between the positive electrode plate and the negative electrode plate are wound in one direction. Also, a central hole is formed at the center of the electrode assembly, and the electrode assembly may be formed in a core-wound type.

[0053] For example, the electrode assembly may be manufactured by winding a laminate formed by sequentially stacking a negative electrode plate, a separator, a positive electrode plate, and a separator at least once. Here, the positive electrode plate and the negative electrode plate may be formed in a sheet shape.

[0054] That is, the electrode assembly applied to this embodiment may be a wound type electrode assembly. In this case, an additional separator may be further provided on the outer peripheral surface of the electrode assembly to insulate the battery can 21. That is, the electrode assembly may have a winding structure known in the related art without limitation.

[0055] A positive electrode active material may be applied to one or both sides of the positive electrode plate, and a first uncoated portion to which the positive electrode active material is not applied may be formed at the end of the positive electrode plate. The first uncoated portion is exposed to the outside of the separator while forming a plurality of turns of winding around the center of the electrode assembly, and itself may be used as an electrode tab. However, the first uncoated portion may not be formed on the positive electrode plate.

[0056] A negative electrode active material may be applied to one or both sides of the negative electrode plate, and a second uncoated portion to which the negative electrode active material is not applied may be formed at the end of the negative electrode plate. The second uncoated portion is exposed to the outside of the separator while forming a plurality of turns of winding around the center of the electrode assembly, and itself may be used as an electrode tab. However, the second uncoated portion may not be formed on the negative electrode plate.

[0057] Here, when the positive electrode plate and the negative electrode plate each include an uncoated portion, the first uncoated portion and the second uncoated portion may be configured to face opposite directions.

[0058] Also, the positive electrode active material coated on the positive electrode plate and the negative electrode active material coated on the negative electrode plate may be used without limitation as long as they are active materials known in the art.

[0059] The separator may be a porous polymer film, for example, a porous polymer film made of a polyolefin polymer such as ethylene homopolymer, propylene homopolymer, ethylene / butene copolymer, ethylene / hexene copolymer and ethylene / methacrylate copolymer alone or a stacked structure thereof.

[0060] As another example, the separator may be a conventional porous non-woven fabric, for example, a non-woven fabric made of high melting point glass fiber, polyethylene terephthalate fiber, or the like.

[0061] At least one surface of the diaphragm may include a coating of inorganic particles. In addition, the diaphragm itself may be formed by a coating of inorganic particles. The particles constituting the coating may have a structure coupled with a binder such that there is a gap volume between adjacent particles.

[0062] And, the center hole of the electrode assembly is also used to weld the cell terminal 22 (positive terminal) and the positive current collector plate. That is, it can be configured to weld the cell terminal 22 and the positive current collector plate by irradiating laser through the center hole of the electrode assembly.

[0063] The electrode assembly is accommodated in the battery can 21. And, a through hole may be formed in the battery can 21. Here, the battery can 21 is formed in a cylindrical shape so that the electrode assembly is accommodated inside the battery can 21 and may be electrically connected to the negative electrode plate of the electrode assembly. Therefore, the battery can 21 may have the same polarity as the negative electrode plate (ie, negative electrode).

[0064] The diameter of the battery can 21 is formed to be larger than the diameter of the electrode assembly. A gap of a preset size is formed between the battery can 21 and the positive electrode collector plate, and an insulator may be interposed in the gap.

[0065] If the size of the battery can 21 is set according to the standard and then the size of the electrode assembly is increased, the total capacity of the battery cell increases but the gap between the battery can 21 and the electrode assembly decreases.

[0066] That is, since increasing the size of the electrode assembly to increase the total capacity of the battery cell reduces the gap between the battery can 21 and the electrode assembly, an insulator should be able to be inserted in the reduced gap between the battery can 21 and the electrode assembly to increase the capacity of the battery cell, and to this end, the thickness of the insulator is preferably as thin as possible.

[0067] The battery can 21 is a substantially cylindrical container that may be made of, for example, a conductive material such as metal. The battery can 21 may be made of a conductive metal such as aluminum, steel, stainless steel, etc., but is not limited thereto.

[0068] The positive current collector plate is electrically connected to the positive electrode plate, for example, at the top of the electrode assembly. For example, the positive current collector plate is made of a conductive metal material and can be electrically connected to the first uncoated portion of the positive electrode plate.

[0069] The cell terminal 22 is made of a conductive metal material and is electrically connected to the positive electrode collector plate. Also, the cell terminal 22 is electrically connected to the positive electrode plate of the electrode assembly through the positive electrode collector plate and has a positive polarity.

[0070] That is, the cell terminal 22 may function as a positive electrode terminal. Also, the battery can 21 is electrically connected to the negative electrode plate of the electrode assembly as described above, and has a negative polarity.

[0071] The negative current collector plate is electrically connected to the negative plate, for example, at the bottom of the electrode assembly. For example, the negative current collector plate is made of a conductive metal material such as aluminum, steel, copper, nickel, etc., and can be electrically connected to the second uncoated portion of the negative plate.

[0072] The negative electrode collector plate may be electrically connected to the battery can 21. To this end, the negative electrode collector plate may be fixed with at least a portion of an edge portion thereof interposed between an inner surface of the battery can 21 and the sealing gasket.

[0073] In an embodiment, at least a portion of the edge portion of the negative electrode collector plate may be fixed to the bead portion by welding while being supported on the bottom surface of the bead portion formed at the bottom of the battery can 21 .

[0074] Also, at least a portion of the remaining portion excluding the coupling portion of the edge pressing portion of the negative electrode collector plate may be coupled to the curved surface of the second non-coating portion by welding (eg, laser welding).

[0075] In addition, at least a portion of the edge of the negative electrode current collector plate may be electrically coupled to a surface adjacent to the clamping portion among the upper and lower surfaces of the edge pressing portion.

[0076] The cover plate is configured to seal an opening formed at the bottom of the battery can 21. The cover plate may be made of, for example, a metal material to ensure rigidity.

[0077] Also, the cap plate may be separated from the electrode assembly and may be configured to be non-polar. That is, even if the cap plate is made of a conductive metal material, it may not have polarity.

[0078] The fact that the cap plate has no polarity means that the cap plate is electrically insulated from the battery can 21 and the cell terminals 22. As such, the cap plate does not need to be polarized, and its material does not necessarily have to be a conductive metal.

[0079] The cover plate may be supported by being placed on a pressed edge portion formed on the battery can 21. In addition, the cover plate is fixed by a clamping portion to be described later. A sealing gasket may be interposed between the cover plate and the clamping portion of the battery can 21 to ensure the airtightness of the battery can 21. That is, the sealing gasket may be configured to be interposed between the edge of the cover plate and the opening of the battery can 21.

[0080] The cleaning member (not shown) may be configured in various ways to clean the cylindrical battery cells 20, and may, for example, include a nozzle that sprays water toward the cylindrical battery cells 20. That is, the cleaning member (not shown) may be configured, for example, to spray water toward the cylindrical battery cells 20 that are placed in the cleaning carrier 10 and conveyed.

[0081] Here, when the cylindrical battery cells 20 are moved by water pressure sprayed from a cleaning member (not shown), cleaning may become uneven, but the cylindrical battery cell cleaning carrier 10 according to an embodiment of the present disclosure may solve this problem.

[0082] Reference Figure 1 , a cylindrical battery cell cleaning carrier 10 according to an embodiment of the present disclosure includes a main body portion 100 , a first supporting portion 200 , and a second supporting portion 300 .

[0083] The cylindrical battery cell 20 is housed in the main body portion 100 (see Figure 2 ). The body portion 100 may have various shapes, for example, may be formed in a cylindrical shape, but is not limited thereto.

[0084] Reference Figure 1 and Figure 4 The first support portion 200 protrudes from the main body portion 100 and supports the side surface of the cylindrical battery cell 20, such as Figure 3 as shown in .

[0085] The first support portion 200 may be configured in various shapes, for example, at least one of the first support portions 200 may protrude from a side surface of an inner peripheral portion of the body portion 100. Figure 5 , four first support parts 200 may be provided, and the four first support parts 200 may be formed to be spaced apart from each other at intervals of 90 degrees. However, the number and intervals of the first support parts 200 are not limited thereto.

[0086] And, refer to Figure 1, an inclined portion 210 may be formed on an upper side of the first supporting portion 200 to facilitate seating of the cylindrical battery cell 20. Even if the cylindrical battery cell 20 is slightly deviated from the exact center during a process of being seated in the body portion 100, the lower side of the cylindrical battery cell 20 may contact the inclined portion 210 and slide to be positioned at the exact center.

[0087] The second supporting portion 300 protrudes from the main body portion 100 and supports the bottom surface of the cylindrical battery cell 20. Figure 3 as shown in .

[0088] At least one of the second support parts 300 may protrude from the lower side of the inner peripheral portion of the body part 100. Figure 1 and Figure 6 , the second supporting part 300 may be coupled to a lower end of the first supporting part 200 .

[0089] Reference Figure 5 , four second support parts 300 may be provided, and the four second support parts 300 may be formed to be spaced apart from each other at intervals of 90 degrees. However, the number and intervals of the second support parts 300 are not limited thereto.

[0090] Here, refer to Figure 7 , a rounded portion 310 may be formed in the second supporting portion 300 to facilitate discharge of cleaning water for cleaning the cylindrical battery cells 20. For example, the rounded portion 310 may be formed on an upper surface of the second supporting portion 300. That is, water sprayed from a nozzle of a cleaning member (not shown) may move downward along the rounded portion 310 of the second supporting portion 300.

[0091] As a result, the cylindrical battery cell cleaning carrier 10 according to an embodiment of the present disclosure can not only prevent the cylindrical battery cells 20 from moving during cleaning thereof but also has an effect of facilitating the discharge of water used to clean the cylindrical battery cells 20 .

[0092] Figure 8 is a cross-sectional view of a modified embodiment of a carrier for cleaning a cylindrical battery cell according to an embodiment of the present disclosure.

[0093] Reference Figure 8, the rounded portion 310 may be configured to include a first curved portion 311 and a second curved portion 312. The first curved portion 311 may be formed in a curved shape from a first end of the upper surface of the second support portion 300 toward the center of the upper surface. And, the second curved portion 312 may be formed in a curved shape from a second end of the upper surface opposite to the first end toward the center of the upper surface. And, a straight line portion 320 in the form of a straight line connected to the first curved portion 311 and the second curved portion 312, respectively, may be formed at the center of the upper surface.

[0094] In this way, when the straight portion 320 is formed at the center of the upper surface of the second supporting portion 300, the cylindrical battery cell 20 can be stably placed and supported, and there is also an effect of facilitating the drainage of water used to clean the cylindrical battery cell 20 through the first curved portion 311 and the second curved portion 312 respectively connected to the straight portion 320.

[0095] and Figures 1 to 7 The same content described in can also be applied to Figure 8 implementation method.

[0096] Fig. 9 is a partially cutaway perspective view according to another modified embodiment of a cylindrical battery cell cleaning carrier according to an embodiment of the present disclosure.

[0097] Reference Fig. 9 , the second support portion 300 may include a plurality of unit supports 330a, 330b. Here, the unit support 330 may have a thin plate shape. The plurality of unit supports 330a, 330b are spaced apart from each other, and the drainage portion 340 may be formed in the spaced-apart spaces of the plurality of unit supports 330a, 330b (i.e., the spaces between the plurality of unit supports 330a, 330b). And, the cleaning water for cleaning the cylindrical battery cell 20 may be easily discharged through the drainage portion 340 formed between the plurality of unit supports 330a, 330b.

[0098] and Figures 1 to 7 The content described in or related to Figure 8 The same content described in can also be applied to Fig. 9 For example, the rounded portion 310 may be formed at Fig. 9 Alternatively, the curved portion and the straight portion 320 may be formed together on the upper surface of the unit support member 330. Fig. 9 The upper surface of the unit support 330 may be formed with only straight lines.

[0099] Fig.10 is a cross-sectional view according to still another modified embodiment of the carrier for cleaning a cylindrical battery cell according to an embodiment of the present disclosure.

[0100] Reference Fig.10 , the first support portion 200 may be provided with a gap removing portion 400 to remove a gap between the first support portion 200 and the cylindrical battery cell 20. The gap removing portion 400 may be configured in various ways, and may include, for example, an elastic portion 410 and a contact support portion 420.

[0101] The elastic portion 410 is coupled to the first supporting portion 200. The elastic portion 410 may include various types of configurations having elasticity, and may include, for example, various springs. For example, the elastic portion 410 may be provided as at least one coil spring, but is not limited thereto.

[0102] The contact support portion 420 is coupled to the elastic portion 410 and contacts the side surface of the cylindrical battery cell 20 to support the side surface of the cylindrical battery cell 20. Here, a coating may be formed on the contact support portion 420 to reduce friction when contacting the cylindrical battery cell 20.

[0103] The gap removing portion 400 may remove a gap caused by a processing error or tolerance formed during a manufacturing process of the cleaning carrier 10. That is, since the cylindrical battery cells 20 may collide or interfere with each other during a process of being placed in the cleaning carrier 10, a gap within a preset range may be formed to prevent this.

[0104] However, due to the gap, the cylindrical battery cell 20 may move within the cleaning carrier 10, and in this case, cleaning may become uneven. However, since the gap removing portion 400 is configured to remove the above gap to support the side surface of the cylindrical battery cell 20 while the contact supporting portion 420 contacts the side surface of the cylindrical battery cell 20 by the elastic force of the elastic portion 410, the cylindrical battery cell 20 can be prevented from moving within the cleaning carrier 10, thereby making cleaning uniform.

[0105] and Figures 1 to 9 The same content described in can also be applied to Fig.10 implementation method.

[0106] Fig.11 is a diagram schematically illustrating a configuration of a battery pack including a cylindrical battery cell manufactured using a cylindrical battery cell cleaning carrier according to each embodiment of the present disclosure.

[0107] Reference Fig.11 , the battery pack 30 according to the embodiment of the present disclosure may include one or more cylindrical battery cells 20. Here, the cylindrical battery cell 20 is manufactured using the cylindrical battery cell cleaning carrier 10 according to each embodiment of the present disclosure as described above.

[0108] In addition, the battery pack 30 may further include a battery case 31 for accommodating the cylindrical battery cells 20 , and various devices for controlling charging / discharging of the cylindrical battery cells 20 (such as a BMS, a current sensor, a fuse, etc.).
