[0001] This request is based on and claims priority from the Request of Korean Patent Number 10-2023-0191778, filed on December 26, 2023, and Korean Patent Application Number 10-20240022072, filed on February 15, 2024, with the Korean Intellectual Property Office, the description of which is incorporated herein by reference in its entirety.

[0002] The present description refers to an electrode production device and a battery cell, which includes an electrode produced using the same, and to a battery pack and a vehicle, which includes the battery cell, and more specifically, to an electrode production device capable of improving electrode quality and a battery cell, which includes an electrode produced using the same, and to a battery pack and a vehicle, which includes the battery cell. BACKGROUND OF THE TECHNIQUE

[0003] In general, a secondary battery refers to a battery that can be repeatedly charged and discharged, such as a lithium-ion battery, a lithium-polymer battery, a nickel-cadmium battery, a nickel-hydrogen battery, a nickel-zinc battery, and the like.

[0004] Depending on the shape of the battery case, a secondary battery can be classified as a cylindrical battery and a prismatic battery, in which the electrode assembly is incorporated into a cylindrical or prismatic metal container, and a bag-type battery, in which the electrode assembly is incorporated into a case of the type Petition 870250073468, dated 08 / 20 / 2025, page 8 / 52 2 / 18 bag made from a sheet of rolled aluminum.

[0005] Such a secondary battery can be manufactured by accommodating an electrode array that includes a positive electrode and a negative electrode that are mutually stacked, with a separator interposed between them, and an electrolyte material in a case of various shapes, and sealing the case.

[0006] The electrode (positive electrode or negative electrode) of the secondary battery may include a coated portion where a coating layer of an active electrode material is formed by pressing an electrode mixture onto the surface of an electrode foil, and an uncoated portion where the coating layer is not formed.

[0007] Meanwhile, the secondary battery electrode can be produced through a roll-to-roll process, in which an electrode sheet that has a coating layer of an active electrode material formed on the surface is manufactured by being wound around a roller and a roll, and moved. And, the electrode can be partially cut to manufacture the electrode assembly and, for example, the electrode can be cut by a laser.

[0008] Here, when cutting the electrode using a laser, foreign matter (e.g., smoke) is generated during the cutting process, and if the foreign matter generated in this way flows into the coated portion (coating layer of the active electrode material), there is a problem of causing a defect in the electrode.

[0050] Referring to Figure 1, an electrode production device 10, according to an embodiment of the present description, refers to a device for producing an electrode (positive electrode or negative electrode) by transferring an electrode sheet 700 onto which a coating layer is formed by an active electrode material. The electrode is a concept that includes both a wet electrode and a dry electrode.

[0051] For example, the wet electrode is manufactured through a process of applying an electrode mixture in a paste state, which includes a solvent, to the surface of an electrode substrate, such as electrode foil 700, to form a coating layer and drying the coating layer.

[0052] And, the dry electrode is manufactured by a process of pressing an electrode mixture in a powder state (powder mixture) that does not include a solvent onto the surface of the electrode sheet 700 to form a coating layer. That is, the electrode mixture is mixed without a liquid medium, such as a solvent or dispersion medium, and then the electrode mixture in a powder state is manufactured by pressing while passing through a rolling mill.

[0053] Here, referring to Figure 7, the electrode sheet 700 may include a coated portion 710 in which a coating layer of an active electrode material is formed on the surface, and a non-coated portion. Petition 870250073468, dated 08 / 20 / 2025, page 16 / 52 10 / 18 coated 720 (e.g., both ends of electrode foil 700) in which the coating layer of an active electrode material is not formed.

[0054] Referring to Figure 5, the electrode production device 10, according to one embodiment of the present description, refers to a device capable of blocking foreign matter 800 generated when irradiating a laser 210 from flowing to a predefined portion of the electrode sheet 700, for example, a coated portion 710 coated with an active electrode material. This will be described in detail below.

[0055] Referring to Figure 1, the electrode production device 10, according to an embodiment of the present description, can be configured to include a transfer member 100, a laser member 200, a gauge member 300 and a foreign matter blocking member 400.

[0056] Transfer member 100 transfers the electrode sheet 700 coated with an active electrode material. The transfer member 100 may be varied and may include, for example, a plurality of rollers for transferring the electrode sheet 700 in a roll-to-roll method. The transfer member 100 is not limited to this, but hereafter, an embodiment in which the transfer member 100 includes a plurality of rollers will be described for convenience of description.

[0057] Referring to Figure 1, the transfer member 100 may include a first transfer roller 110 and a second transfer roller 120. Here, the first transfer roller 110 and the second transfer roller 120 may be arranged in various positions and, for example, as in Figure 1, the first transfer roller 110 may be arranged on the upper side and the second transfer roller 120 may be arranged on the lower side. Petition 870250073468, dated 08 / 20 / 2025, p. 17 / 52 11 / 18

[0058] In this embodiment, the electrode sheet 700 is transferred from the first transfer roller 110 on the upper side to the second transfer roller 120 on the lower side. That is, the electrode sheet 700 moves from the upper side to the lower side by the first transfer roller 110 and the second transfer roller 120.

[0059] Referring to Figure 1, laser member 200 is provided to irradiate laser 210 towards electrode sheet 700. Laser member 200 may include various types of laser equipment. Referring to Figure 1, when electrode sheet 700 is moved from the top side to the bottom side by the first transfer roller 110 and the second transfer roller 120, laser member 200 may be configured to irradiate laser 210 in a horizontal direction, based on Figure 1, towards electrode sheet 700.

[0060] Referring to Figure 1, the jig member 300 is arranged in contact with the electrode sheet 700 to support the electrode sheet 700. The jig member 300 can prevent the electrode sheet 700 from shaking or wobbling when the electrode sheet 700 is cut by the laser member 200, thereby avoiding cutting defects such as irregular cutting or cutting a portion other than a predefined portion when cutting the electrode sheet 700 by the laser member 200.

[0061] The template member 300 can be configured in various ways and may include, for example, a first portion 310, a second portion 320, and a third portion 330. Here, the first portion 310, the second portion 320, and the third portion 330 are merely formal distinctions of the template member 300 for convenience of description, and the criteria for distinguishing the first portion 310, the second portion 320, and the third portion 330 are unclear. For example, the first portion 310, the second portion 320, and the third portion 330 may be manufactured separately and then coupled together to Petition 870250073468, dated 08 / 20 / 2025, page 18 / 52 12 / 18 form the template member 300, but the first portion 310, the second portion 320 and the third portion 330 can also be formed integrally from the manufacturing step.

[0062] Referring to Figure 1, the first portion 310 is arranged in an upward and downward direction. And an internal groove 311 can be formed in the first portion 310. Here, the internal groove 311 can be formed through the first portion 310, the second portion 320, and the third portion 330.

[0063] The second portion 320 is coupled to the first portion 310 on the upper side of the third portion 330 based on Figure 1. And, the third portion 330 is coupled to the first portion 310 on the lower side of the second portion 320, based on Figure 1.

[0064] That is, based on Figure 1, the second portion 320 is arranged on the upper side, and the third portion 330 is arranged on the lower side, and each of these is coupled to the first portion 310. Here, the laser member 200 can irradiate the laser 210 to the part where the gap 340 (see Figure 2) between the second portion 320 and the third portion 330 is located.

[0065] Referring to Figure 5, the foreign matter blocking member 400 is configured to block foreign matter 800 generated when it irradiates the flux laser 210 onto a predefined portion of the electrode sheet 700.

[0066] For example, as described above, when the electrode sheet 700 includes a coated portion 710 coated with an electrode-active material and an uncoated portion 720 not coated with an electrode-active material, the foreign matter blocking member 400 can be configured to be disposed close to the boundary line between the coated portion 710 and the uncoated portion 720 (see Figure 7) to block foreign matter 800 from flowing into the coated portion 710. Petition 870250073468, dated 08 / 20 / 2025, page 19 / 52 13 / 18

[0067] Referring to Figures 3, 6, and 8 together, a second curved portion 410 can be formed in the foreign matter blocking member 400. Referring to Figures 1, 9, and 10, the first curved portions 322 and 332 can be formed in the second portion 320 and the third portion 330 of the template member 300. And the second curved portion 410 of the foreign matter blocking member 400 is formed to correspond to the first curved portions 322 and 332 formed in the second portion 320 and the third portion 330.

[0068] That is, when the first curved portions 322 and 332 are formed in each of the second portion 320 and the third portion 330, if the second curved portion 410 is formed in the foreign matter blocking member 400, there is an interference avoidance effect between the foreign matter blocking member 400 and the second portion 320 and the third portion 330 of the template member 300.

[0069] To this end, the curvature of the second curved portion 410 can be formed to be greater than or equal to the curvature of the first curved portions 322, 332. However, the present description is not limited to this. That is, even if the curvature of the second curved portion 410 is less than that of the first curved portions 322, 332, interference with the gauge member 300 can be avoided by adjusting the position of the foreign matter blocking member 400.

[0070] Here, as shown in Figure 8, a coating portion 420 to prevent foreign matter 800 from adhering can be formed on the second curved portion 410. Based on Figure 8, the coating portion 420 can be formed only on the underside of the foreign matter blocking member 400, or the coating portion 420 can be formed only on the underside of the foreign matter blocking member 400 and on a portion of the side surface of the foreign matter blocking member 400, or the coating portion Petition 870250073468, dated 08 / 20 / 2025, page 20 / 52 14 / 18 timento 420 can be formed in the entire foreign matter blocking member 400.

[0071] And, the foreign matter blocking member 400 can be made of a transparent or translucent material to allow the movement of the foreign matter 800 to be observed, but it is not limited to this. That is, the foreign matter blocking member 400 can be made of an opaque material.

[0072] Referring to Figures 3 and 5, the foreign matter blocking member 400 can be arranged at an inclined angle. The foreign matter blocking member 400 can be damaged by the laser 210 irradiated from the laser member 200, and to avoid such damage to the foreign matter blocking member 400, the foreign matter blocking member 400 can be obliquely arranged at a predefined angle.

[0073] For example, as shown in Figure 5, the foreign matter blocking member 400 can be formed with an inclination that widens outward (to the right based on Figure 5) from the template member 300 towards the laser member 200 and, consequently, there is an effect of preventing damage to the foreign matter blocking member 400 by the laser 210. Furthermore, interference with the progress of the laser 210 by the foreign matter blocking member 400 can be avoided.

[0074] As described above, in the embodiments of the present description, the foreign matter blocking member 400 prevents foreign matter 800 from flowing into, for example, the coated portion 710 of the electrode foil 700 when cutting the electrode foil 700, thereby having the effect of preventing electrode defects and ultimately improving electrode quality.

[0075] Referring to Figures 1 and 2, a suction member 600 is provided to suck up the foreign matter 800. The suction member 600 can Petition 870250073468, dated 08 / 20 / 2025, p. 21 / 52 15 / 18 can be configured in various ways and may include, for example, various suction devices (e.g., vacuum suction devices).

[0076] As in Figure 2, the suction member 600 can be seated in the template member 300 and, for this purpose, as in Figure 4, a seating groove 350 in which the suction member 600 can be seated can be formed in the template member 300.

[0077] Figure 11 is a perspective view of an electrode production device according to a modified embodiment of the present description, Figure 12 is an exploded perspective view of Figure 11 and Figure 13 is a view, seen along the direction of arrow E of Figure 11.

[0078] The modified embodiment of the present description differs in configuration from the first embodiment, in that through holes 321,331 are formed in the jig member 300. In addition, there is a difference in configuration, in that a foreign matter discharge unit 500 is coupled to the jig member 300.

[0079] Here, the content common to the part described in the first embodiment is replaced by the description of the first embodiment described above. Furthermore, the content applicable to the first embodiment between the parts described in the second embodiment may be applied to the first embodiment.

[0080] Referring to Figures 11 and 12 together, the through holes 321, 331 through which foreign matter 800 can pass can be formed in at least one of the second portion 320 and the third portion 330. The through holes 321, 331 can be one large hole, or a plurality of holes can be arranged in various ways.

[0081] And, referring to Figures 11, 12 and 13 together, the foreign matter discharge unit 500 can be coupled to the jig member 300. The foreign matter discharge unit 500 can include a discharge body 510 coupled to the jig member 300 and Petition 870250073468, dated 08 / 20 / 2025, page 22 / 52 16 / 18 a discharge hole 520 formed in the discharge body 510.

[0082] Here, at least one of the second portion 320 and the third portion 330 of the jig member 300 is coupled to the foreign matter discharge unit 500, and the foreign matter 800 passing through the through holes 321,331 formed in at least one of the second portion 320 and the third portion 330 can be discharged through the discharge hole 520 of the foreign matter discharge unit 500. In this case, the through holes 321,331 of the second portion 320 and the third portion 330 and the discharge hole 520 of the foreign matter discharge unit 500 are configured to communicate with each other. And, a suction member (not shown) can be coupled to the discharge hole 520.
