Description

Technical Field

[0001] This application claims the benefit of priority to Korean Patent Application No. 2022-0072082, filed on Jun. 14, 2022, the disclosure of which is incorporated herein by reference in its entirety.

[0002] The present invention relates to a battery cell handling device including a feeding unit configured to enable dispersed feeding and a battery cell feeding method using the battery cell handling device. More specifically, the present invention relates to a battery cell handling device including a feeding unit configured to enable dispersed feeding, which can feed a large number of battery cells into the handling unit in a dispersed state so as to prevent short circuits and explosions caused by contact between the battery cells, and a battery cell feeding method using the battery cell handling device. Background Art

[0003] The use of battery cells is growing exponentially. At the same time, the number of battery cells that need to be disposed of is also growing rapidly. For recycling and environmental reasons, waste batteries must be disposed of professionally.

[0004] Figure 1 is a perspective view of a conventional battery cell handling device 10. Figure 1 , the conventional battery cell disposal apparatus 10 disposes the waste batteries by putting the waste batteries into the disposal unit 200 storing an acid solution, discharging the waste batteries, drying the waste batteries, and crushing the waste batteries.

[0005] When a large number of waste batteries are simultaneously introduced into the disposal unit 200, a short-circuit discharge accident may occur due to contact between the waste batteries. In addition, accidents related to the safety of operators and environmental pollution due to diffusion of the acid solution during introduction must be considered.

[0006] Patent document 1 discloses a waste lithium battery disposal device that disposes of waste lithium batteries by inputting, drilling, cutting and discharging the waste lithium batteries. In Patent document 1, the waste lithium batteries are supplied into a disposal chamber through a battery input unit and a battery supply unit, and a discharge unit provided in the disposal chamber discharges the waste lithium batteries by drilling and cutting the waste lithium batteries, thereby disposing of the waste lithium batteries. In Patent document 1, which is intended to prevent safety-related accidents caused by a wet disposal method using an acidic solution, a non-wet disposal method is used to prevent safety-related accidents. However, in order to dispose of waste lithium batteries, for example, drilling and cutting, an additional disposal device, i.e., a disposal chamber, is required, thereby increasing the equipment manufacturing cost, increasing the maintenance cost due to replacement of operating parts over a period of time, and requiring a larger space for the disposal device.

[0007] Currently, most spent batteries are disposed of using acid solutions, and a simple yet effective solution that can be easily adapted to this environment is needed.

[0035] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those having ordinary skill in the art to which the present invention pertains can easily implement the preferred embodiments of the present invention.

[0036] However, in describing in detail the operating principles of the preferred embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

[0037] In addition, in all drawings, the same reference numerals will be used to represent parts that perform similar functions or operations. Throughout the specification, when a part is described as being connected to another part, not only can the part be directly connected to the other part, but the part can also be indirectly connected to the other part via other parts. In addition, the inclusion of a specific element does not mean the exclusion of other elements, but means that these elements may also be included unless otherwise specified.

[0038] Hereinafter, a battery cell handling device according to the present invention will be described with reference to the accompanying drawings.

[0039] Figure 2 is an exploded perspective view of a battery cell handling device 1000 according to a first embodiment of the present invention, Figure 3 is a cross-sectional view of a battery cell handling device 1000 according to a first embodiment of the present invention.

[0040] For reference, Figure 3 , Figure 5 and Figure 7 The states in which the input units 1100, 2100, and 3100 are not completely coupled to the treatment units 1200, 2200, and 3200 are shown respectively, but the states immediately before the coupling therebetween are shown. When each of the input units 1100, 2100, and 3100 and a corresponding one of the treatment units 1200, 2200, and 3200 are coupled to each other, the upper outer periphery, the inner part, or the lower end of each of the input units 1100, 2100, and 3100 contacts the corresponding one of the treatment units 1200, 2200, and 3200.

[0041] Reference Figure 2 and Figure 3, the battery cell handling device 1000 according to the first embodiment of the present invention includes an input unit 1100 and a handling unit 1200 .

[0042] The input unit 1100 may include a corrosion-resistant material or may be coated with a corrosion-resistant material, and may include an input hole 1110 , an input slope 1120 , a dispersion guide 1130 , and a connection shaft 1140 . The input hole 1110 and the input slope 1120 constitute an input port 1105 .

[0043] The corrosion-resistant material may be at least one material selected from the group consisting of polyolefin resin and glass. Not only the upper surface of the input unit 110 but also the lower portion of the input unit facing the treatment unit 1200 may include the corrosion-resistant material or may be coated with the corrosion-resistant material.

[0044] The curtain C made of a corrosion-resistant resin material extends from or is coupled to the upper outer periphery of the input unit 1100. The curtain C has the advantage of preventing the acid solution in the disposal unit 1200 from splashing to the outside, and even if the acid solution splashes, the acid solution is guided to flow along the curtain C to the ground instead of splashing to a high place, thereby preventing accidents related to the safety of the operator. The curtain C is detachably coupled to the upper outer periphery of the input unit 1100.

[0045] The insertion hole 1110 , which is a hole located at the center of the insertion unit 1100 , can transport a large number of battery cells inserted into the insertion unit 1100 to the handling unit 1200 .

[0046] Each battery cell may be, but is not limited to, a cylindrical battery cell, a square battery cell, or a soft-pack battery cell. The cylindrical battery cell or square battery cell includes: a metal battery cell housing configured to accommodate an electrode assembly, the metal battery cell housing being electrically connected to a negative lead of the electrode assembly; and a top cover located on top of the battery cell housing.

[0047] The top cover is not electrically connected to the battery cell case due to the insulating member, and the top cover is electrically connected to a positive electrode lead and / or a negative electrode lead of the electrode assembly, whereby the top cover serves as a positive electrode terminal.

[0048] In order to fix the battery cell housing and the top cover to each other, the upper surface of the battery cell housing is positioned along the outer periphery of the top cover in a state where the insulating member is interposed between the battery cell housing and the top cover. Preferably, the top cover protrudes more than the upper surface of the battery cell housing, and more preferably, the positive terminal protruding upward is further provided at the center of the top cover.

[0049] The electrode assembly includes a battery cell assembly and a lead, and the battery cell assembly may be: a jelly-roll type battery cell assembly, the jelly-roll type battery cell assembly being configured to have a structure in which a long sheet-shaped positive electrode and a long sheet-shaped negative electrode are wound with a separator interposed therebetween; a stacked type battery cell assembly, the stacked type battery cell assembly including unit battery cells, each of the unit battery cells being configured to have a structure in which a rectangular positive electrode and a rectangular negative electrode are stacked with a separator interposed therebetween; a stacked folding type battery cell assembly, the stacked folding type battery cell assembly being configured to have a structure in which the unit battery cells are wound using a long separator; or a stacked stacked type battery cell assembly, the stacked stacked type battery cell assembly being configured to have a structure in which the unit battery cells are stacked with a separator interposed therebetween and then attached to each other; however, the present invention is not limited thereto.

[0050] In a pair of leads consisting of a positive lead and a negative lead, the positive lead is directly and indirectly connected to the positive lead and the top cover of the battery cell assembly, and the negative lead is electrically connected to the battery cell case. The electrode assembly constituting a cylindrical battery cell is generally known, so a more detailed description thereof will be omitted.

[0051] The battery cell disposal device according to the present invention can also dispose of pouch-type battery cells as needed for disposal after use.

[0052] The conical injection slope 1120 is inclined downward from the edge of the injection unit 1100 toward the injection hole 1110 located at the center of the injection unit 1100 .

[0053] Since the input slope 1120 is formed, when the battery monomers are input, a large number of battery monomers do not stay on the upper surface of the input unit 1100, but move toward the input hole 1110, so that the battery monomers can be quickly and accurately moved to the disposal unit 1200. In addition, the battery monomers on the slope can move slowly along the slope, rather than all moving suddenly at once.

[0054] The surface of the injection slope 1120 may be provided with linear or spiral protrusions or grooves (not shown) extending to the injection hole 1110 to guide the movement of the battery cells.

[0055] The inlet 1105 composed of the inlet hole 1110 and the inlet slope 1120 is generally formed in a truncated cone or a truncated cone shape. Specifically, the upper surface of the inlet can be larger. Figure 2 and Figure 3 A frustum of a cone is shown.

[0056] The dispersion guide 1130 is formed in a cone shape having an apex provided at a central portion of an upper surface thereof, and the dispersion guide 1130 may be located below the input hole 1110 at a distance therefrom.

[0057] As described above, the dispersion guide 1130 can be located below the input hole 1110 to ensure that the battery monomers input for disposal are dispersed throughout the disposal unit 1200, thereby preventing a large number of battery monomers from being input in one direction, for example, the center or edge of the disposal unit 1200, thereby preventing short circuits between the battery monomers.

[0058] The dispersion guide 1130 is preferably made of a soft surface material rather than a hard surface material. A battery cell dropped through the injection hole 1110 may collide with the surface of the dispersion guide 1130, may bounce upward, and may collide with another dropped battery cell. For this reason, preferably, the dispersion guide 1130 is made of a soft surface material. In order to achieve a similar effect, the connecting shaft 1140 may be made of an elastic material.

[0059] The length of connecting shaft 1140 should be at least long enough to allow battery cells dropped through input hole 1110 to be dispersed into the surrounding area after colliding with dispersion guide 1130, and short enough to prevent dispersion guide 1130 from contacting the acid solution in disposal unit 1200.

[0060] The vertex of the dispersion guide 1130 may be located on a vertical extension line of the injection hole 1110 . More preferably, a vertical line of the center of the dispersion guide 1130 and a vertical line of the center of the injection hole 1110 are the same.

[0061] Preferably, the length D3 of the lower surface of the dispersion guide 1130 is equal to or greater than the size D2 of the input hole 1110, in which case the battery cells do not fall directly into the disposal unit 1200 but fall after colliding with the dispersion guide 1130. If the length D3 of the lower surface of the dispersion guide 1130 is smaller than the size D2 of the input hole 1110, the battery cells may fall directly into the disposal unit 1200, whereby the acid solution in the disposal unit 1200 may leak to the outside of the battery cell disposal device, resulting in an accident related to the safety of the operator.

[0062] Specifically, the lower area of ​​the dispersion guide 1130 is equal to or larger than the area of ​​the input hole 1110 , and when the dispersion guide 1130 and the input hole 1110 are horizontally projected, the lower surface of the dispersion guide 1130 must include all sides of the input hole 1110 .

[0063] The surface of the dispersion guide 1130 may be provided with linear or spiral protrusions or grooves (not shown) to guide the movement of the battery cells.

[0064] The dispersion guide 1130 may be further provided with a wing-shaped guide (not shown) extending along an outer circumference thereof, wherein the wing-shaped guide may further prevent scattering of the acidic solution.

[0065] The connection shaft 1140 may be in a rod shape, and may connect an edge of the input hole 1110 and an edge of the dispersion guide 1130 to each other to support and fix the dispersion guide 1130 .

[0066] The position of the dispersion guide 1130 may be set based on the position where the connection shaft 1140 and the dispersion guide 1130 are connected to each other and the length of the connection shaft 1140 .

[0067] At least one connecting shaft 1140 may be provided to connect the input hole 1110 and the dispersion guide 1130 to each other. Preferably, three or four connecting shafts are provided. If less than three connecting shafts 1140 are provided, the supporting force and fixing force between the input hole 1110 and the dispersion guide 1130 may become weak, and if more than four connecting shafts are provided, the moving path of the input battery cell may be disturbed. If two connecting shafts are provided, the dispersion guide 1130 may not be fixed and may rotate when the battery cell is input.

[0068] The disposal unit 1200 may be in a cylindrical shape with an open upper surface, and is used to dispose an acid solution of a battery cell put therein, specifically, a sulfuric acid aqueous solution may be stored in the disposal unit.

[0069] The acid solution in the treatment unit 1200 dissolves or decomposes the outer cover and the casing of each battery cell put into the treatment unit.

[0070] The acidic solution dissolves or corrodes each battery cell put in for disposal, and in the case where thionyl chloride is used as the negative electrode, thionyl chloride reacts with water to become acidic, so continuous re-disposal can be achieved by simply adding water without replenishing sulfuric acid.

[0071] Although not shown in the drawings, a vibrator configured to apply vibration to the entire battery cell handling device may be further added to smoothly insert the battery cell.

[0072] Figure 4 is an exploded perspective view of a battery cell handling device 2000 according to a second embodiment of the present invention, Figure 5 is a cross-sectional view of a battery cell handling device 2000 according to a second embodiment of the present invention.

[0073] Reference Figure 4 and Figure 5 , except for the shape of the dispersion guide 1130, the battery cell handling device according to the second embodiment of the present invention is different from the reference Figure 2 and Figure 3 The battery cell handling device according to the first embodiment described is the same, and thus description of the same structure will be omitted.

[0074] The input unit 2100 of the battery cell handling device 2000 according to the second embodiment of the present invention includes an input hole 2110 , an input slope 2120 , a dispersion guide 2130 , and a connection shaft 2140 .

[0075] The dispersion guide 2130 according to the second embodiment of the present invention is formed in a quadrangular pyramid shape, which has the advantage of being able to intentionally set the direction in which the battery cells are put in so that the battery cells are dispersed more evenly. The quadrangular pyramid is an example, and in addition to the quadrangular pyramid, it can also be transformed into a multi-sided pyramid, such as a triangular pyramid, a pentagonal pyramid, or a hexagonal pyramid.

[0076] The drawings show three connecting shafts 2140, but four connecting shafts may be provided as desired.

[0077] Figure 6 is an exploded perspective view of a battery cell handling device 3000 according to a third embodiment of the present invention, Figure 7 is a cross-sectional view of a battery cell handling device 3000 according to a third embodiment of the present invention.

[0078] Reference Figure 6 and Figure 7 , except for the shapes of the input unit 3100 and the handling unit 3200, the battery cell handling device 3000 according to the third embodiment of the present invention is different from the reference Figure 2 and Figure 3 The battery cell handling device according to the first embodiment described is the same, and thus description of the same structure will be omitted.

[0079] The battery cell handling device 3000 according to the third embodiment of the present invention includes an input unit 3100 and a handling unit 3200 , wherein the input unit 3100 includes an input hole 3110 , an input slope 3120 , a dispersion guide 3130 , and a connection shaft 3140 .

[0080] The input hole 3110 and the input slope 3120 constitute the input port 3105. The input port 3105 is formed in a truncated quadrangular pyramid shape. The input slope 3120 is flat and slopes downward from the edge of the input unit 3100 toward the input hole 3110.

[0081] The dispersion guide 3130 is formed in the shape of a quadrangular pyramid, whereby the direction in which the battery cells are introduced can be intentionally set, and thus the battery cells can be more uniformly dispersed.

[0082] The disposal unit 3200 may be formed in a square cylinder shape with an open upper surface, and an acid solution may be stored in the disposal unit.

[0083] In this way, the advantage of the battery cell handling device according to the third embodiment is that the input port 3105 is formed in a truncated quadrangular pyramid shape, the input slope 3120 is flat, and the handling unit 3200 is formed in a square cylinder shape, so that when multiple battery cell handling devices are installed, the space occupied by the battery cell handling devices can be more effectively utilized.

[0084] The input unit, the dispersion guide, and the treatment unit mentioned in the above embodiments may be combined with each other in any form, and are not limited to the above embodiments.

[0086] Reference Figure 8 In the conventional battery cell handling device 10, when the battery cell is put into the handling unit 200, the acid solution stored in the handling unit 200 may be scattered, thereby causing accidents related to the safety of the operator, such as Figure 8 In addition, after the battery cells are put into the battery, the battery cells are concentrated at one point, which may cause damage, for example, explosion of the battery cells.

[0087] like Figure 8 The advantage of the present invention is that the input unit 1100 including the dispersion guide 1130 is disposed on the upper side of the disposal unit 1200, whereby the battery cells can be stacked in the disposal unit 1200 in a dispersed state, thereby preventing damage, for example, explosion of the battery cells, and the curtain portion C is provided at the input unit 1100 to extend from or be combined therewith, thereby preventing scattering of the acid solution due to the input of the battery cells, thereby preventing accidents related to the safety of the operator.

[0088] In addition, the present invention can provide a battery cell inserting method or a battery cell handling method using the battery cell handling device.

[0089] A battery cell inserting method or a battery cell disposal method using a battery cell disposal device may include the steps of inserting a battery cell through an inserting unit; waiting for the battery cell to be dissolved or decomposed and stabilized; and crushing the dissolved or decomposed battery cell after drying.

[0090] exist Figures 2 to 8In the figure, the insertion port 1105, 2105 or 3105 is shown to be formed in the shape of a truncated cone or a truncated quadrangular pyramid; however, the insertion port can be formed in the shape of a truncated polygonal pyramid, for example, a truncated triangular pyramid or a truncated pentagonal pyramid, as long as the inserted battery cell can move along the insertion slope 1120, 2120 or 3120 toward the insertion hole 1110, 2110 or 3110.

[0091] exist Figures 2 to 8 In the figure, the dispersion guide 1130, 2130 or 3130 is shown as being formed in the shape of a cone or a quadrangular pyramid; however, the dispersion guide can be formed in the shape of a polygonal pyramid, such as a triangular pyramid or a pentagonal pyramid, as long as the input battery cells can be stacked in a dispersed state in the disposal unit 1200, 2200 or 3200.
