Description

Pouch-type battery cell tray with temperature sensing function

[0001] This application claims the benefit of priority to Korean Patent Application No. 2024-0096173, filed July 22, 2024, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a pouch-type battery cell tray equipped with a temperature sensing function, and more particularly, to a pouch-type battery cell tray equipped with a temperature sensing function capable of measuring the temperature of each pouch-type battery cell stored in the tray.

[0003]

[0004] As technological development and demand for mobile devices increase, rechargeable secondary batteries are increasingly being used as energy sources for a variety of mobile devices. Secondary batteries are also attracting attention as an energy source for electric and hybrid electric vehicles, offering an alternative to conventional gasoline and diesel vehicles that rely on fossil fuels.

[0005] Secondary batteries are classified into cylindrical and prismatic batteries, in which the electrode assembly is built into a cylindrical or prismatic metal can, and pouch-type batteries, in which the electrode assembly is built into a pouch-type case made of aluminum laminate sheet, depending on the shape of the battery case.

[0006] The manufacturing process of a typical pouch-type battery cell includes inserting an electrode assembly into a cell case accommodating space made of a laminate sheet, injecting an electrolyte inside the cell case, sealing it, and performing an activation process.

[0007] During the activation process, there is an aging process. The aging process is a process in which a charged battery is left under specific temperature and charge / discharge conditions for a certain period of time (typically about 7 to 10 days), and then the voltage of the battery is measured, and any batteries below the standard are selected and processed as defective.

[0008] Figure 1 is a perspective view illustrating a battery cell tray according to the prior art. The aging process is performed by storing battery cells in a battery cell tray (1). Of course, the battery cell tray (1) is also used when storing or transporting battery cells.

[0009] Such a battery cell tray (1) may be configured to include a tray body (2) which is a body in which a battery cell is accommodated, a fixing body (3) which is provided inside the tray body (1) and into which a battery cell is inserted and fixed, and a fastening means (4) for fixing and releasing the fixing body (3) to the tray body (1).

[0010] However, since the battery cell tray (1) only has the function of simply storing and fixing the battery cells, it is impossible to determine whether each battery cell is abnormal, for example, whether a defect such as a short circuit has occurred in a specific battery cell, during the aging process or during transport or storage of the battery cells.

[0043]

[0044] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail, so that those skilled in the art can easily implement the present invention. However, when describing the operating principles of preferred embodiments of the present invention in detail, if a detailed description of a related known function or configuration is judged to unnecessarily obscure the gist of the present invention, such detailed description will be omitted.

[0045] Additionally, the same drawing reference numerals are used for parts with similar functions and actions throughout the drawings. Throughout the specification, when a part is said to be connected to another part, this includes not only direct connections but also indirect connections with other elements intervening. Furthermore, inclusion of a component does not exclude other components unless specifically stated otherwise, but rather implies the inclusion of additional components.

[0046]

[0047] Hereinafter, a pouch-type battery cell tray equipped with a temperature sensing function according to the present invention will be described.

[0048] Fig. 2 is a perspective view illustrating a pouch-type battery cell. Referring to Fig. 2, the pouch-type battery cell (10) is configured to include an electrode assembly (not shown) in which a pair of electrode leads (12) are positioned facing each other, a cell case (11) comprising a first pocket portion (11a) for storing the electrode assembly, a second pocket portion (11b) for gas collection, and a sealing portion (11c) at the edges of the first pocket portion (11a) and the second pocket portion (11b).

[0049] Here, the electrode assembly may be formed of, but is not limited to, a jelly-roll type electrode assembly having a structure in which a separator is interposed between long sheet-shaped cathodes and anodes and then rolled up, a stack type electrode assembly having unit cells in which rectangular cathodes and anodes are stacked with a separator interposed between them, a stack-folding type electrode assembly in which the unit cells are rolled up by a long separator film, or a lamination-stack type electrode assembly in which the unit cells are stacked with a separator interposed between them and attached to each other.

[0050] Specifically, the negative electrode is manufactured by applying a slurry containing a negative electrode active material and a binder to a negative electrode current collector.

[0051] Here, as the negative electrode active material, for example, carbon such as non-graphitizable carbon, graphitic carbon; LixFe2O3(0≤x≤1), LixWO2(0≤x≤1), SnxMe1-xMe'yOz(Me: Mn, Fe, Pb, Ge; Me': Al, B, P, Si, elements of group 1, 2, and 3 of the periodic table, halogen; 0 <x≤1; 1≤y≤3; 1≤z≤8) 등의 금속 복합 산화물; 리튬 금속; 리튬 합금; 규소계 합금; 주석계 합금; SnO, SnO2, PbO, PbO2, Pb2O3, Pb3O4, Sb2O3, Sb2O4, Sb2O5, GeO, GeO2, Bi2O3, Bi2O4, Bi2O5 등의 금속 산화물; 폴리아세틸렌 등의 도전성 고분자; Li-Co-Ni계 재료; Si, SiO, SiO2 단독 또는 이들의 혼합물인 Si계 등을 사용할 수 있으나, 이들만으로 한정되는 것은 아니다.

[0052] The positive electrode is manufactured by applying a slurry containing a positive electrode active material and a binder to the positive electrode current collector.

[0053] And as the positive electrode active material, layered compounds such as lithium cobalt oxide (LiCoO2), lithium nickel oxide (LiNiO2), or compounds substituted with one or more transition metals; lithium manganese oxides such as Li1+xMn2-xO4 (wherein, x is 0 to 0.33), LiMnO3, LiMn2O3, LiMnO2; lithium copper oxide (Li2CuO2); vanadium oxides such as LiV3O8, V2O5, Cu2V2O7; Ni-site type lithium nickel oxide expressed by the chemical formula LiNi1-xMxO2 (wherein, M = Co, Mn, Al, Cu, Fe, Mg, B, or Ga, and x = 0.01 to 0.3); Lithium manganese composite oxides represented by the chemical formula LiMn2-xMxO2 (wherein, M = Co, Ni, Fe, Cr, Zn, or Ta, and x = 0.01 to 0.1) or Li2Mn3MO8 (wherein, M = Fe, Co, Ni, Cu, or Zn); LiMn2O4 in which a portion of Li in the chemical formula is replaced with an alkaline earth metal ion; disulfide compounds; Fe2(MoO4)3, etc., but are not limited thereto.

[0054] Meanwhile, the negative current collector and the positive current collector are composed of a portion where a slurry mixed with an active material is applied and a non-coated portion where the slurry is not applied. The non-coated portion is formed by cutting or connecting a separate conductive member to the non-coated portion by ultrasonic welding, etc. to form an electrode tab, and these electrode tabs are gathered to form a tab bundle.

[0055] And a pair of electrode leads (12) consisting of a positive lead and a negative lead are electrically connected to each of the tab bundles of the electrode assembly described above and then exposed to the outside of the cell case (11).

[0056] The cell case (11) uses a laminate sheet composed of an outer covering layer, a metal layer, and an inner covering layer to form a first pocket portion (11a) capable of accommodating an electrode assembly and a second pocket portion (11b) for gas capture.

[0057] Since the inner covering layer is in direct contact with the electrode assembly, it must have insulation and electrolytic resistance, and in order to seal it from the outside, the sealing area where the inner layers are thermally bonded must have excellent thermal bonding strength.

[0058] Materials for such inner covering layers may be selected from, but are not limited to, polyolefin resins such as polypropylene, polyethylene, polyethylene acrylic acid, and polybutylene, which have excellent chemical resistance and good sealing properties, polyurethane resins, and polyimide resins, and polypropylene, which has excellent mechanical properties such as tensile strength, rigidity, surface hardness, and impact strength, and excellent chemical resistance, is most preferable.

[0059] The metal layer in contact with the inner covering layer serves as a barrier layer that prevents moisture or various gases from penetrating into the battery from the outside, and a preferred material for this metal layer is an aluminum film that is lightweight and has excellent formability.

[0060] And the other side of the metal layer is provided with an outer covering layer, and this outer covering layer can use a heat-resistant polymer with excellent tensile strength, moisture permeability, and air permeability to protect the electrode assembly while ensuring heat resistance and chemical resistance, and examples thereof include, but are not limited to, nylon or polyethylene terephthalate.

[0061] In the present invention, the full length direction of the pouch-type battery cell (10) is defined as the z-axis direction (2 o'clock to 8 o'clock direction) based on FIG. 2, and the full width direction is defined as the y-axis direction (12 o'clock to 6 o'clock direction).

[0062]

[0063] FIG. 3 is a conceptual diagram of a pouch-type battery cell tray equipped with a temperature sensing function according to the present invention, FIG. 4 is a cross-sectional view taken along line I-I of FIG. 3, showing a pouch-type battery cell mounted on a mounting portion of the battery cell tray, and FIG. 5 is a cross-sectional view taken along line II-II of FIG. 3, which is a drawing for explaining a temperature sensor portion of a battery cell tray according to the first embodiment of the present invention.

[0064] Referring to FIGS. 2 to 5 together, a pouch-type battery cell tray equipped with a temperature sensing function according to the first embodiment of the present invention is configured to include an external frame (100), a mounting portion (200), and a temperature sensor portion (300).

[0065] First, the external frame (100) forms a first space (S1) to accommodate a plurality of pouch-shaped battery cells (10) having the aforementioned configuration, and may be provided so that a portion of the upper surface and side surfaces are open.

[0066] The outer frame (100) includes a base member (110), a pair of first side members (120), and a pair of second side members (130), and may be provided with an open upper portion.

[0067] In detail, the base member (110) may be provided as a roughly flat plate where the mounting portion (200) is located.

[0068] The first side member (120) may be provided with a side opening (121) formed so that the electrode lead (12) of the pouch-shaped battery cell (10) housed in the first space (S1) is exposed to the outside. In this case, the first side member (120) may be provided as a frame member in which the side opening (121) is formed.

[0069] In addition, the second side member (130) is provided on both sides of a pair of first side members (120) and can be connected to the pair of first side members (120) by being arranged perpendicular to them.

[0070] The mounting portion (200) is continuously placed in the first space portion (S1) formed by the external frame (100) and is configured to include a horizontal member (210) and a plurality of vertical members (220).

[0071] The horizontal member (210) is mounted on the base member (110) in a horizontal direction (3 o'clock to 9 o'clock direction based on FIG. 4), supports the lower portion of the pouch-shaped battery cell (10) in a roughly flat shape, and may be made of an insulating material. At this time, the lower portion of the pouch-shaped battery cell (10) refers to a portion of the first pocket portion (11a) of the pouch-shaped battery cell (10) that is arranged vertically (6 o'clock direction based on FIG. 2).

[0072] The insulating material may include, for example, one or more of polyethylene, polyethylene terephthalate, polypropylene, polystyrene, and polyvinyl chloride, but is not limited thereto as long as it is a material that can maintain insulation while supporting the stored pouch-shaped battery cell (10).

[0073] A plurality of vertical members (220) may be positioned orthogonally to the horizontal member (210) and spaced apart from each other by a certain distance so as to form a third space (S3) in which a pouch-shaped battery cell (10) can be stored vertically. The third space (S3) is a space in which a plurality of vertical members (220) are spaced apart from each other so that a pouch-shaped battery cell (10) can be stored.

[0074] The vertical member (220) may be provided to have a height lower than the full-width height (6 o'clock to 12 o'clock direction based on FIG. 4) of the first pocket portion (11a) of the pouch-shaped battery cell (10) stored in the third space portion (S3). In addition, although not shown in the drawing, the vertical member (220) may be formed with an extension portion (not shown) that supports the first pocket portion (11a) to prevent the pouch-shaped battery cell (10) from being separated from the third space portion (S3). This extension portion may be formed to extend vertically from both ends of the vertical member (220).

[0075] Meanwhile, when multiple pouch-shaped battery cells (10) are stored in the third space (S3), a second space (S2) is formed spaced apart from each other between the battery cells (10).

[0076] The external frame (100) and the mounting portion (200) described above can be implemented in various forms that are obvious to those skilled in the art, so a more detailed description will be omitted.

[0077] Next, the temperature sensor unit (300) may be arranged on the side of the external frame (100) and may be provided to measure the temperature of a plurality of pouch-shaped battery cells (10) housed in the first space (S1). At this time, the side of the external frame (100) on which the temperature sensor unit (300) is arranged may be a first side member (120) or a second side member (130) having a side opening (121) formed therein, and the case where the temperature sensor unit (300) is arranged on the first side member (120) will be described below.

[0078] The temperature sensor unit (300) may be configured to include a moving unit (310), a guide member (320), and a plurality of temperature sensors (330).

[0079] In more detail, the moving part (310) is provided on the first side member (120) and can be provided to be able to move toward the pouch-type battery cell (10). This moving part (310) is configured to include a support member (311), a first moving part (312), and a second moving part (313).

[0080] First, a support member (311) may be provided for the first side member (120). For example, the support member (311) may be provided so as to extend outward from the vertical frame of the first side member (120). In addition, as another example, the support member (311) may be provided so as to be built into the vertical frame of the first side member (120).

[0081] The support member (311) is provided so that the first movable member (312) can be connected to the first side member (120), and an insertion hole (not shown) for connection with the first movable member (312) can be formed in the support member (311).

[0082] The first movable member (312) can be inserted and connected to the support member (311) so as to be able to move in the forward and backward direction (3 o'clock to 9 o'clock direction as of FIG. 5) with respect to the support member (311). For example, the first movable member (312) can be inserted into an insertion hole formed in the support member (311) and moved in the forward and backward direction.

[0083] At this time, the first moving member (312) is preferably provided so that it moves forward and backward with respect to the supporting member (311), but does not come into contact with the electrode lead (12) of the pouch-type battery cell (10) when moving forward.

[0084] In addition, the second movable member (313) is provided on the outer surface of the first movable member (312) and can move left and right (12 o'clock to 6 o'clock direction based on FIG. 5) with respect to the first movable member (312).

[0085] For example, the second movable member (313) may be provided in a form that surrounds the outer surface of the first movable member (312). In addition, as another example, the second movable member (313) may be provided in a form that is coupled to enable left-right sliding movement with respect to the side of the first movable member (312) facing the side opening (121). However, the form of the second movable member (313) is not limited thereto, and may be coupled (arranged) to the first movable member (312) in various forms that enable left-right movement with respect to the first movable member (312).

[0086] The guide member (320) may be provided to extend inward from the moving member (310) toward the pouch-shaped battery cell (10). More specifically, the guide member (320) may be positioned relative to the second moving member (313) and may extend inward toward the pouch-shaped battery cell (10).

[0087] At this time, the guide member (320) is provided in multiple numbers corresponding to the number of second spaces (S2) into which the pouch-type battery cell (10) is inserted, and it is preferable that the guide member (320) is positioned at a certain distance apart so that interference with the pouch-type battery cell (10) does not occur when the pouch-type battery cell (10) is inserted or the guide member (320) is inserted.

[0088] For example, the guide member (320) may be positioned at a certain distance so that it moves toward the pouch-type battery cell (10) when the first moving member (312) moves forward, but is inserted into the second space portion (S2) without interference with the pouch-type battery cell (10). That is, the guide member (320) may be positioned so as to have a distance corresponding to the distance of the pouch-type battery cell (10).

[0089] In addition, the guide member (320) is placed on the second movable member (313), moves together with the second movable member (313) when it moves left and right, and can come into contact with the pouch-type battery cell (10).

[0090] A plurality of temperature sensors (330) can be attached to one or the other surface of the guide member (320) to measure the temperature of the pouch-type battery cell (10). At this time, the plurality of temperature sensors (330) can be provided as contact-type temperature sensors that come into contact with one surface of the pouch-type battery cell (10) to measure the temperature.

[0091] This temperature sensor unit (300) may be provided only for one of the pair of first side members (120) of the outer frame (100), but it may also be provided for each of the pair of first side members (120) to form a pair.

[0092] At this time, a pair of temperature sensor units (300) may be provided to measure the temperature on the same side of the pouch-type battery cell (10). However, this is not limited to this, and a pair of temperature sensor units (300) may be provided to measure the temperature on different sides of the pouch-type battery cell (10).

[0093] Additionally, a pair of temperature sensor units (300) may be provided to measure the respective temperatures near the positive and negative tabs of the pouch-type battery cell (10).

[0094] In addition, the temperature sensor (330) can provide the temperature information of the measured pouch-type battery cell (10) to the control unit (not shown). For example, the temperature information of the pouch-type battery cell (10) measured by the temperature sensor (330) can be transmitted to the control unit via wire or wirelessly, and the control unit can transmit the temperature information of each of the plurality of pouch-type battery cells (10) in real time based on the transmitted temperature information, and can determine whether the pouch-type battery cell (10) is defective by utilizing the deep learning function and transmit a defect signal to the operator.

[0095] For example, if the temperature of one pouch-type battery cell (10) among the received temperature information differs by a certain temperature or more from the temperature of another pouch-type battery cell (10) or has a peculiarity different from the temperature learned in advance, the control unit may determine this to be a defect and display a defect signal on the equipment monitor (e.g., display unit) or transmit it to the operator's terminal (e.g., mobile phone).

[0096] The control unit performs overall control to ensure that each component performs its function properly. This control unit may be implemented in hardware, software, or a combination of hardware and software. The control unit may be implemented in the form of a computing device (operating device) such as a microprocessor, but is not limited thereto. It may be implemented in various forms readily apparent to those skilled in the art.

[0097]

[0098] FIG. 6 is a drawing showing a state in which a temperature sensor part of a pouch-type battery cell tray equipped with a temperature sensing function according to a first embodiment of the present invention approaches a pouch-type battery cell, and FIG. 7 is a drawing showing a state in which a temperature sensor part of a pouch-type battery cell tray equipped with a temperature sensing function according to a first embodiment of the present invention comes into close contact with a pouch-type battery cell.

[0099] For example, a plurality of temperature sensors (330) may be attached to the opposite side (6 o'clock direction as of FIG. 6) of each of a plurality of guide members (320) and moved forward (9 o'clock direction or 3 o'clock direction as of FIG. 6) toward the pouch-type battery cell (10) by a first moving member (312) and moved in the other direction (6 o'clock direction as of FIG. 7) by a second moving member (313). Accordingly, the plurality of temperature sensors (330) may come into contact with one side (12 o'clock direction as of FIG. 7) of the pouch-type battery cell (10) to measure the temperature of the pouch-type battery cell (10).

[0100] In addition, as another example, a plurality of temperature sensors (330) can be attached to one side (12 o'clock direction based on FIG. 6) of each of a plurality of guide members (320), and can move forward toward the pouch-shaped battery cell (10) by the first moving member (312), and move in one direction by the second moving member (313), and come into contact with the other side (6 o'clock direction based on FIG. 7) of the pouch-shaped battery cell (10) to measure the temperature of the pouch-shaped battery cell (10).

[0101] At this time, it is preferable that a plurality of temperature sensors (330) are inserted into the second space (S2) together with the guide member (320) when the first moving member (312) moves forward toward the pouch-shaped battery cell (10).

[0102]

[0103] FIG. 8 is a cross-sectional view taken along line II-II of FIG. 3, and is a drawing for explaining a temperature sensor unit of a battery cell tray according to a second embodiment of the present invention, and FIG. 9 is a drawing showing a temperature sensor unit of a pouch-type battery cell tray equipped with a temperature sensing function according to a second embodiment of the present invention approaching a pouch-type battery cell.

[0104] A pouch-shaped battery cell tray equipped with a temperature sensing function according to a second embodiment of the present invention includes an outer tray (100), a mounting portion (200), and a temperature sensor portion (300), similar to the first embodiment.

[0105] However, unlike the first embodiment, in the second embodiment, the moving part (310) of the temperature sensor part (300) may not include the second moving member (313).

[0106] At this time, the guide member (320) is positioned relative to the first moving member (312), and can approach the pouch-type battery cell (10) only by moving forward without moving left and right, and the plurality of temperature sensors (330) can be provided as non-contact temperature sensors that measure the temperature without making contact with one surface of the pouch-type battery cell (10).

[0107]

[0108] FIG. 10 is a cross-sectional view taken along line II-II of FIG. 3, and is a drawing for explaining a temperature sensor unit of a battery cell tray according to a third embodiment of the present invention, and FIG. 11 is a drawing showing a temperature sensor unit of a pouch-type battery cell tray equipped with a temperature sensing function according to a third embodiment of the present invention approaching a pouch-type battery cell.

[0109] A pouch-type battery cell tray equipped with a temperature sensing function according to a third embodiment of the present invention includes an outer tray (100), a mounting portion (200), and a temperature sensor portion (300), similar to the first and second embodiments.

[0110] However, unlike the second embodiment, in the third embodiment, a temperature sensor (330) may be provided attached to one side and the other side of the guide member (320) so as to measure the temperature of a pair of pouch-shaped battery cells (10) positioned adjacent to each other.

[0111] Accordingly, the number of guide members (320) may not be the same as the number of pouch-type battery cells (10), but may be smaller than the number of third spaces (S3) into which pouch-type battery cells (10) are inserted.

[0112] That is, since a temperature sensor (330) is attached to one side and the other side of one guide member (320), and one guide member (320) guides the pair of pouch-type battery cells (10) so that the temperature of the pair of pouch-type battery cells (10) can be measured, one guide member (320) can be positioned per pair of pouch-type battery cells (10).

[0113] In other words, a plurality of guide members (320) can be arranged to have a spacing distance corresponding to the spacing distance of a pair of pouch-shaped battery cells (10).

[0114] In addition, the plurality of temperature sensors (330) at this time may be provided as non-contact temperature sensors that measure temperature without contacting one surface of the pouch-shaped battery cell (10), similar to the second embodiment.
