Description

Technical Field

[0001] Embodiments of the present invention relate to an all-solid-state battery fixing device and an all-solid-state battery delivery system including the device. Background Technology

[0002] The performance improvement of lithium-ion batteries has reached its limit. Recently, all-solid-state batteries, which use solid electrolytes instead of liquid electrolytes, have attracted much attention.

[0003] Compared to secondary batteries that typically use liquid electrolytes, all-solid-state batteries do not experience electrolyte decomposition due to overcharging. They also have higher cycle durability and energy density. Because the electrolyte is solid, they are not only less susceptible to temperature changes and external shocks, making them safer, but they also have a higher energy density than lithium-ion batteries.

[0004] On the other hand, it is known that in all-solid-state batteries, the contact resistance between active material particles responsible for the battery reaction, or between active material particles and solid electrolyte particles, has a significant impact on the battery's internal resistance. Currently, techniques have been proposed to suppress the increase in internal resistance by improving the properties of the contact between these active material particles or between active material particles and solid electrolyte particles.

[0005] As a method for manufacturing all-solid-state batteries to improve the contact properties between these particles, a method has been proposed to make the particles in close contact with each other to minimize the gap between the particles, and a method to manufacture all-solid-state batteries by pressurizing the all-solid-state battery. The above background technology is technical information that the inventors acquired in order to derive the present invention, or obtained in the process of deriving the present invention, and should not necessarily be regarded as publicly known technology that was disclosed to the public before the present invention application.

When describing the invention with reference to the drawings, the same or corresponding components are referred to by the same reference numerals, and repeated descriptions thereof are omitted.

[0040] Figure 1 This is a perspective view of an all-solid-state battery delivery system 1 according to an embodiment of the present invention. Figure 2 for Figure 1 The side view of the all-solid-state battery delivery system 1 shown.

[0041] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, the all-solid-state battery delivery system 1 heats and pressurizes the all-solid-state battery SB while delivering it along a preset path, and the all-solid-state battery delivery system 1 may include a first delivery device 100, a second delivery device 200, a heating unit 300, a pressurizing unit 400, an all-solid-state battery fixing device 500, and a supply unit 600.

[0042] The all-solid-state battery SB introduced into the all-solid-state battery delivery system 1 can move along a preset path, and a heating process and / or a pressurization process can be performed during the movement of the all-solid-state battery SB along the preset path.

[0043] All-solid-state batteries (SB) can be formed by sequentially stacking a positive electrode layer, a solid electrolyte layer, and a negative electrode layer.

[0044] In one embodiment, the all-solid-state battery SB can be a single cell, but is not limited thereto, and the all-solid-state battery SB can include bi-cell and stacked cells.

[0045] In this specification, a single cell can be understood as a single cell consisting of a single positive electrode layer, a single negative electrode layer, and a single solid electrolyte layer, while a stacked cell can be understood as a cell (cell) formed by stacking and connecting multiple single cells.

[0046] In an alternative embodiment, the stacked cells can be bipolar cells.

[0047] The positive electrode layer can be lithium oxide. Specifically, the positive electrode layer can be formed from layered compounds (such as lithium cobalt oxide (LiCoO2), lithium nickel oxide (LiNiO2), etc.), or compounds substituted with one or more transition metals, lithium manganese oxide (such as LiMnO3, LiMn2O3, etc.), lithium copper oxide, vanadium oxide (such as LiV3O8, LiFe3O4, V2O5, Cu2V2O7, etc.), Ni-site type lithium nickel oxide, lithium manganese composite oxide, or a combination thereof, but not limited thereto, and the positive electrode layer can be formed from various types of positive electrode materials that can be used as the positive electrode of a battery within the scope of the technical concept.

[0048] The negative electrode layer can be formed from carbon (such as non-graphitizable carbon, graphitized carbon (natural graphite, artificial graphite), etc.), metal composite oxides (such as Li x Fe2O3 (0 ≤ x ≤ 1), Li x WO2 (0 ≤ x ≤ 1), Sn x Me 1-x Me’ y O z (Me: Mn, Fe, Pb, Ge; Me: Al, B, P, Si, elements of Group 1, Group 2, Group 3 of the periodic table, halogens; 0 < x ≤ 1; 1 ≤ y ≤ 3; 1 ≤ z ≤ 8), etc.), lithium metal, lithium alloy, silicon-based alloy, tin-based alloy, metal oxides (such as SnO, SnO2, PbO, PbO2, Sb2O3, GeO, GeO2, Bi2O3, Bi2O4, etc.), conductive polymers such as polyacetylene, Li-Co-Ni-based materials, titanium oxide, lithium titanium oxide, or a combination thereof, but not limited thereto, and the negative electrode layer can be formed from various types of negative electrode materials that can be used as the negative electrode of a battery within the scope of the technical concept.

[0049] The solid electrolyte layer can include at least one or more of sulfide-based materials (such as LGPS (Li 10 GeP2S 12 ), LSPSCl (Li 9.54 Si 1.74 P 1.44 S 11.7 Cl 0.3 ), and argyrodite, etc.), oxide-based materials (such as perovskite (Perovskite, LLTO), garnet (Garnet, LLZO), sodium superionic conductor (NASICON), and lithium superionic conductor (LISICON), etc.), or polymer-based materials (such as PEO, etc.), but not limited thereto.

[0050] Refer to Figure 1and Figure 2 The first conveying device 100 conveys the first conveying plate 510 described below, and a plurality of first conveying plates 510 may be connected to the first conveying device 100.

[0051] Specifically, the first conveying device 100 can be configured as a continuous loop structure that circulates along a closed loop path, and a plurality of first conveying plates 510 can be arranged sequentially along the closed loop path.

[0052] The second conveying device 200 conveys the second conveying plate 520 described below, and a plurality of second conveying plates 520 may be connected to the second conveying device 200.

[0053] Specifically, the second conveying device 200 can be configured as a continuous loop structure that circulates along a closed loop path, and a plurality of second conveying plates 520 can be arranged sequentially along the closed loop path.

[0054] The first conveying device 100 and the second conveying device 200 can be arranged at intervals from each other, and the all-solid-state battery SB can pass between the first conveying device 100 and the second conveying device 200.

[0055] For example, the all-solid-state battery SB can be located between a first conveying plate 510 connected to the first conveying device 100 and a second conveying plate 520 connected to the second conveying device 200, and can be conveyed along the circulation path of the first conveying device 100 and / or the second conveying device 200.

[0056] The first conveying device 100 and the second conveying device 200 can be arranged side by side in one direction.

[0057] The term "one direction" can be interpreted as the direction in which the positive electrode layer, solid electrolyte layer, and negative electrode layer of the all-solid-state battery (SB) are stacked.

[0058] Reference Figure 1 and Figure 2 According to one embodiment of the present invention, the heating part 300 is a component for heating an all-solid-state battery SB, and may be located inside the first conveying device 100 and / or the second conveying device 200.

[0059] Specifically, the heating unit 300 can heat the all-solid-state battery SB that is conveyed along with the first conveying device 100 and / or the second conveying device 200, thereby achieving effects such as improving the interfacial bonding of the all-solid-state battery SB, densifying the solid electrolyte, chemically stabilizing the electrode / electrolyte interface, and forming and stabilizing the crystal structure.

[0060] There may be a plurality of heating units 300, and the plurality of heating units 300 may be located inside the first conveying device 100 and the second conveying device 200, respectively.

[0061] For example, the heating unit 300 located inside the first conveying device 100 can apply heat to the first conveying plate 510 that is in contact with one surface of the all-solid-state battery SB, and the heating unit 300 located inside the second conveying device 200 can apply heat to the second conveying plate 520 that is in contact with the other surface of the all-solid-state battery SB.

[0062] The first conveying plate 510 and the second conveying plate 520 can make surface contact with the outer peripheral surface of the all-solid-state battery SB. The heating unit 300 does not directly heat the all-solid-state battery SB, but indirectly heats it through the first conveying plate 510 and the second conveying plate 520 that make large-area surface contact with the all-solid-state battery SB, thereby achieving the effect of uniformly applying the heat emitted by the heating unit 300 to the all-solid-state battery SB.

[0063] Reference Figure 1 and Figure 2 According to one embodiment of the present invention, the pressurizing part 400 is a component for pressurizing the all-solid-state battery SB, and may be located inside the first conveying device 100 and / or the second conveying device 200.

[0064] Specifically, the pressurizing unit 400 can pressurize the all-solid-state battery SB that is conveyed along with the first conveying device 100 and / or the second conveying device 200, thereby achieving effects such as enhancing the interfacial contact tightness of the all-solid-state battery SB, densifying the solid electrolyte, and ensuring mechanical stability.

[0065] There may be a plurality of pressurizing units 400, and the plurality of pressurizing units 400 may be located inside the first conveying device 100 and the second conveying device 200, respectively.

[0066] For example, the pressurizing part 400 located inside the first conveying device 100 can apply pressure to the first conveying plate 510 that is in contact with one surface of the all-solid-state battery SB, and the pressurizing part 400 located inside the second conveying device 200 can apply pressure to the second conveying plate 520 that is in contact with the other surface of the all-solid-state battery SB.

[0067] In other words, the pressurizing part 400 does not directly contact the all-solid-state battery (SB), but applies pressure to the first conveying plate 510 and the second conveying plate 520 that have large-area surface contact with the all-solid-state battery SB to compress the all-solid-state battery SB. This allows for the application of uniform compressive force to the all-solid-state battery SB while effectively protecting its durability.

[0068] In one embodiment, the pressurizing unit 400 may include a heater. Therefore, the all-solid-state battery SB can be heated simultaneously with the pressurizing unit 400, thereby effectively compressing and fixing the all-solid-state battery SB.

[0069] Figure 3 This is a perspective view of an all-solid-state battery fixing device 500 according to an embodiment of the present invention. Figure 4 for Figure 3 An exploded perspective view of the all-solid-state battery mounting device 500 shown.

[0070] Reference Figure 3 and Figure 4 According to an embodiment of the present invention, an all-solid-state battery fixing device 500 covers the outer peripheral surface of an all-solid-state battery SB, and the all-solid-state battery fixing device 500 may include a first conveying plate 510, a second conveying plate 520, a first fixing part 530 and a second fixing part 540.

[0071] The all-solid-state battery mounting device 500 can be fastened to the all-solid-state battery delivery system 1. Specifically, the all-solid-state battery mounting device 500 can be detachably fastened to the all-solid-state battery delivery system 1.

[0072] Therefore, when a portion of the all-solid-state battery fixing device 500 is damaged due to the operation of the heating unit 300 or the pressurizing unit 400, it is easy to replace only the damaged all-solid-state battery fixing device 500 in the first conveying device 100 and the second conveying device 200.

[0073] Specifically, a plurality of first conveying plates 510 are detachably fastened to the first conveying device 100, and a plurality of second conveying plates 520 are detachably fastened to the second conveying device 200. When any one of the plurality of first conveying plates 510 and second conveying plates 520 is damaged, it is very convenient to simply remove the damaged first conveying plate 510 or second conveying plate 520 from the first conveying device 100 or the second conveying device 200 for replacement.

[0074] Reference Figure 1 , Figure 3 and Figure 4 The first conveying plate 510 is connected to the first conveying device 100 and can move along the circulation path of the first conveying device 100.

[0075] The first conveying plate 510 can make surface contact with one surface of the all-solid-state battery SB, thereby covering the surface.

[0076] Specifically, the first delivery plate 510 may cover one surface of the all-solid-state battery SB mounted on the second delivery plate 520.

[0077] The first conveying plate 510 can be formed as a flat plate, and the thickness of the first conveying plate 510 can be relatively thinner than the thickness of the all-solid-state battery SB.

[0078] For example, the thickness of the first conveying plate 510 can be 1 mm or less, 0.5 mm or less, or 0.2 mm or less.

[0079] Therefore, the first conveying plate 510 is formed to be relatively thin compared to the all-solid-state battery SB, so that the first conveying plate 510 can effectively protect the outer peripheral surface of the all-solid-state battery SB, and at the same time effectively transfer heat or pressure from the outside to the outer peripheral surface of the all-solid-state battery SB.

[0080] The second conveying plate 520 is connected to the second conveying device 200 and can move along the circulation path of the second conveying device 200.

[0081] The second conveying plate 520 can make surface contact with another surface of the all-solid-state battery SB, thereby covering the other surface. Specifically, the second conveying plate 520 can cover the other surface of the all-solid-state battery SB by making surface contact with the other surface of the all-solid-state battery SB, which is opposite to a surface on the all-solid-state battery SB that is in surface contact with the first conveying plate 510.

[0082] Refer again Figure 1 and Figure 2 The all-solid-state battery SB supplied by the supply department 600 can be mounted on the second delivery plate 520.

[0083] The all-solid-state battery SB, which is placed on the second conveying plate 520, can be conveyed along the circulation path of the second conveying device 200. The all-solid-state battery SB conveyed along the second conveying device 200 can receive heat and pressure from the heating unit 300 and the pressurizing unit 400.

[0084] The second conveying plate 520 can be formed as a flat plate, and the thickness of the second conveying plate 520 can be relatively thinner than the thickness of the all-solid-state battery SB.

[0085] In one embodiment, the first conveying plate 510 and the second conveying plate 520 may be formed to have the same thickness.

[0086] For example, the thickness of the second conveyor plate 520 can be 1 mm or less, 0.5 mm or less, or 0.2 mm or less.

[0087] Therefore, the second conveying plate 520 is formed to be relatively thinner than the all-solid-state battery SB, so that the second conveying plate 520 can effectively protect the outer peripheral surface of the all-solid-state battery SB, and at the same time effectively transfer heat or pressure from the outside to the outer peripheral surface of the all-solid-state battery SB.

[0088] Figure 5 for Figure 1 Enlarged view of part A in the middle.

[0089] Reference Figures 3 to 5 According to an embodiment of the present invention, the first fixing part 530 fixes the first conveying plate 510 to the first conveying device 100, and the first fixing part 530 may include a first fixing member 531, a first through member 532 and a first support member 533.

[0090] Reference Figure 4 and Figure 5 The first fixing member 531 is fastened to the first conveying device 100 and can be connected to the first conveying device 100 and the first conveying plate 510 respectively.

[0091] The first fixing member 531 can be positioned opposite to the second conveying plate 520 with reference to the first conveying plate 510.

[0092] Specifically, the first conveying plate 510 can be located between the first fixing member 531 and the second conveying plate 520, and the first fixing member 531 is connected to the first conveying plate 510 but can be spaced apart from the second conveying plate 520.

[0093] When viewed from one direction in which the first conveyor plate 510 and the second conveyor plate 520 are stacked (hereinafter referred to as the "stack direction"), the first fastener 531 may be spaced apart from the second through member 542 described below.

[0094] Specifically, when viewed from the stacking direction, the first fastener 531 can overlap with the first conveying plate 510, the second conveying plate 520 and the second fastener 541, but can be spaced apart from the second through member 542.

[0095] Therefore, even if the first conveying plate 510 and the second conveying plate 520 are compressed in a direction that brings them closer to each other, mechanical interference between the first fixing member 531 and the second through member 542 can be avoided.

[0096] There may be a plurality of first fixing members 531. Specifically, the first fixing members 531 may be located in front of and behind the first conveying plate 510 in the direction of movement.

[0097] The first fixing member 531 can be fixed in position to the first conveying device 100 by the first support member 533.

[0098] Reference Figure 5 The first conveying device 100 may include: a first chain body 110 that moves along an infinite track; and a first connecting portion 120 that protrudes from the first chain body 110 toward one side of the first chain body 110.

[0099] The first fixing member 531 can be fixed in position to the first connecting portion 120 by the first support member 533. Specifically, the first support member 533 can pass through both the first fixing member 531 and the first connecting portion 120, so that the first support member 533 can fix the position of the first fixing member 531 to the first connecting portion 120.

[0100] Therefore, the first conveying plate 510 connected to the first fixing member 531 can be fixed to the first conveying device 100.

[0101] In one embodiment, the first support 533 may be formed by various means capable of securing the first fastener 531 to the first conveying device 100. For example, the first support 533 may be formed by bolt and nut assembly, clamp, bracket, rivet, welded structure, adhesive or fastener device, etc.

[0102] The first through member 532 is used to connect the first conveying plate 510 and the first fixing member 531. The first through member 532 is connected to the first fixing member 531 and can pass through the first conveying plate 510.

[0103] For example, a first front hole 511 is formed on the front side of the first conveying plate 510, a first rear slit 512 is formed on the rear side of the first conveying plate 510, and the first fastener 531 can be configured to pass through the first front hole 511 and the first rear slit 512.

[0104] The term "front side" is interpreted as the area in front of the first conveying plate 510 in its direction of movement, and the term "rear side" is defined as the area further back than the front side, based on the direction of movement of the first conveying plate 510.

[0105] The first front hole 511 can be formed into a circular hole shape, thereby corresponding to the shape of the outer peripheral surface of the first through member 532.

[0106] Thus, the first through member 532 is inserted into the first front hole 511, thereby enabling the first conveying plate 510 and the first fixing member 531 to be fixed in position relative to each other, and correspondingly, the first conveying plate 510 can be moved by the movement of the first conveying device 100 connected to the first fixing member 531.

[0107] The first rear slit 512 can be formed as a long slit shape extending along the moving direction of the first conveying plate 510.

[0108] Specifically, the length of the first rear slit 512 extending along the moving direction of the first conveying plate 510 can be relatively longer than the length of the first front hole 511 extending along the moving direction of the first conveying plate 510.

[0109] The first through member 532, which is disposed through the first rear slit 512, can move along the first rear slit 512, and thereby the first conveying plate 510 can move relative to the first fixing member 531 corresponding to the rear slit.

[0110] Therefore, even if the first conveying plate 510 bends when it moves along the first conveying device 100 in a curved manner, the rear side of the first conveying plate 510 can move flexibly relative to the first fixing member 531 while being connected to the first fixing member 531.

[0111] Therefore, even if the first conveying plate 510 moves along a curved path, the first fixing part 530 can flexibly connect the first conveying plate 510 to the first conveying device 100.

[0112] The first penetrating member 532 can penetrate both the first conveying plate 510 and the second conveying plate 520 simultaneously.

[0113] When viewed from the stacking direction, the first through member 532 and the second conveying plate 520 can be spaced apart from each other.

[0114] Specifically, a through hole 523 may be formed in a region on the second conveying plate 520 corresponding to the longitudinal central axis of the first through member 532, and the end of the first through member 532 that passes through the first fixing member 531 and the first conveying plate 510 in sequence may be located inside the through hole 523 without contacting the second conveying plate 520.

[0115] Therefore, even if the end of the first through member 532 protrudes from the first conveying plate 510 toward the second conveying plate 520, interference between the first through member 532 and the second conveying plate 520 can be prevented by forming a through hole 523 on the second conveying plate 520.

[0116] Thus, the first through member 532 securely fixes the first conveying plate 510 to the first fixing member 531 without interfering with the second conveying plate 520.

[0117] In one embodiment, the first through member 532 may be formed by various means capable of securing the first conveying plate 510 to the first fastener 531. For example, the first through member 532 may be formed by bolts, nuts, clamps, brackets, rivets, welded structures, adhesives, or fasteners.

[0118] Figure 6 for Figure 1 Enlarged view of section B.

[0119] Reference Figure 3 , Figure 4 and Figure 6 According to an embodiment of the present invention, the second fixing part 540 fixes the second conveying plate 520 to the second conveying device 200, and the second fixing part 540 may include a second fixing member 541, a second through member 542 and a second support member 543.

[0120] Reference Figure 4 and Figure 6 The second fastener 541 is fastened to the second conveying device 200 and can be connected to the second conveying device 200 and the second conveying plate 520 respectively.

[0121] The second fixing member 541 can be positioned opposite to the first conveying plate 510 with reference to the second conveying plate 520.

[0122] Specifically, the second conveying plate 520 can be located between the second fixing member 541 and the first conveying plate 510, and the second fixing member 541 is connected to the second conveying plate 520 but can be spaced apart from the first conveying plate 510.

[0123] When viewed from the stacking direction, the second fastener 541 can be spaced apart from the first through-hole 532 described below.

[0124] Specifically, when viewed from the stacking direction, the second fastener 541 can overlap with the first conveying plate 510, the second conveying plate 520 and the first fastener 531, but can be spaced apart from the first through member 532.

[0125] Therefore, even if the first conveying plate 510 and the second conveying plate 520 are compressed in a direction that brings them closer to each other, mechanical interference between the second fixing member 541 and the first through member 532 can be avoided.

[0126] There may be a plurality of second fixing members 541. Specifically, the second fixing members 541 may be located in front of and behind the second conveying plate 520 in the direction of movement.

[0127] The second fixing member 541 can be fixed in position to the second conveying device 200 by the second support member 543.

[0128] Reference Figure 6 The second conveying device 200 may include: a second chain body 210 that moves along an infinite track; and a second connecting portion 220 that protrudes from the second chain body 210 toward one side of the second chain body 210.

[0129] The second fixing member 541 can be fixed in position to the second connecting portion 220 by the second support member 543. Specifically, the second support member 543 can pass through both the second fixing member 541 and the second connecting portion 220, so that the second support member 543 can fix the position of the second fixing member 541 to the second connecting portion 220.

[0130] Therefore, the second conveying plate 520, which is connected to the second fixing member 541, can be fixed to the second conveying device 200.

[0131] In one embodiment, the second support 543 may be formed by various means capable of securing the second fastener 541 to the second conveying device 200. For example, the second support 543 may be formed by bolt and nut assembly, clamp, bracket, rivet, welded structure, adhesive or quick-release device, etc.

[0132] The second through member 542 is used to connect the second conveying plate 520 and the second fixing member 541. The second through member 542 is connected to the second fixing member 541 and can pass through the second conveying plate 520.

[0133] For example, a second front hole 521 is formed on the front side of the second conveying plate 520, a second rear slit 522 is formed on the rear side of the second conveying plate 520, and the second fastener 541 can be configured to pass through the second front hole 521 and the second rear slit 522.

[0134] The term "front side" is interpreted as the area in front of the second conveying plate 520 in its direction of movement, and the term "rear side" is defined as the area further back than the front side, based on the direction of movement of the second conveying plate 520.

[0135] The second front hole 521 can be formed into a circular hole shape, thereby corresponding to the shape of the outer peripheral surface of the second through member 542.

[0136] Thus, the second through member 542 is inserted into the second front hole 521, so that the second conveying plate 520 and the second fixing member 541 can be fixed in position relative to each other, and correspondingly, the second conveying plate 520 can be moved by the movement of the second conveying device 200 connected to the second fixing member 541.

[0137] The second rear slit 522 can be formed as a long slit shape extending along the moving direction of the second conveying plate 520.

[0138] Specifically, the length of the second rear slit 522 extending along the moving direction of the second conveying plate 520 can be relatively longer than the length of the second front hole 521 extending along the moving direction of the second conveying plate 520.

[0139] The second through member 542, which is disposed through the second rear slit 522, can move along the second rear slit 522, and thereby the second conveying plate 520 can move relative to the second fixing member 541 corresponding to the rear slit.

[0140] Therefore, even if the second conveying plate 520 bends when it moves along the second conveying device 200 in a curved manner, the rear side of the second conveying plate 520 can move flexibly relative to the second fixing member 541 while being connected to the second fixing member 541.

[0141] Therefore, even if the second conveying plate 520 moves along a curved path, the second fixing part 540 can flexibly connect the second conveying plate 520 to the second conveying device 200.

[0142] When viewed from the stacking direction, the second through member 542 and the first conveying plate 510 can be spaced apart from each other.

[0143] Specifically, when viewed from the stacking direction, the longitudinal central axis of the first through-hole 532 can be located outside the first conveying plate 510. (Ref) Figure 7 )

[0144] Therefore, even if the end of the second through member 542 protrudes from the second conveying plate 520 toward the first conveying plate 510, interference between the second through member 542 and the first conveying plate 510 can be prevented by setting the first conveying plate 510 at a position spaced apart from the second through member 542.

[0145] Thus, the second through member 542 securely fixes the second conveying plate 520 to the second fixing member 541 without interfering with the first conveying plate 510.

[0146] In other words, the first through member 532 can avoid interference with the second conveying plate 520 by passing through the through hole 523 of the second conveying plate 520 while passing through the first conveying plate 510, and the second through member 542 can avoid interference with the first conveying plate 510 by passing through the second conveying plate 520 while being spaced apart from the first conveying plate 510.

[0147] In one embodiment, the second through member 542 may be formed by various means capable of securing the second conveying plate 520 to the second fastener 541. For example, the second through member 542 may be formed by bolts, nuts, clamps, brackets, rivets, welded structures, adhesives, or quick-release devices.

[0148] Figure 7 for Figure 3 The top view of the all-solid-state battery mounting device 500 shown is shown. Figure 8 for Figure 3 The bottom view of the all-solid-state battery mounting device 500 shown.

[0149] Figure 7 and Figure 8 This is a view taken from the stacking direction of the first transport plate 510 and the second transport plate 520, specifically, Figure 7 This is a view of the all-solid-state battery mounting device 500 as seen from the upper side in the stacking direction. Figure 8 This is a view of the all-solid-state battery mounting device 500 as seen from the lower side in the stacking direction.

[0150] Reference Figure 4 , Figure 7 and Figure 8 One side of the first conveying plate 510 and one side of the second conveying plate 520 can be located between the first fixing part 530 and the second fixing part 540.

[0151] The area of ​​the side of the first conveying plate 510 located between the first fixing part 530 and the second fixing part 540 and the area of ​​the side of the second conveying plate 520 located between the first fixing part 530 and the second fixing part 540 may be different.

[0152] For example, the area of ​​the side of the first conveying plate 510 located between the first fixing part 530 and the second fixing part 540 may be smaller than the area of ​​the side of the second conveying plate 520 located between the first fixing part 530 and the second fixing part 540.

[0153] Reference Figure 7 When viewed from the stacking direction, the first fastener 531 can be spaced apart from the second through-hole 542.

[0154] Therefore, even if the first conveying plate 510 and the second conveying plate 520 are in close contact, damage caused by the contact between the first fixing member 531 and the second through member 542 can be prevented.

[0155] Reference Figure 7 When viewed from the stacking direction, the first conveying plate 510 can be spaced apart from the second through member 542.

[0156] Therefore, even if the first conveying plate 510 and the second conveying plate 520 are in close contact, it can prevent the first conveying plate 510 from being damaged due to contact with the second through member 542.

[0157] Reference Figure 8 When viewed from the stacking direction, the second fastener 541 can be spaced apart from the first through-hole 532.

[0158] Therefore, even if the first conveying plate 510 and the second conveying plate 520 are in close contact, damage caused by the contact between the second fixing member 541 and the first through member 532 can be prevented.

[0159] Reference Figure 8 When viewed from the stacking direction, the second conveying plate 520 can be spaced apart from the first through member 532.

[0160] Specifically, when viewed from the stacking direction, the first through member 532 can overlap with the through hole 523 formed on the second conveying plate 520.

[0161] Therefore, even if the first conveying plate 510 and the second conveying plate 520 are in close contact, it can prevent the second conveying plate 520 from being damaged due to contact with the first through member 532.

[0162] According to an embodiment of the present invention, the all-solid-state battery fixing device 500 and the all-solid-state battery conveying system 1 including the device include a first conveying plate 510 and a second conveying plate 520.
