Description

Method for manufacturing an all-solid-state battery and apparatus for manufacturing an all-solid-state battery

[0001] The present invention relates to a method for manufacturing an all-solid-state battery and an apparatus for manufacturing an all-solid-state battery, and more specifically, to a method for manufacturing an all-solid-state battery and an apparatus for manufacturing an all-solid-state battery that improves the efficiency of a process for separating an outer body, a die plate, and a battery cell after a wet isotropic pressurization process.

[0002]

[0003] Recently, all-solid-state batteries, in which liquid electrolytes are replaced with solid electrolytes, have been proposed. An all-solid-state battery is a battery formed by stacking a positive electrode, a solid electrolyte, and a negative electrode and then pressurizing and densifying them; it utilizes a solid electrolyte instead of the liquid electrolyte found in conventional rechargeable batteries. By not using flammable organic dispersion media, all-solid-state batteries can significantly reduce the likelihood of fire or explosion even in the event of a short circuit. Consequently, these all-solid-state batteries can possess high stability.

[0004] All-solid-state batteries can be manufactured through various manufacturing processes, among which the wet isotropic pressurization process is a process in which a battery cell is placed on a die plate, the battery cell and the die plate are wrapped in an outer body, and then isotropically pressurized using a fluid.

[0005] After the wet isotropic pressurization process, an additional process is required to separate the outer body, die plate, and battery cell.

[0006]

[0007] The problem that the present invention aims to solve is to provide a method for manufacturing an all-solid-state battery and an apparatus for manufacturing an all-solid-state battery that improves the efficiency of the process of separating the outer body, the die plate, and the battery cell after a wet isotropic pressurization process.

[0008]

[0009] A method for manufacturing an all-solid-state battery according to the concept of the present invention comprises: cutting an outer body surrounding a battery cell and a die plate; removing the outer body from the battery cell and the die plate; separating the battery cell from the die plate; discharging the battery cell; and discharging the die plate; wherein the battery cell comprises a plurality of battery cells, and the plurality of battery cells are respectively disposed on one side and the other side of the die plate, and the outer body comprises a first outer film and a second outer film, wherein the first outer film surrounds the one side of the die plate and the second outer film surrounds the other side of the die plate, and removing the outer body may include simultaneously peeling off the first and second outer films from the one side and the other side of the die plate.

[0010] According to the concept of the present invention, an all-solid-state battery manufacturing apparatus comprises: an outer body cutting unit for cutting an outer body surrounding a battery cell and a die plate; an outer body removal unit for removing the outer body from the battery cell and the die plate; a battery cell separation unit for separating the battery cell from the die plate; a battery cell discharge unit for discharging the battery cell; and a die plate discharge unit for discharging the die plate; wherein the battery cell comprises a plurality of battery cells, and the plurality of battery cells are respectively disposed on one side and the other side of the die plate, and the outer body comprises a first outer film and a second outer film, wherein the first outer film surrounds the one side of the die plate and the second outer film surrounds the other side of the die plate, and the outer body removal unit may be configured to simultaneously peel off the first and second outer films from the one side and the other side of the die plate.

[0011]

[0012] The all-solid-state battery manufacturing method and all-solid-state battery manufacturing apparatus according to the present invention can improve the efficiency of the process of separating an outer body, a die plate, and a battery cell after a wet isotropic pressurization process.

[0035]

[0036] FIG. 1 discloses a unit cell shape of an all-solid-state battery cell (10) according to embodiments of the present invention.

[0037] Referring to FIG. 1, the all-solid-state battery cell (10) may include a positive electrode layer (20), a negative electrode layer (30) facing the positive electrode layer (20), and a solid electrolyte layer (40) disposed between the positive electrode layer (20) and the negative electrode layer (30). However, not limited thereto, the all-solid-state battery cell (10) may further include an additional functional layer, such as an adhesion enhancing layer, disposed between the positive electrode layer (20) and the solid electrolyte layer (40) or between the negative electrode layer (30) and the solid electrolyte layer (40).

[0038] The positive layer (20) may include a positive current collector (21) and a positive active material layer (23) disposed on the positive current collector (21). The positive active material layer (23) may include a positive active material, a solid electrolyte, a conductive material, and a binder.

[0039] The positive current collector (21) can provide a reference surface on which the positive active material layer (23) is placed. The positive current collector (21) may have a plate or foil form. For example, the positive current collector (21) may include indium (In), copper (Cu), magnesium (Mg), stainless steel, titanium (Ti), iron (Fe), cobalt (Co), nickel (Ni), zinc (Zn), aluminum (Al), germanium (Ge), lithium (Li), or an alloy thereof.

[0040] Unlike as illustrated in FIG. 1, in one embodiment of the present invention, the positive current collector (21) may be omitted. Although not illustrated, a carbon layer with a thickness of 0.1 μm to 4 μm may be further disposed between the positive current collector (21) and the positive active material layer (23) to increase the bonding strength between the positive current collector (21) and the positive active material layer (23).

[0041] The positive electrode active material may be a material capable of reversibly absorbing and desorbing lithium ions. For example, the positive electrode active material may include lithium transition metal oxides such as lithium cobalt oxide (LCO), lithium nickel oxide, lithium nickel cobalt oxide, lithium nickel cobalt aluminum oxide (NCA), lithium nickel cobalt manganese oxide (NCM), lithium manganate, and lithium iron phosphate, nickel sulfide, copper sulfide, lithium sulfide, iron oxide, or vanadium oxide, but is not limited thereto. The positive electrode active material may be a single material or a mixture of two or more materials.

[0042] Lithium transition metal oxides are, for example, Li a A 1-b B b D2(0.90≤a≤1, 0≤b≤0.5), Li a E 1-b B b O 2-c D c (0.90≤a≤1, 0≤b≤0.5, 0≤c≤0.05), LiE 2-b B b O 4-c D c (0≤b≤0.5, 0≤c≤0.05), Li a Ni 1-b-c Co b B c D α (0.90≤a≤1, 0≤b≤0.5, 0≤c≤0.05, 0<α<2), Li a Ni 1-b-c Co b B c O 2-α F α (0.90≤a≤1, 0≤b≤0.5, 0≤c≤0.05, 0<α<2), Li a Ni 1-b-c Mn b B c D α(0.90≤a≤1, 0≤b≤0.5, 0≤c≤0.05, 0<α≤2), Li a Nor 1-b-c Mn b B c O 2-α F α (0.90≤a≤1, 0≤b≤0.5, 0≤c≤0.05, 0<α<2), Li a Nor b E c G d O2(0.90≤a≤1, 0≤b≤0.9, 0≤c≤0.5, 0.001≤d≤0.1), Li a Nor b Co c Mn d GeO2(0.90≤a≤1, 0≤b≤0.9, 0≤c≤0.5, 0≤d≤0.5, 0.001≤e≤0.1), Li a NiG b O2(0.9≤a≤1, 0.001≤b≤0.1), Li a CoG b O2(0.90≤a≤1, 0.001≤b≤0.1), Li a MnG b O2(0.90≤a≤1, 0.001≤b≤0.1), Li a Mn2GbO4(0.90≤a≤1, 0.001≤b≤0.1), QO2, QS2, LiQS2, V2O5, LiV2O5, LiIO2, LiNiVO4, Li 3-f J2(PO4)3(0≤f≤2), Li 3-fIt may be a compound represented by any one of Fe2(PO4)3 (0≤f≤2) or LiFePO4. In such a compound, the uppercase “A” is Ni, Co, Mn, or a combination thereof; the uppercase “B” is Al, Ni, Co, Mn, Cr, Fe, Mg, Sr, V, a rare earth element, or a combination thereof; the uppercase “D” is O, F, S, P, or a combination thereof; the uppercase “E” is Co, Mn, or a combination thereof; the uppercase “F” is F, S, P, or a combination thereof; the uppercase “G” is Al, Cr, Mn, Fe, Mg, La, Ce, Sr, V, or a combination thereof; the uppercase “Q” is Ti, Mo, Mn, or a combination thereof; the uppercase “I” is Cr, V, Fe, Sc, Y, or a combination thereof; and the uppercase “J” is V, Cr, Mn, Co, Ni, Cu, or a combination thereof.

[0043] The positive electrode active material may include, for example, a lithium salt of a transition metal oxide having a layered rock salt type structure among the lithium transition metal oxides described above. The "layered rock salt type structure" is, for example, a cubic rock salt type structure. <111> It is a structure in which oxygen and metal atomic layers are alternately and regularly arranged in a specific direction, thereby forming a two-dimensional plane for each atomic layer. The "cubic rock salt type structure" represents a sodium chloride (NaCl) type structure, which is a type of crystal structure; specifically, it exhibits a structure in which face-centered cubic lattices (fcc) formed by cations and anions, respectively, are offset from each other by half the ridge of the unit lattice. Lithium transition metal oxides having such a layered rock salt type structure are, for example, LiNi x Co y Al z O2(NCA) or LiNi x Co y Mnz O2(NCM) (0 <x<1,0<y<1, 0<z<1, x+y+z=1) 등의 삼원계 리튬전이금속산화물일 수 있다. 양극 활물질이 층상암염형 구조를 갖는 삼원계 리튬전이금속산화물을 포함하는 경우, 전고체 전지 셀(10)의 에너지 밀도가 커지고 열안정성이 향상될 수 있다.

[0044] The aforementioned compound contained in the positive electrode active material may be covered by a coating layer (not shown). The positive electrode active material may also be a mixture of the aforementioned compound and the compound to which the coating layer is added. Meanwhile, the coating layer added to the surface of the positive electrode active material may include, for example, oxides, hydroxides, oxyhydroxides, oxycarbonates, or hydroxycarbonates of the following coating elements. The compounds forming this coating layer may be amorphous or crystalline. The coating elements included in the coating layer may include Mg, Al, Co, K, Na, Ca, Si, Ti, V, Sn, Ge, Ga, B, As, Zr, or mixtures thereof. The coating layer may include, for example, Li2O-ZrO2 (LZO). The method for forming the coating layer may be selected within a range that does not adversely affect the physical properties of the positive electrode active material. The method for forming the coating layer may include, for example, spray coating or immersion methods.

[0045] When the positive active material is a ternary lithium transition metal oxide such as NCA or NCM and contains nickel (Ni), the capacity density of the all-solid-state battery cell (10) can be increased, and the metal leaching of the positive active material in the charged state can be reduced. As a result, the cycle characteristics of the all-solid-state battery cell (10) in the charged state can be improved. Meanwhile, “cycle characteristics” is a characteristic that indicates the degree of deterioration of the all-solid-state battery cell (10) due to charging and discharging of the all-solid-state battery cell (10). An all-solid-state battery cell (10) with high cycle characteristics has a small degree of deterioration due to charging and discharging, while an all-solid-state battery cell (10) with low cycle characteristics may have a large degree of deterioration due to charging and discharging.

[0046] The shape of the positive electrode active material may include particle shapes such as spheres or ellipsoids. The particle size and content of the positive electrode active material are not particularly limited.

[0047] The solid electrolyte may include a sulfide-based solid electrolyte with excellent lithium ion conductivity characteristics. Sulfide-based solid electrolytes include, for example, Li2S-P2S5, Li2S-P2S5-LiX (where X is a halogen element), Li2S-P2S5-Li2O, Li2S-P2S5-Li2O-LiI, Li2S-SiS2, Li2S-SiS2-LiI, Li2S-SiS2-LiBr, Li2S-SiS2-LiCl, Li2S-SiS2-B2S3-LiI, Li2S-SiS2-P2S5-LiI, Li2S-B2S3, and Li2S-P2S5-Z m S n (m, n are positive numbers, uppercase “Z” is one of Ge, Zn, or Ga), Li2S-GeS2, Li2S-SiS2-Li3PO4, Li2S-SiS2-Li p MO q (p, q are positive numbers, uppercase “M” is one of P, Si, Ge, B, Al, Ga, In), Li 7-x PS 6-x Clx (0≤x≤2), Li 7-x PS 6-x Br x (0≤x≤2), and Li 7-x PS 6-x I x It may include at least one selected from (0≤x≤2).

[0048] Sulfide-based solid electrolytes are, for example, Li 7-x PS 6-x Cl x (0≤x≤2), Li 7-x PS 6-x Br x (0≤x≤2), and Li 7-x PS 6-x I x It may be an argyrodite-type compound comprising one or more selected from (0≤x≤2). In particular, the sulfide-based solid electrolyte may be an argyrodite-type compound comprising one or more selected from Li6PS5Cl, Li6PS5Br, and Li6PS5I. The density of the argyrodite-type solid electrolyte may be 1.5 g / cc to 2.0 g / cc. By having a density of 1.5 g / cc or higher for the argyrodite-type solid electrolyte, the internal resistance of the all-solid-state battery is reduced, and defects such as penetration and short circuit of the solid electrolyte film due to lithium dendrite formation can be prevented. The elastic modulus of the solid electrolyte may be, for example, 15 GPa to 35 GPa.

[0049] The solid electrolyte included in the positive electrode active material layer (23) may have a smaller average particle size (D50) of intermediate particle size compared to the solid electrolyte included in the solid electrolyte layer (40). For example, the average particle size (D50) of the solid electrolyte included in the positive electrode active material layer (23) may be 90% or less, 80% or less, 70% or less, 60% or less, 50% or less, 40% or less, 30% or less, or 20% or less of the average particle size (D50) of the solid electrolyte included in the solid electrolyte layer (40). Meanwhile, the average particle size (D50) may be a median diameter measured using a laser particle size distribution meter.

[0050] The positive active material layer (23) may include a conductive material. The conductive material may have conductivity without causing chemical changes in the all-solid-state battery cell (10), thereby increasing the conductivity of the positive active material and the solid electrolyte. The conductive material may include a carbon-based material. The conductive material may include, for example, one or more selected from graphite, carbon black, acetylene black, carbon nanofibers, and carbon nanotubes.

[0051] The positive active material layer (23) may further include a binder. The binder may include a material for bonding the positive active material, solid electrolyte, and conductive material contained in the positive active material layer (23), and for improving the bonding strength with the positive current collector (21). For example, the binder may include polyvinylidene fluoride, styrene butadiene rubber (SBR), polytetrafluoroethylene, polyvinylidene fluoride, vinylidene fluoride / hexafluoropropylene copolymer, polyacrylonitrile, or polymethyl methacrylate.

[0052] When the total of the positive active material, solid electrolyte, conductive material, and binder is 100 parts by weight, the positive active material layer (23) may include 85 to 92 parts by weight of the positive active material. The positive active material layer (23) may include 0.5 to 1.5 parts by weight of the binder.

[0053] In the positive active material layer (23), the conductive material may have 1 to 50 parts by weight per 100 parts by weight of solid electrolyte. If the conductive material is less than 1 part by weight per 100 parts by weight of solid electrolyte, the electrical conductivity of the positive active material layer (23) may be reduced. If the conductive material is more than 50 parts by weight per 100 parts by weight of solid electrolyte, the ratio of the conductive material is excessively high, so a coating layer covering the surface of the solid electrolyte may not be properly formed.

[0054] According to the embodiments, the positive active material layer (23) may further include at least one additive selected from the group consisting of a filler, a coating agent, a dispersant, and an ion-conducting aid, in addition to the positive active material, solid electrolyte, conductive material, and binder described above.

[0055] The solid electrolyte layer (40) is disposed between the positive electrode layer (20) and the negative electrode layer (30) and may include a sulfide-based solid electrolyte with excellent lithium ion conductivity characteristics. The solid electrolyte included in the solid electrolyte layer (40) may be the same as or different from any one of the materials that may be included in the solid electrolyte included in the aforementioned positive electrode active material layer (23).

[0056] The solid electrolyte layer (40) of one embodiment may include a sulfide-based solid electrolyte. The sulfide-based solid electrolyte may be manufactured by processing starting materials, such as Li2S or P2S5, by a melt quenching method or a mechanical milling method. Additionally, heat treatment may be performed after such processing. The solid electrolyte may be amorphous, crystalline, or a mixture thereof. Furthermore, the solid electrolyte may include sulfur (S), phosphorus (P), and lithium (Li) as at least constituent elements among the sulfide-based solid electrolyte materials described above, for example. For example, the solid electrolyte may be a material containing Li2S-P2S5. When using a sulfide-based solid electrolyte material containing Li2S-P2S5 to form the solid electrolyte, the molar ratio of Li2S and P2S5 is, for example, in the range of Li2S : P2S5 = 50 : 50 to 90 : 10.

[0057] Sulfide-based solid electrolytes are, for example, Li 7-x PS 6-x Cl x (0≤x≤2), Li 7-x PS 6-x Br x (0≤x≤2), and Li 7-x PS 6-x I xIt may be an argyrodite-type compound comprising one or more selected from (0≤x≤2). In particular, the sulfide-based solid electrolyte may be an argyrodite-type compound comprising one or more selected from Li6PS5Cl, Li6PS5Br, and Li6PS5I. The density of the argyrodite-type solid electrolyte may be 1.5 g / cc to 2.0 g / cc. By having a density of 1.5 g / cc or higher for the argyrodite-type solid electrolyte, the internal resistance of the all-solid-state battery is reduced, and defects such as penetration and short circuits of the solid electrolyte film due to lithium dendrite formation can be prevented. The elastic modulus of the solid electrolyte is, for example, 15 GPa to 35 GPa.

[0058] The solid electrolyte layer (40) may further include a binder. The binder in the solid electrolyte layer (40) is not limited to, for example, styrene butadiene rubber (SBR), polytetrafluoroethylene, polyvinylidene fluoride, polyethylene, etc. The binder of the solid electrolyte layer (40) may be the same as or different from the binder included in the positive active material layer (23) or the binder included in the coating layer (33).

[0059] The negative electrode layer (30) may include a negative electrode current collector (31) and a coating layer (33) on the negative electrode current collector (31). The negative electrode current collector (31) may provide a reference surface on which the coating layer (33) is placed. The negative electrode current collector (31) may include, for example, a material that does not react with lithium, that is, does not form any alloys or compounds with lithium. For example, the negative electrode current collector (31) may include at least one metal selected from the group consisting of copper (Cu), stainless steel, titanium (Ti), iron (Fe), cobalt (Co), and nickel (Ni). The thickness of the negative electrode current collector (31) may be 1 μm to 20 μm, more specifically 5 μm to 15 μm, and more specifically 7 μm to 10 μm.

[0060] The negative current collector (31) may be composed of one of the metals described above, or may include an alloy of two or more metals or a coating material. The negative current collector (31) may, for example, have a plate-like or foil-like shape. Meanwhile, in one embodiment, the negative current collector (31) may be omitted.

[0061] The coating layer (33) can allow lithium metal to grow between the all-solid-state battery cell (10) and the negative current collector (31) during charging. The coating layer (33) can serve as a protective layer for the lithium metal and simultaneously suppress the precipitation and growth of lithium dendrites.

[0062] The coating layer (33) may include metal and carbon. For example, the coating layer (33) may include at least one metal selected from the group consisting of gold (Au), platinum (Pt), palladium (Pd), silicon (Si), silver (Ag), aluminum (Al), bismuth (Bi), tin (Sn), and zinc (Zn). The coating layer (33) may include at least one carbon selected from the group consisting of carbon black, acetylene black, furnace black, ketjen black, and graphene. In one embodiment, the coating layer (33) may include a mixture of carbon black and silver (Ag).

[0063] The coating layer (33) may further include other additives in addition to metal and carbon. The coating layer (33) may further include at least one additive selected from the group consisting of, for example, binders, fillers, coating agents, dispersants, and ion-conducting aids.

[0064] The coating layer (33) may have a smaller thickness compared to the positive active material layer (23). The thickness of the coating layer (33) may be, for example, 50% or less, 40% or less, 30% or less, 20% or less, 10% or less, or 5% or less of the thickness of the positive active material layer (23). The thickness of the coating layer (33) may be, for example, 1 µm to 20 µm, 2 µm to 10 µm, or 3 µm to 7 µm. If the thickness of the coating layer (33) is excessively thin, lithium dendrites formed between the coating layer (33) and the negative current collector (31) may cause the coating layer (33) to collapse, thereby degrading the cycle characteristics of the all-solid-state battery cell (10). If the thickness of the coating layer (33) increases excessively, the energy density of the all-solid-state battery cell (10) decreases, and the internal resistance of the all-solid-state battery cell (10) due to the coating layer (33) increases, which may degrade the cycle characteristics of the all-solid-state battery cell (10).

[0065] Meanwhile, although not shown, a carbon layer may be further included to improve adhesion between the coating layer (33) and the solid electrolyte layer (40).

The die plate (DP) may include a metal having sufficient rigidity to prevent bending and warping of the all-solid-state battery cell (EC) when a pressurization process is performed on the battery cell (EC). For example, the die plate (DP) may include a hard metal such as SUS (Steel Use Stainless).

[0072] A battery cell (EC) may include a plurality of battery cells (EC). A plurality of battery cells (EC) may be disposed on one side (DP5) and the other side (DP6) of a die plate (DP). In other words, a plurality of battery cells (EC) may be disposed on both sides of the die plate (DP).

[0073] A lower release film (BAF) can be placed on each of the one side (DP5) and the other side (DP6) of the die plate (DP).

The release film suction device (514) can be connected to the block beam (512) and the block actuator (515). Although not shown in the drawing, the release film suction device (514) can be connected to an external suction device and piping. As the suction device is driven, the release film suction device (514) can suction the upper release film (TAF).

[0184] A block actuator (515) may be placed on a block beam (512). The block actuator (515) may enable the release film adsorber (514) to easily separate the upper release film (TAF) from the battery cell (EC).

A release film adsorber (514) may be placed at the rod end of the block actuator (515).

[0185] The block actuator (515) can finely separate the upper release film (TAF) from the battery cell (EC).

[0186] Subsequently, as disclosed in FIG. 9, the third moving part (520) can be driven to move the release film adsorber (514) away from the battery cell. The release film adsorber (514) can stably separate the upper release film (TAF) from the battery cell (EC).

[0187] The release film adsorber (514) can simultaneously remove multiple upper release films (TAF) from multiple battery cells (EC) arranged on both sides of the die plate (DP).

[0188]

[0189] Referring to FIG. 3, the battery cell discharge section (130) can discharge the battery cell (EC) separated from the die plate (DP) to the outside. Afterwards, the battery cell (EC) can be loaded into a magazine, etc.

[0190] Referring to FIG. 3, the die plate discharge section (140) can discharge the die plate (DP) from which the battery cell (EC) has been separated to the outside. At this time, a lower release film (BAF) may be attached to each of the one side (DP5) and the other side (DP6) of the die plate (DP).

[0191] The die plate (DP) and bottom release film (BAF) can be reused.

[0192] A battery cell (EC) can be placed on a die plate (DP) and a lower release film (BAF), and an upper release film (TAF) can be wrapped around the upper part of the battery cell (EC). Then, a pressure assembly (GU) can be formed by wrapping the die plate (DP), the lower release film (BAF), the battery cell (EC), and the upper release film (TAF) with an outer body (PF).

[0193] The pressurizing assembly (GU) is fed into a wet isotropic pressurizing device, and the battery cell (EC) can be isotropically pressurized.

[0194] Afterwards, the pressure assembly (GU) is stored in a tray, and the tray input section (110) can transfer the pressure assembly (GU) to the outer body cutting section (200).

[0195] In an embodiment of the present invention, the battery cell discharge unit (130) and the die plate discharge unit (140) may each be a logistics device.

[0196]

[0197] The configuration of the all-solid-state battery manufacturing apparatus (100) according to an embodiment of the present invention is as described above, and the all-solid-state battery manufacturing method will be explained below.

[0198] FIG. 10 discloses an embodiment of the method for manufacturing an all-solid-state battery according to the present invention.

[0199] Referring to FIG. 10, one embodiment of the method for manufacturing an all-solid-state battery according to the present invention may include cutting an outer body (PF) surrounding a battery cell (EC) and a die plate (DP) (S1), removing the outer body (PF) from the battery cell (EC) and the die plate (DP) (S2), separating the battery cell (EC) from the die plate (DP) (S3), discharging the battery cell (EC) (S4), and discharging the die plate (DP) (S5).

[0200]

[0201] Cutting the outer body (PF) surrounding the battery cell (EC) and the die plate (DP) (S1) allows the outer body cutting portion (200) to cut some of the multiple joint portions (BP) formed on the outer body (PF).

[0202] Referring to FIG. 4a, the tray input section (110) can take a pressure assembly (GU) out of the tray and place it on the cutting die (240). Although not shown in the drawing, a structure capable of fixing the position of the pressure assembly (GU) may be provided on the cutting die (240). Thus, the position of the pressure assembly (GU) placed on the upper part of the cutting die (240) can be fixed. The cutting die (240) may be connected to the first movable frame (MB1). The first movable frame (MB1) may be movably positioned on the first linear guide device (LIN1).

[0203] The control unit can operate the first linear guide device (LIN1) to position the first moving frame (MB1) at the bottom of the cutting member (230).

[0204] Referring to FIG. 4b, the first moving frame (MB1) is shown moving along the longitudinal direction of the first linear guide device (LIN1) and positioned at the bottom of the cutting member (230).

[0205] The control unit can operate the cutting drive unit (220) to cause the cutting member (230) to move toward the pressure assembly (GU). In an embodiment of the present invention, the cutting drive unit (220) may be a hydraulic cylinder. Accordingly, the control unit can operate the hydraulic cylinder to cause the rod (220a) to move downward.

[0206] The cutting member (230) moves downward, and the cutting member (230) can cut the edge of the outer body (PF). At this time, a plurality of posts (225) can guide the upward and downward movement of the cutting member (230).

[0207] Referring to FIG. 4d, first to third cutting blades (233 to 235) may be arranged in the lower part of the cutting block (231).

[0208] In addition, first to fourth joints (BP1 to BP4) may be formed on the edges of the outer body (PF).

[0209] Each of the first to third cutting blades (233 to 235) can simultaneously cut the first to third joints (BP1 to BP3).

[0210] The non-cutting portion (238) can be fixed on the cutting die (240) by pressing the first joint portion (BP1), thereby allowing the first to third joint portions (BP1~BP3) to be stably cut.

[0211] Accordingly, the edges of the outer body (PF) can be left open on the remaining three sides, excluding the fourth joint (BP4).

[0212] Referring to FIGS. 5a and 5b, it can be seen that the first to third joints (BP1 to BP3) formed on the outer body (PF) have been cut and removed.

[0213] In this step (S1), the outer body cutting part (200) can simultaneously remove the first to third joints (BP1~BP3) on the outer body (PF) and leave only the fourth joint (BP4) of the outer body (PF).

[0214] Accordingly, as disclosed in FIG. 5b, the outer body (PF) can be transferred to the outer body removal unit (300) with the fourth joint (BP4) remaining joined and the remaining three sides open.

[0215] Referring to FIG. 4c, after the cutting of the outer body (PF) is completed, the control unit can operate the first linear guide device (LIN1) to move the first moving frame (MB1) toward the outer body removal unit (300).

[0216]

[0217] Removing the outer body (PF) from the battery cell (EC) and the die plate (DP) (S2) can simultaneously peel off the first and second outer films (PF1, PF2) from one side (DP5) and the other side (DP6) of the die plate (DP).

[0218] Specifically, it may include holding and positioning the pressure assembly (GU) in the air, adsorbing the first and second outer films (PF1, PF2), and simultaneously peeling off the first and second outer films (PF1, PF2) from the battery cell (EC) and the die plate (DP).

[0219] Referring to FIG. 6, the control unit can operate the first grip unit (330) to grasp the pressure assembly (GU) on the cutting die (240). The first grip unit (330) can move the pressure assembly (GU) to the third direction (D3) so that the pressure assembly (GU) is positioned in the air.

[0220] Referring to FIG. 7a, the control unit operates the first grip unit (330) so that the first grip unit (330) can move the pressure assembly (GU) toward the outer body suction unit (310). Afterward, the control unit can stop the movement of the first grip unit (330) to fix the position of the pressure assembly (GU) in the air.

[0221] Referring to FIG. 7b, the control unit can operate the suction unit moving unit (316) to move a pair of support arms (312) in the direction of the pressure assembly (GU) as indicated by the arrow. Accordingly, a pair of outer body suction units (313) can come into contact with the surface of the outer body (PF). Specifically, the outer body suction unit (313) positioned at the top can come into contact with the first outer film (PF1), and the outer body suction unit (313) positioned at the bottom can come into contact with the second outer film (PF2).

[0222] Subsequently, the control unit may operate the suction device to cause the outer body suction device (313) to suction the surface of the outer body (PF). Accordingly, the first outer film (PF1) can be firmly suctioned to the upper outer body suction device (313), and the second outer film (PF2) can be firmly suctioned to the lower outer body suction device (313).

[0223] Referring to FIG. 7c, the control unit can operate the adsorber moving unit (316) to move a pair of support arms (312) away from the pressure assembly (GU) as indicated by the arrow. Accordingly, a pair of outer body adsorbers (313) can cause the edge of the outer body (PF) to be separated from the battery cell (EC).

[0224] At this time, the upper release film (TAF) can be separated from the battery cell (EC) together with the outer body (PF). Referring to FIG. 7c, the state in which the outer body (PF) and the upper release film (TAF) are peeled off together can be observed.

[0225] Subsequently, the control unit can operate the arm drive unit (315). In an embodiment of the present invention, the arm drive unit (315) may be a hydraulic cylinder. Thus, the rod (315a) of the arm drive unit (315) is extended and can rotate the link arm (314). As the link arm (314) rotates, the outer body suction device (313) can rotate in the direction of the arrow disclosed in FIG. 7c.

[0226] Referring to FIG. 7d, the control unit can operate the first moving unit (320) to move the outer body adsorption unit (310) toward the fourth joint (BP4).

[0227] In other words, the outer body adsorption unit (310) can be moved from the front side (DP1; see FIG. 5b) of the die plate (DP) to the rear side (DP4; see FIG. 5b).

[0228] Accordingly, the outer body adsorber (313) moves the first and second outer films (PF1, PF2) toward the fourth joint (BP4) and can peel them off from the battery cell (EC) and the die plate (DP).

[0229] The first grip unit (330) holds the rear portion (DP4) of the die plate (DP). In order to completely remove the outer body (PF) from the battery cell (EC) and the die plate (DP), the second grip unit (340) must hold the front portion (DP1) of the die plate (DP).

[0230] Referring to FIG. 7e, the control unit can operate the second grip unit (340) so that the second grip unit (340) grasps the front side (DP1) of the die plate (DP). Then, the second grip unit (340) can be moved in the opposite direction of the first grip unit (330) so that the outer body (PF) is completely removed from the battery cell (EC) and the die plate (DP).

[0231] Afterward, the control unit may stop the operation of the suction device and allow the outer body (PF) to be separated from the outer body suction device (313). The outer body (PF) may fall downward due to gravity. Although not shown in the drawing, an outer body collection container may be provided at the bottom of the outer body removal unit (300). The outer body (PF) may be collected in the outer body collection container.

[0232]

[0233] Separating the above battery cell (EC) from the die plate (DP) (S3) can simultaneously peel off a plurality of battery cells (EC) from one side (DP5) and the other side (DP6) of the die plate (DP).

[0234] Specifically, it may include adsorbing a plurality of battery cells (EC) and simultaneously separating the plurality of battery cells (EC) from one side (DP5) and the other side (DP6) of the die plate (DP).

[0235] Referring to FIG. 8a, the control unit can move the second grip unit (340) to transfer the die plate (DP) and the battery cell (EC) to the battery cell separator (400). Accordingly, the die plate (DP) and the battery cell (EC) can be positioned between a pair of cell adsorption units (410).

[0236] Referring to FIG. 8b, the control unit can operate the second moving unit (420) to move a pair of cell adsorption units (410) toward the battery cell (EC).

[0237] A pair of cell adsorbers (414) can be in contact with multiple battery cells (EC).

[0238] The control unit can operate the suction device to allow a pair of cell adsorbers (414) to adsorb multiple battery cells (EC).

[0239] Subsequently, the control unit may operate the adsorption actuator (415) to cause the battery cell (EC) to be finely separated from the lower release film (BAF). In an embodiment of the present invention, the adsorption actuator (415) may be a hydraulic cylinder. Accordingly, the control unit may finely pull the rod (415a) of the adsorption actuator (415) in the direction of the arrow to cause the battery cell (EC) adsorbed on the cell adsorber (414) to be finely separated from the lower release film (BAF).

[0240] Referring to FIG. 8c, the control unit can operate the second moving unit (420) to move a pair of cell adsorption units (410) away from the die plate (DP). Accordingly, the pair of cell adsorption units (410) can simultaneously separate a plurality of battery cells (EC) from one side (DP5) and the other side (DP6) of the die plate (DP).

[0241] Referring to FIG. 8d, the control unit can operate the adsorber rotation unit (413). The adsorber rotation unit (413) can rotate the support beam (412) and the cell adsorber (414) by about 90°. Accordingly, the battery cell (EC) can be positioned to face downward.

[0242] Subsequently, the control unit can operate the lifting unit (430). The lifting unit (430) can move the support beam (412) and the cell adsorber (414) along the third direction (D3). In other words, the lifting unit (430) can move the battery cell (EC) downward. Accordingly, the battery cell (EC) can be placed on the carrier (CR).

[0243] The control unit can operate the second linear guide device (LIN2). The second linear guide device (LIN2) can move the second moving frame (MB2) toward the battery cell discharge unit (130).

[0244]

[0245] Discharging the battery cell (EC) (S4) allows the battery cell discharge unit (130) to discharge the battery cell (EC) on the second moving frame (MB2) to the outside and load it into a magazine, etc. Although not shown in the drawing, a separate logistics device can load the battery cell (EC) into a magazine, etc.

[0246] Discharging the die plate (DP) (S5) allows the die plate discharge unit (140) to discharge the die plate (DP) from which the battery cell (EC) has been separated to the outside. Although not illustrated in the drawing, a separate logistics device may transport the die plate (DP) so that it can be reused.

[0247] At this time, a lower release film (BAF) may be attached to each of the one side (DP5) and the other side (DP6) of the die plate (DP).

[0248] The die plate (DP) and bottom release film (BAF) can be reused.

[0249] Subsequently, a battery cell (EC) can be placed on a die plate (DP) and a lower release film (BAF), and an upper release film (TAF) can be wrapped around the top of the battery cell (EC). Then, a pressure assembly (GU) can be formed by wrapping the die plate (DP), the lower release film (BAF), the battery cell (EC), and the upper release film (TAF) with an outer body (PF).

[0250] The pressurized cooking body is fed into a wet isotropic pressurizing device, and the battery cell (EC) can be isotropically pressurized.

[0251] Afterwards, the pressure assembly (GU) is stored in a tray, and the tray input section (110) can transfer the pressure assembly (GU) to the outer body cutting section (200).

[0252] Through the process steps described above, one embodiment of the all-solid-state battery manufacturing method of the present invention can improve manufacturing process efficiency by rapidly and stably separating the outer body (PF) and the battery cell (EC) after undergoing a wet isotropic pressurization process.

[0253]

[0254] FIG. 11 discloses another embodiment of the method for manufacturing an all-solid-state battery according to the present invention.

[0255] Referring to FIG. 11, another embodiment of the method for manufacturing an all-solid-state battery according to the present invention may include cutting an outer body (PF) surrounding a battery cell (EC) and a die plate (DP) (S1), removing the outer body (PF) from the battery cell (EC) and the die plate (DP) (S2), detecting an upper release film (TAF) (S2a), determining whether the upper release film (TAF) is detected (S2b), removing the upper release film (TAF) from the battery cell (EC) (S2c), separating the battery cell (EC) from the die plate (DP) (S3), discharging the battery cell (EC) (S4), and discharging the die plate (DP) (S5).

[0256] Cutting the outer body (PF) surrounding the battery cell (EC) and the die plate (DP) (S1), removing the outer body (PF) from the battery cell (EC) and the die plate (DP) (S2), separating the battery cell (EC) from the die plate (DP) (S3), discharging the battery cell (EC) (S4), and discharging the die plate (DP) (S5) are identical to the process steps described above, so please refer to the above description.

[0257] Below, we will explain detecting the upper release film (TAF) (S2a), determining whether the upper release film (TAF) is detected (S2b), and removing the upper release film (TAF) from the battery cell (EC) (S2c).

[0258]

[0259] Detecting the upper release film (TAF) (S2a) allows the vision unit (150) to detect whether the upper release film (TAF) is present on the battery cell (EC). As described above, when the outer body removal unit (300) removes the outer body (PF), the upper release film (TAF) may be removed together. After the outer body (PF) is removed, the vision unit (150) can detect whether the upper release film (TAF) remains on the battery cell (EC).

[0260] Determining the presence or absence of the upper release film (TAF) (S2b) can be done by the control unit determining whether there is an upper release film (TAF) on the battery cell (EC). If the vision unit (150) does not detect the upper release film (TAF) (No), the control unit operates the battery cell separation unit (400), and the battery cell separation unit (400) can perform the separation of the battery cell (EC) from the die plate (DP) (S3).

[0261] When the vision unit (150) detects the upper release film (TAF) (e.g.), the control unit operates the release film removal unit (500), and the release film removal unit (500) can perform the removal of the upper release film (TAF) from the battery cell (EC) (S2c).

[0262] Removing the upper release film (TAF) from the battery cell (EC) (S2c) is performed by the control unit operating the release film removal unit (500), and the release film removal unit (500) can remove the upper release film (TAF) from the battery cell (EC).

[0263] The control unit can move the second grip unit (340) toward the release film removal unit (500).

[0264] The release film removal unit (500) can simultaneously remove the first upper release film (TAF1) and the second upper release film (TAF2) from the battery cell (EC).

[0265] Specifically, it may include adsorbing the first and second upper release films (TAF1, TAF2) and simultaneously separating the first and second upper release films (TAF1, TAF2) from the battery cell (EC).

[0266] Referring to FIG. 9, the control unit can move the second grip unit (340) to transfer the die plate (DP), battery cell (EC), and upper release film (TAF) to the release film removal unit (500). Accordingly, the die plate (DP), battery cell (EC), and upper release film (TAF) can be positioned between a pair of release film adsorption units (510).

[0267] The control unit can operate the third moving unit (520) to move a pair of release film adsorption units (510) toward the first and second upper release films (TAF1, TAF2).

[0268] A pair of release film adsorbers (514) can be in contact with the first and second upper release films (TAF1, TAF2).

[0269] The control unit can operate the suction device to cause a pair of release film adsorbers (514) to adsorb the first and second upper release films (TAF1, TAF2).

[0270] Subsequently, the control unit may operate the block actuator (515) to cause the first and second upper release films (TAF1, TAF2) to be finely separated from the battery cell (EC). In an embodiment of the present invention, the block actuator (515) may be a hydraulic cylinder. Accordingly, the control unit may finely pull the rod (515a) of the block actuator (515) to cause the first and second upper release films (TAF1, TAF2) adsorbed to the release film adsorber (514) to be finely separated from the battery cell (EC).

[0271] The control unit can operate the third moving unit (520) to move a pair of release film adsorption units (510) away from the die plate (DP). Accordingly, the pair of release film adsorption units (510) can simultaneously separate the first and second upper release films (TAF1, TAF2), respectively, from the battery cell (EC).

[0272] The control unit can operate the adsorber rotation unit (513). The adsorber rotation unit (513) can rotate the block beam (512) and the release film adsorber (514) by about 90°.

[0273] The control unit can stop the suction device so that the upper release film (TAF) is separated from the release film suction device (514). The upper release film (TAF) can fall downward by gravity and be collected in a release film collection container.

[0274] Subsequently, the control unit may perform the separation (S3) of the battery cell (EC) from the die plate (DP). As described above, the battery cell separation unit (400) and the release film removal unit (500) may be the same device. Alternatively, the battery cell separation unit (400) and the release film removal unit (500) may be different devices.

[0275]

[0276] The all-solid-state battery manufacturing method and all-solid-state battery manufacturing apparatus (100) according to the present invention can improve the efficiency of the process of separating the outer body (PF), the die plate (DP), and the battery cell (EC) after the wet isotropic pressurization process through the manufacturing process and configuration described above. The outer body (PF) covering one side (DP5) and the other side (DP6) of the die plate (DP) can be peeled off simultaneously, and a plurality of battery cells (EC) placed on one side (DP5) and the other side (DP6) of the die plate (DP) can be separated simultaneously.

[0277] This can increase the productivity of secondary batteries and improve product reliability.
