Recently, as the manufacturing cost per unit capacity of secondary batteries has decreased dramatically due to improved energy density and economies of scale, and as the driving range of BEVs (battery electric vehicles) has increased to a level equivalent to that of fuel vehicles, the primary use of secondary batteries is shifting from mobile devices to mobility.

[0003] The manufacturing process for secondary batteries (such as lithium-ion batteries) is complex and requires very high precision. The capabilities of operators who directly operate the manufacturing facilities have a significant impact on overall aspects, including production efficiency, product quality, safety, and cost management.

[0004] Operators managing secondary battery manufacturing facilities are key personnel in the factory. They must possess process knowledge, safety protocols, and problem-solving skills to stably produce high-quality products, while simultaneously reducing defect rates and costs and enhancing corporate competitiveness. Therefore, companies must establish and implement systematic and continuous training programs for operators. Through this, safety and efficiency across the entire battery manufacturing process can be maximized, and companies can proactively respond to intensifying market competition and regulatory changes in the future.

[0047]

[0048] Referring to FIGS. 1 through 8, a secondary battery manufacturing system (10000) may be configured to perform a secondary battery manufacturing process. The secondary battery manufacturing system (10000) may include a secondary battery manufacturing facility (1000), a server (2000), and a Human-Machine Interface (HMI) (3000).

[0049] The secondary battery manufacturing facility (1000) may be configured to perform, for example, an assembly process. More specifically, the secondary battery manufacturing system (1000) may be configured to perform, for example, an assembly process of a can-type battery cell (BC).

[0050] For example, a secondary battery manufacturing facility (1000) may be configured to process a cylindrical cell can (CC) of a battery cell (BC). The secondary battery manufacturing facility (1000) may be configured to form a cylindrical can (CC) of a battery cell (BC). The secondary battery manufacturing facility (1000) may include a sub-facility (1100), a sub-facility (1200), and a sub-facility (1300).

[0051] Prior to being processed by the secondary battery manufacturing facility (1000), a series of processes may be performed on the battery cell (BC) and the elements of the battery cell (BC). For example, to provide the battery cell (BC), a positive electrode current collector (PC) and a negative electrode current collector (NC) are joined (e.g., welded) to a jelly roll (JR), an insulating tape (TF) is attached to the positive electrode of the jelly roll (JR), an insulator (INS) is inserted into a can (CC), a jelly roll (JR) is inserted into the can (CC), a rivet (RV) of the positive electrode current collector (PC) and the can (CC) is joined, the can (CC) is formed so that a beading portion (CCB) is formed in a part of the can (CC) adjacent to the opening (CCO) of the can (CC), a negative electrode current collector (NC) is fixed to the beading portion (CCB) of the can (CC), an X-RAY inspection is performed on the workpiece, and an electrolyte may be injected into the can (CC). Here, the beading section (CCB) is a recessed structure along the outer diameter of the can (CC).

Sizing is a process of reducing the total height of a battery cell (BC) by pressing the top of the battery cell (BC) so that the height of the neck of the beading portion (CCB) is reduced.

[0053] After the battery cell (BC) is processed by the secondary battery manufacturing facility (1000), the battery cell (BC) may be cleaned, the appearance of the battery cell (BC) may be inspected, and the electrical characteristics of the battery cell (BC) may be inspected. The inspection of the electrical characteristics of the battery cell (BC) may include measuring the internal resistance and measuring the open circuit voltage of the battery cell (BC).

[0054] Here, the jelly roll (JR) may include a wound structure of an anode, a cathode, and a separator. The anode may include an anode current collector and an anode active material, and the cathode may include a cathode current collector and a cathode active material.

[0055] The thickness of the positive current collector may be in the range of about 3 μm to about 500 μm. The positive current collector may not cause chemical changes in the secondary battery finally manufactured and may have high conductivity. The positive current collector may include, for example, stainless steel, nickel, titanium, calcined carbon, and aluminum. The positive current collector may also include stainless steel surface-treated with carbon, nickel, titanium, silver, etc. The surface of the positive current collector may include a micro-roughness structure to increase the adhesion of the active material. The positive current collector may have the shape of a film, sheet, foil, net, porous material, foam, nonwoven fabric, etc.

The cathode active material may be, for example, a layered compound such as lithium cobalt oxide (LiCoO2) and lithium nickel oxide (LiNiO2) substituted with one or more transition metals, lithium manganese oxide substituted with one or more transition metals, or a material with the chemical formula LiNi 1-y M y A lithium nickel-based oxide represented by O2 (where M is any one of Co, Mn, Al, Cu, Fe, Mg, B, Cr, Zn, and Ga, and 0.01≤y≤0.7), Li 1+z Ni 1 / 3 Co 1 / 3 Mn 1 / 3 O2, Li 1+zN i 0.4 Mn 0.4 Co 0.2 Li like O2 1+z Ni b Mnc Co 1-(b+c+d) M d O (2-e) A e A lithium nickel cobalt manganese composite oxide represented by the formula Li, where -0.5≤z≤0.5, 0.1≤b≤0.8, 0.1≤c≤0.8, 0≤d≤0.2, 0≤e≤0.2, b+c+d<1, M is any one of Al, Mg, Cr, Ti, Si, and Y, and A is any one of F, P, and Cl. 1+x M 1-y M' y PO 4-z X z It may include an olivine-based lithium metal phosphate represented as (wherein M is a transition metal, more specifically one of Fe, Mn, Co and Ni, M' is one of Al, Mg and Ti, X is one of F, S and N, -0.5≤x≤+0.5, 0≤y≤0.5, and 0≤z≤0.1).

[0057] The thickness of the negative current collector may be in the range of about 3 μm to about 500 μm. The negative current collector may not cause chemical changes in the secondary battery finally manufactured and may have high conductivity. The negative current collector may include copper, stainless steel, aluminum, nickel, titanium, calcined carbon, and aluminum-cadmium alloy. The negative current collector may also include stainless steel surface-treated with carbon, nickel, titanium, silver, etc. The surface of the negative current collector may include a micro-roughness structure to increase the adhesion of the active material. The negative current collector may have the shape of a film, sheet, foil, net, porous material, foam, nonwoven fabric, etc.

[0058] The negative electrode active material may include carbon, for example, non-graphitizable carbon, graphite-based carbon, etc. The negative electrode active material is, for example, Li x Fe2O3(0≤x≤1), LixWO2(0≤x≤1), Sn x Me1-x Me y O z (Here, Me is any one of Mn, Fe, Pb, and Ge, and Me' is any one of Al, B, P, Si, Group 1, Group 2, and Group 3 elements of the periodic table and halogens, and 0 <x≤1이고, 1≤y≤3 이며, 1≤z≤8) 등의 금속 복합 산화물을 포함할 수 있다. 음극 활물질은, 예컨대, 리튬 금속, 리튬 합금, 규소계 합금, 주석계 합금을 포함할 수 있다. 음극 활물질은, 예컨대, SnO, SnO2, PbO, PbO2, Pb2O3, Pb3O4, Sb2O3, Sb2O4, Sb2O5, GeO, GeO2, Bi2O3, Bi2O4, Bi2O5등의 금속 산화물을 포함할 수 있다. 음극 활물질은, 예컨대, 폴리아세틸렌 등의 도전성 고분자, Li-Co-Ni 계 재료 등을 포함할 수 있다.

[0059] The sub-equipment (1100) and the sub-equipment (1200) may be configured to crimp a can (CC). The sub-equipment (1100) may be configured to perform a first crimping process and a second crimping process on the can (CC). The sub-equipment (1200) may be configured to perform a third crimping process on the can (CC).

[0060] The opening (CCO) can be closed by the sub-equipment (1100) and the sub-equipment (1200). In the first crimping, the opening (CCO) can be bent at a first angle, in the second crimping, the opening (CCO) can be bent at a second angle, and in the third crimping, the opening (CCO) can be bent at a third angle and the can (CC) can be closed.

[0061] The sub-equipment (1300) may be configured to perform a sizing process on the can (CC). Before adjusting the total height of the can (CC), the data matrix of the can (CC) may be read out. By applying external pressure to the can (CC) using a punch press or the like, the height of the beading portion (CCB) of the can (CC) may be reduced, and accordingly, the total height of the can (CC) may be adjusted. Subsequently, the outer diameter of the can (CC) may be measured, and a 3D inspection may be performed on the can (CC). Defective battery cells (BC) may be discharged, and good battery cells (BC) may be transferred to the sub-equipment (240) for a subsequent process.

[0062] The sub-equipment (1100) may include processing devices (1110), an inspection device (1120), processing devices (1130), and an inspection device (1140). The processing devices (1130) are generally similar to the processing devices (1110), except that they perform secondary crimping instead of primary crimping. The inspection device (1140) is generally similar to the inspection device (1120).

[0063] The processing mechanism (1110) may include a three-jaw chuck (1111), a spindle (1113), and an inspection device (1115). The three-jaw chuck (1111) may include a housing (1111H) and jaws (1111J) coupled to the housing (1111H). Each jaw (1111J) may be configured to move relative to the housing (1111H). Each jaw (1111J) may be configured to move toward or away from the center of the housing (1111H). Springs (1111S) may be interposed between the housing (1111H) and the jaws (1111J).

[0064] Each jaw (1111J) may include a tip (1111JT) that is inserted into the beading section (CCB). The tip (1111JT) of each jaw (1111J) may advance toward the can (CC) and be inserted into the beading section (CCB) as the spindle (1113) descends. The spindle (1113) may include a punch. As the spindle (1113) descends further, the punch of the spindle (1113) may press the opening (CCO) of the can.

[0065] Each tip (1111JT) of the jaws (1111J) is inserted into the beading section (CCB) and may have a relatively thin thickness, and thus may be easily damaged. Additionally, the punch of the spindle (1113) repeatedly applies mechanical processing to the can (CC), so it may wear out or even become damaged. Since damage to the punch of the jaws (1111J) and the spindle (1113) can cause repeated defects in the battery cell (BC), detecting damage to the punch of the jaws (1111J) and the spindle (1113) and replacing the damaged jaws (1111J) and the spindle (1113) early is very important for improving the yield of the battery cell (BC).

[0066] The inspection device (1115) may be configured to inspect the jaws (1111J) and the spindle (1113). The inspection device (1115) may be a type of vision machine. The inspection device (1115) may include an image sensor, such as a camera, and a processor configured to analyze an image captured by said image sensor.

[0067] The processor may be configured to determine damage to the jaws (1111J) and spindle (1113) based on images of the jaws (1111J) and spindle (1113). The processor may include an algorithm configured to determine damage to the jaws (1111J) and spindle (1113) based on images of the jaws (1111J) and spindle (1113). The processor may include a model trained based on images of normal jaws (1111J) and spindle (1113) and images of damaged jaws (1111J) and spindle (1113). The model may be configured to determine damage to the jaws (1111J) and spindle (1113).

[0068] A processor may be implemented in hardware, firmware, software, or combinations thereof. For example, a processor may include computing devices such as workstation computers, desktop computers, laptop computers, and tablet computers. A processor may include any one of a simple controller, a complex processor such as a microprocessor, CPU, GPU, etc., a processor configured by software, dedicated hardware, and firmware. A processor may be implemented by, for example, a general-purpose computer or by application-specific hardware such as a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), and an Application Specific Integrated Circuit (ASIC).

[0069] The operation of the processor may be implemented as instructions stored on a machine-readable medium that can be read and executed by one or more processors. Here, the machine-readable medium may include any mechanism for storing and / or transmitting information in a form readable by a machine (e.g., a computing device). For example, the machine-readable medium may include Read Only Memory (ROM), Random Access Memory (RAM), magnetic disk storage medium, optical storage medium, flash memory, electrical, optical, acoustic, or other forms of radio signals (e.g., carrier waves, infrared signals, digital signals, etc.) and any other signals.

[0070] The processor may be composed of firmware, software, routines, and instructions for performing the aforementioned operation or any process described below. For example, the processor may be implemented (instantiated) in memory.

[0071] The sub-equipment (1200) may include processing mechanisms (1210) and an inspection device (1220). The processing mechanisms (1210) are generally similar to the processing mechanisms (1110), except that they perform tertiary crimping instead of primary crimping. The inspection device (1220) is generally similar to the inspection device (1120).

[0072] The sub-equipment (1300) may include processing devices (1310) and an inspection device (1320). The processing devices (1310) are largely similar to the processing devices (1110), except that they perform sizing instead of primary crimping.

[0073] An inspection device (1120) may be configured to inspect the appearance of a battery cell (BC) processed by processing mechanisms (1110). An inspection device (1140) may be configured to inspect the appearance of a battery cell (BC) processed by processing mechanisms (1120). An inspection device (1220) may be configured to inspect the appearance of a battery cell (BC) processed by processing mechanisms (1210).

[0075] Here, problematic events may include Breakdown Maintenance (BM) and Process Down (PD). BM refers to the work of repairing machinery or equipment when it breaks down. In BM, repairs and maintenance are carried out only after a machine or system has failed, without any preventive measures. PD is a situation where the production process is halted. Factors contributing to PD primarily include machine breakdowns, material shortages, labor issues, or power and environmental factors.

[0076] The HMI (3000) can provide interaction between the secondary battery manufacturing facility (1000) and the operator (OP). The HMI (3000) can be configured to display data, generate control signals for controlling the secondary battery manufacturing facility (1000), generate alarms and warnings, and perform data recording and data recording analysis. Through the HMI (3000), operations such as starting, stopping, manual operation, and sample collection of the secondary battery manufacturing facility (1000) can be performed.
