Therefore, it should not be understood that the sizes or ratios of the components fully reflect their actual sizes or ratios.

[0036] Figure 1 is a block diagram illustrating a system 1000 according to an exemplary embodiment.

[0037] Reference Figure 1 , the system 1000 may include a resin composition applicator 1100 and a detection device 1200 .

[0038] The system 1000 can perform at least part of the process of manufacturing a secondary battery. The system 1000 can perform the battery module (see Figure 6a ) is at least a part of the manufacturing process. The system 1000 can be configured to mix the resin composition 130 (see Figure 2a ) is coated on the frame 110 (see Figure 2a ) and detect the resin composition 130.

[0039] The system 1000 may further include a conveying system 1300 that conveys the workpiece processed by the resin composition applicator 1100 to the detection device 1200. In synchronization with the operation of the resin composition applicator 1100, the conveying system 1300 may convey the workpiece that has completed the distribution process to the detection device 1200. The conveying system 1300 may be controlled by a supervisory control system and convey the workpiece to the detection device 1200 without operator intervention. Therefore, the takt time for manufacturing secondary batteries can be reduced and productivity can be improved. When an additional process (e.g., additional coating of the resin composition 130 (see Figure 2a ), the conveying system 1300 can return the workpiece to the resin composition applicator 1100.

[0040] The system 1000 may further include a buffer portion that temporarily stores the workpiece between the resin composition applicator 1100 and the inspection device 1200 .

[0041] Figure 2a and Figure 2b is a diagram illustrating a resin composition applicator 1100 according to an exemplary embodiment. More specifically, Figure 2a is a plan view of a resin composition applicator 1100, and Figure 2b 1100 is a front view of the resin composition applicator 1100 .

[0042] Reference Figure 2a and Figure 2b , the resin composition coater 1100 may include a jig 1110 and a dispenser 1120. The jig 1110 may be configured to support the frame 110. The jig 1110 may fix the frame 110 during coating of the resin composition 130. Therefore, a set portion of the frame 110 may be accurately coated with the resin composition 130, thereby improving the reliability of the dispensing process.

[0043] The dispenser 1120 may be configured to discharge the resin composition 130. As described below, the resin composition 130 may be applied to the battery cell block 120 (see Figure 6b) is fixed to the frame 110. Therefore, the resin composition 130 can be accurately coated on the battery cell block 120 to be mounted on the frame 110 (see Figure 6b )’s location.

[0044] The frame 110 may support the battery module 100 (see Figure 6b ) components. By placing the battery module 100 (see Figure 6b ) are sequentially assembled on the frame 11 to provide the battery module 100. For example, the frame 110 may include a metal material such as aluminum.

[0045] The frame 110 may include a bottom surface 110B and a side wall 110W. Therefore, when viewed from the front, the frame 110 may have a U-shape. Two directions substantially parallel to the bottom surface 110B of the frame 110 will be defined as an X-axis direction and a Y-axis direction, and a direction substantially perpendicular to the bottom surface 110B of the frame 110 will be defined as a Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction may be substantially perpendicular to each other.

[0046] The side wall 110W may be located at both ends of the bottom surface 110B. The side wall 110W may extend in the X-axis direction and be substantially perpendicular to the Y-axis direction. The side wall 110W may have a certain height from the bottom surface 110B in the Z-axis direction. As a non-limiting example, the length of the frame 110 in the X-axis direction may be longer than the length of the frame 110 in the Y-axis direction. Hereinafter, the X-axis direction may be referred to as the length direction of the frame 110, and the Y-axis direction may be referred to as the width direction of the frame 110.

[0047] According to an exemplary embodiment, the resin composition 130 may be a two-component resin composition. According to an exemplary embodiment, the resin composition 130 may include a main component (part A), a curing agent (part B), a dispersant, and an inorganic filler. The resin composition 130 may also include a viscosity modifier such as a thixotropic agent, a diluent, a surface treatment agent, or a coupling agent.

[0048] The resin composition 130 may be a room temperature curable composition. That is, the curing reaction of the resin composition 130 may be initiated and performed at room temperature.

[0049] As a non-limiting example, the main component of the resin composition 130 may be a silicone resin, a polyol resin, an epoxy resin, or an acrylic resin. In the resin composition 130, the curing agent of the resin composition 130 may be selected according to the main component of the resin composition 130. For example, when the main component of the resin composition 130 is a silicone resin, the curing agent may be a siloxane compound, when the main component of the resin composition 130 is a polyol resin, the curing agent may be an isocyanate compound, when the main component of the resin composition 130 is an epoxy resin, the curing agent may be an amine compound, and when the main component of the resin composition 130 is an acrylic resin, the curing agent may be an isocyanate compound.

[0050] The inorganic filler of the resin composition 130 may have a relatively high thermal conductivity. According to an exemplary embodiment, the thermal conductivity of the inorganic filler of the resin composition 130 may be about 1 W / mK or more. According to an exemplary embodiment, the thermal conductivity of the inorganic filler of the resin composition 130 may be about 5 W / mK or more. According to an exemplary embodiment, the thermal conductivity of the inorganic filler of the resin composition 130 may be about 10 W / mK or more. According to an exemplary embodiment, the thermal conductivity of the inorganic filler of the resin composition 130 may be about 15 W / mK or more.

[0051] According to an exemplary embodiment, the inorganic filler of the resin composition 130 may include ceramics. For example, the inorganic filler of the resin composition 130 may include one of aluminum oxide (Al2O3), aluminum nitride (AlN), boron nitride (BN), silicon nitride (Si3N4), silicon carbide (SiC), beryllium oxide (BeO), zinc oxide (ZnO), aluminum hydroxide (Al(OH)3), and boehmite. The resin composition 130 may include a carbon filler. For example, the resin composition 130 may include one of fumed silica, clay, and calcium carbonate.

[0052] The dispersant of the resin composition 130 may improve dispersibility of the inorganic filler of the resin composition 130. Therefore, the inorganic filler of the resin composition 130 may be uniformly distributed.

[0053] Figure 3a and Figure 3b 1 is a diagram illustrating a detection device 1200 according to an exemplary embodiment. More specifically, Figure 3a is a plan view of the detection device 1200, and Figure 3b It is a front view of the detection device 1200.

[0054] Reference Figure 3a and Figure 3b, the detection device 1200 may include a fixture 1210, a scanner 1220, and an analyzer 1230. The fixture 1210 may be configured to support the frame 110. During the detection of the resin composition 130, the fixture 1210 may fix the frame 110. Therefore, the frame 110 may be prevented from moving during the detection of the resin composition 130, and the reliability of the detection may be improved.

[0055] For example, the scanner 1220 may be a line scanner. The scanner 1220 may be configured to detect the resin composition 130 while moving in the X-axis direction. The scanner 1220 may be configured to sense the three-dimensional (3D) structure of the resin composition. The scanner 1220 may be configured to sense the 3D profile formed by the frame 110 and the resin composition 130. The 3D profile of the frame 110 and the resin composition 130 may be a set of physically outermost points on the structure formed by the frame 110 and the resin composition 130 on the frame 110. According to an exemplary embodiment, the 3D profile may be sensed with the bottom surface 110B of the frame 110 as a reference.

[0056] The analyzer 1230 may be configured to determine the area, volume, and mass of the resin composition 130 based on the detection result of the scanner 1220. The analyzer 1230 may be configured to determine the area, volume, and mass of the resin composition 130 based on the 3D profiles of the frame 110 and the resin composition 130 sensed by the scanner 1220.

[0057] The analyzer 1230 may be configured to determine the position of the coated resin composition 130 and the area of ​​the coated resin composition 130 based on the 3D profile of the frame 110 and the resin composition 130. The analyzer 1230 may be configured to determine the volume of the resin composition 130 based on the 3D profile of the frame 110 and the resin composition 130. The volume of the resin composition 130 may be calculated by integrating the height of the resin composition 130 at the position of the coated resin composition 130 determined by the analyzer 1230. For example, the volume V of the resin composition 130 may be determined by the following formula:

[0058] [Mode]

[0059] V = ∫hdxdy

[0060] Here, h represents the height of the resin composition 130 , dx represents the difference in x, and dy represents the difference in y.

[0061] The analyzer 1230 may be configured to determine the mass of the resin composition 130 based on the volume of the resin composition 130. The mass of the resin composition 130 may be calculated by performing an operation (eg, multiplying) the known density of the resin composition 130 determined by the analyzer 1230 and the volume of the resin composition 130.

[0062] Analyzer 1230 can be a computer device such as a workstation computer, a desktop computer, a laptop computer, or a tablet computer. Analyzer 1230 can be configured as a separate hardware component or can be a separate software included in each hardware component. Analyzer 1230 can be a simple controller, a microprocessor, a complex processor such as a CPU or GPU, a processor configured by software, dedicated hardware, or firmware. For example, analyzer 1230 can be implemented by a general-purpose computer or dedicated hardware (e.g., a digital signal processor (DSP), a field programmable gate array (FPGA), or an application-specific integrated circuit (ASIC)).

[0063] According to some embodiments, the operation of the analyzer 1230 may be implemented by instructions stored in a machine-readable medium, which may be read and executed by one or more processors. Here, the machine-readable medium may include a mechanism for storing and / or transmitting information in a form readable by a machine (e.g., a computer device). For example, the machine-readable medium may include a read-only memory (ROM), a random access memory (RAM), a magnetic disk storage medium, an optical storage medium, a flash memory device; electrical, optical, acoustic or other types of radio signals (e.g., carrier waves, infrared signals, digital signals, etc.), and other signals.

[0064] The firmware, software, routines and instructions may also be configured to perform the above operations of the analyzer 1230 or the processes described below. However, the above description is provided only for convenience of description, and it should be understood that the above operations of the analyzer 1230 may be performed by a computer device, processor, controller or other device for executing firmware, software, routines and instructions.

[0065] Figure 3c is a diagram for describing a scanner 1220 according to an exemplary embodiment.

[0066] The scanner 1220 may include a laser source 1221, an imaging lens 1223, and a detector 1225. The laser source 1221 may be configured to generate and emit an optical signal OS for sensing a 3D profile. The optical signal OS emitted from the laser source 1221 may be reflected from the surface of the detection object OT to be detected, focused on the imaging lens 1223, and reach the detector 1225. The detector 1225 may include a displacement sensor or a linear diode array.

[0067] The scanner 1220 can determine the height h of the detection object OT from the reference plane of the surface based on the position where the optical signal OS reflected from the surface of the detection object OT is focused on the detector 1225. As a non-limiting example, the reference point of the height h can be the frame 110 (see Figure 3b ) of the bottom surface 110B ( Figure 3b ).

[0068] The height h from the surface of the detection object OT can be calculated based on the displacement δx between the position where the optical signal OS reflected from the surface of the detection object OT is focused on the detector 1225 and the reference position on the detector 1225, and the angle θ between the laser source 1221 and the detector 1225. Here, the angle θ can be defined as the angle between the optical axis of the laser source 1221 and the optical axis of the detector 1225 in the free space optical system of the detection device 1220.

[0069] Although the detection device 1220 has been described above as an example of a displacement sensor type, it should be understood that the technical concept of the present disclosure is not limited to this in any sense. The detection device 1220 may be a time-of-flight (TOF) scanner. Here, the TOF scanner may measure the distance from the TOF scanner to the object to be detected by transmitting a signal to the object and measuring the time required to sense the signal reflected from the object. The signal of the TOF scanner may be an optical signal, a radio wave signal, or a terahertz wave signal.

[0070] Figure 4a and Figure 4b 1 is a diagram illustrating a resin composition applicator 1101 according to another exemplary embodiment. More specifically, Figure 4a is a plan view of the resin composition applicator 1101, and Figure 4b It is a front view of the resin composition applicator 1101.

[0071] Reference Figure 4a and Figure 4b , the resin composition coater 1101 may include a scanner 1220 , an analyzer 1230 , a jig 1110 , and a dispenser 1120 .

[0072] The fixture 1110 and the dispenser 1120 may be used with reference to Figure 2a and Figure 2b The above components of are substantially the same. The scanner 1220 and the analyzer 1230 can be used with reference Figure 3a and Figure 3b The above-mentioned components are substantially the same.

[0073] According to the embodiment, since the resin composition applicator 1101 includes the scanner 1220 and the analyzer 1230, the resin composition 130 may be immediately inspected without having to be transferred after dispensing the resin composition 130. Therefore, a tact time for manufacturing a battery module may be reduced.

[0074] The resin composition coater 1101 may include a driving device for moving the dispenser 1120. The driving device may provide a space for scanning by the scanner 1220 by moving the dispenser 1120 after the dispensing process.

[0076] Figure 6a is a perspective view of the battery module 100 .

[0077] Figure 6b yes Figure 6a FIG. 1 is an exploded perspective view of a battery module 100 .

[0078] Reference Figures 5 to 6b In P110, a resin composition 130 may be disposed on the frame 110. Figure 2a and Figure 2b The resin composition applicator 1100 is used to provide the resin composition 130 .

[0080] The battery cell block 120 may include a plurality of battery cells. Typically, the battery cell block 120 includes eight to twelve battery cells, and an expansion module including more than twenty-four battery cells has recently been proposed.

[0081] A battery cell is a basic unit of a lithium-ion battery (i.e., a secondary battery). A battery cell includes an electrode assembly, an electrolyte, and a housing. According to the configuration of the electrode assembly and the electrolyte, the battery cell is divided into a lithium-ion battery, a lithium-ion polymer battery, a lithium polymer battery, and the like. Lithium-ion polymer batteries are gaining market share in the field of secondary batteries due to their low likelihood of electrolyte leakage and ease of manufacture.

[0082] According to the shape of the battery case, the battery cells are classified into cylindrical batteries in which the electrode assembly is built in a cylindrical metal can, square batteries in which the electrode assembly is built in a square metal can, and pouch-type batteries in which the electrode assembly is built in a pouch case of an aluminum laminate.

[0083] The electrode assembly included in the battery case includes: a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode. According to the form of assembly, the electrode assembly can be classified as a wound electrode assembly or a stacked electrode assembly. The wound electrode assembly is manufactured by winding the positive electrode, the negative electrode, and the separator interposed between the positive electrode and the negative electrode. The stacked electrode assembly includes a plurality of positive electrodes, a plurality of negative electrodes, and a plurality of separators interposed therebetween, stacked in sequence.

The negative electrode collector may include: stainless steel, aluminum, nickel, titanium, baked carbon, and aluminum-cadmium alloy. The negative electrode collector may include stainless steel surface-treated with carbon, nickel, titanium, silver, etc. The surface of the negative electrode collector may include a fine uneven structure to increase the adhesion of the active material. The surface of the negative electrode collector may include a fine uneven structure to increase the adhesion of the active material.

[0087] The positive electrode active material is a material that can cause an electrochemical reaction. The positive electrode active material can be a lithium transition metal oxide. For example, the positive electrode active material may include: a layered compound substituted with one or more transition metals, such as lithium cobalt oxide (LiCoO2) or lithium nickel oxide (LiNiO2); a lithium manganese oxide substituted with one or more transition metals; a 1-y M y Lithium nickel-based oxide represented by the chemical formula Li O2 (wherein M is Co, Mn, Al, Cu, Fe, Mg, B, Cr, Zn or Ga, 0.01≤y≤0.7); l+z Ni b Mn c Co l-(b+c+d) M d O (2-e) A represents a lithium nickel cobalt manganese composite oxide, such as Li 1+z Ni1 / 3 Co 1 / 3Mn 1 / 3 O2 or Li 1+z Ni 0.4 Mn 0.4 Co 0.2 O2 (wherein, -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 Al, Mg, Cr, Ti, Si or Y, and A is F, P or Cl) or Li 1+ x M 1-y M' y PO 4-z X z Represented as an olivine-based lithium metal phosphate (herein, M is a transition metal, more specifically, Fe, Mn, Co or Ni, M' is Al, Mg or Ti, X is F, S or N, -0.5≤x≤+0.5, 0≤y≤0.5 and 0≤z≤0.1).

[0088] For example, the negative electrode active material may include carbon such as non-graphitizable carbon or graphite-based carbon. For example, the negative electrode active material may include Li x Fe2O3(0≤x≤1), Li x WO2(0≤x≤1) or Sn x Me 1-x Me' y O z (Here, Me is Mn, Fe, Pb or Ge, Me' is Al, B, P, Si, a Group I element, a Group II element or a Group III element of the periodic table or a halogen, 0<x≤1, 1≤y≤3 and 1≤z≤8) metal composite oxide. For example, the negative electrode active material may include: lithium metal, lithium alloy, silicon-based alloy and tin-based alloy.

For example, the negative electrode active material may include a conductive polymer such as polyacetylene, a Li-Co-Ni system material, etc.

[0089] Next, in P120, the resin composition 130 can be tested. Figure 3a and Figure 3b The resin composition 130 may be inspected by the inspection device 1200. The 3D profile formed by the frame 110 and the resin composition 130 may be determined by inspecting the resin composition 130.

[0090] Next, in P130, the mass and area of ​​the resin composition 130 may be determined, and it may be determined whether the mass and area of ​​the resin composition are within a normal range. Figure 3a to Figure 3c The contents described are substantially the same, so redundant descriptions thereof are omitted here. When the mass and area of ​​the resin composition 130 determined in P130 are not within a normal range (NG), the method may return to operation P110 to provide the resin composition 130 again.

[0091] In P140, when the mass and area of ​​the resin composition 130 determined in P130 are within the normal range (G), the battery cell block 120 may be combined with the frame 110. Before combining the battery cell block 120 to the frame 110, the compression pad 143, the front B / F assembly 151, the rear B / F assembly 153, and the FFC assembly 155 may be combined with the battery cell block 120.

[0092] The battery cell block 120 may be bonded to the frame 110 by the resin composition 130. The battery cell block 120 may be mounted on the frame 110 and overlap the resin composition 130. The frame 110 may cover the bottom surface and both side surfaces of the battery cell block 120. The bottom surface of the battery cell block 120 may face the resin composition 130 and the bottom surface 110B of the frame 110.
