    “SECONDARY BATTERY SET AND METHOD FOR MANUFACTURING THE SAME” Field of the Art The present invention relates to a secondary battery pack with improved safety and, more particularly, to a secondary battery set that includes an anode terminal of a cell battery, the anode terminal being made of a conductive element in plate shape, the anode terminal being electrically connected to a protection circuit module (PCM) through a safety element, a cathode terminal of the battery cell, the cathode terminal being made of a conductive element in the shape of a plate, the cathode terminal being electrically connected directly to the PCM, a battery cell that has the anode terminal and the terminal cathode formed at one end of it, and the battery cell is provided at the end of it with a surplus thermally welded part and a PCM that includes a p printed circuit board (PCB) which has a protection circuit formed on it, the PCB being provided on one side with a cathode terminal connection part and a security element connection part and on the other side the same side of an external input and output terminal connection part, an external input and output terminal electrically connected to the PCB protection circuit via the external input and output terminal connection part of the PCB, and a first housing and a second housing coupled to each other through a mounting type fixture to cover the PCB and the safety element, the PCM being loaded onto the thermally welded excess part of the battery cell in a state in which the PCM it is electrically connected to the safety element and the battery cell. Prior art As mobile devices have been progressively developed and the demand for such mobile devices has increased, the demand for secondary batteries has also increased significantly. Among such secondary batteries is a secondary lithium battery that exhibits high energy density and operating voltage and excellent preservation and service life characteristics, which have been widely used as a power source for various electronic products, as well as mobile devices. .
    However, several types of combustible materials are contained in the secondary lithium battery. As a consequence of this, the secondary lithium battery may become heated or explode due to battery overload, excessive current in the battery or other physical external impact. That is, the safety of the secondary lithium battery is very low. Consequently, safety elements, such as a positive temperature coefficient element (PTC) and a protection circuit module (PCM), to effectively control an abnormal state of the secondary lithium battery, such as battery overload secondary lithium battery or excessive current in the secondary lithium battery, are charged over the secondary lithium battery in a state in which the safety elements are connected to a battery cell.
    Generally, the PCM is connected to the battery cell via conductive nickel plates by means of welding or soft soldering. That is, the nickel plates are connected to PCM electrode tabs by welding or soft soldering, and then the nickel plates are connected to the corresponding electrode terminals of the battery cell by welding or soft soldering. In this way, the PCM is connected to the battery cell to manufacture a battery pack.
    The safety elements, which include the PCM, are required to be kept in electrical connection with the battery cell electrode terminals and, at the same time, be electrically isolated from other parts of the battery cell. Consequently, an insulating tape is generally attached to the PCM excluding the electrode terminal connection regions of the same to maintain electrical insulation, thereby achieving such a connection.
    In this case, however, it is difficult for the safety elements to immediately detect the temperature of the battery cell due to the insulation tape and, in addition, the mechanical resistance of the safety elements against external impact is low.
    In addition, if a plurality of insulating mounting elements or a plurality of parts are used to solve the problems mentioned above, a battery pack assembly process becomes complicated. When a large number of welding or soft soldering processes are performed to configure the battery pack, the welding or soft soldering processes need to be performed with high precision due to the small structure of the secondary battery. As a result, the possibility of a defect is great.
    Therefore, there is a great need for a technology that is capable of stably coupling the elements mounted on the upper end of a battery cell and, at the same time, simplifying an assembly process and improving the safety of the battery cell.
    Description Technical problem Therefore, the present invention has been made to solve the above problems and other technical problems that still need to be solved.
    Specifically, it is an objective of the present invention to provide a secondary battery pack that has a stable mounting structure obtained using a simplified mounting process, while maintaining mechanical strength and electrical insulation.
    Technical solution In accordance with one aspect of the present invention, the above and other objectives can be accomplished by providing a secondary battery pack that includes an anode terminal of a battery cell, the anode terminal being made of a conductive element in the form of a plate, the anode terminal being electrically connected to a protection circuit module (PCM) through a safety element, a cathode terminal of the battery cell, the cathode terminal being made of of a conductive element in the form of a plate, the cathode terminal being electrically connected directly to the PCM, a battery cell that has the anode terminal and the cathode terminal formed at one end of it, the cell being battery is equipped with a thermally welded surplus at the end, and a PCM that includes a printed circuit board (PCB) that has a protective circuit the PCB is provided with a cathode terminal connection part and a security element connection part on one side and an input terminal connection part and on the other side of it external output, an external input and output terminal electrically connected to the PCB protection circuit via the external input and output terminal connection part of the PCB, and a first enclosure and a second enclosure coupled to each other through a structure of mounting type fixture in order to cover the PCB and the safety element, the PCM being loaded over the thermally welded excess part of the battery cell in a state in which the PCM is electrically connected to the safety element and to the battery cell.
    Consequently, in the secondary battery pack according to the present invention, the PCM and the safety element are loaded onto the thermally welded surplus portion of the battery cell in a state in which the PCM and the safety element are mounted between the first wrapper and the second wrapper. As compared to a conventional secondary battery pack that uses insulation tape, therefore, it is possible to effectively protect the PCM and considerably reduce the number of parts, thereby greatly improving manufacturing processability.
    In addition, the first wrapper and the second wrapper are coupled to each other via an assembly-type fastening structure and, therefore, it is possible to significantly improve the efficiency of the process as compared to a case using an additional adhesive tape.
    As defined above, the first housing and the second housing according to the present invention are separate elements that are coupled to each other through an assembly-type fixture.
    In connection with this case, the first housing and the second housing can be connected to each other via an articulation structure so that the first housing and the second housing constitute a single unitary element. In this case, however, it may be difficult to form the first shell and the second shell by injection molding due to their small size. In addition, the strength of a hinge region is relatively low with the consequence that the first shell and the second shell can be easily damaged if the present invention is applied to real products. In addition, the sealing capacity and thus the resistance to moisture can be reduced due to the weak clamping force in the hinge region. In addition, the hinge region protrudes outward, with the consequence that the battery cell can be damaged during installation, and the capacity of the battery pack is reduced as compared to battery packs that have the same pattern. , since the excess space is necessary so that the articulation region can project. The fixing structure of the enclosure assembly type, according to the present invention, to solve the above problems, can be configured so that the first enclosure is provided with at least one fixation hole (or fixation protuberance), through the which the first enclosure is coupled to the second enclosure, and the second enclosure is provided with at least one fixation protrusion (or fixation orifice) that corresponds to the fixation orifice (or fixation protrusion) of the first enclosure.
    In such a coupling manner, the first housing and the second housing can be easily assembled and a coupled state between the first housing and the second housing can be additionally fixed in a stable manner. The fixing structure can consist, for example, of hooks.
    In addition, the at least one fixing hole and at least one fixing protuberance that corresponds to at least one fixing hole are preferably formed on the outer circumferential sides of the first and second casings that face each other, to achieve uniform coupling force and thereby increase the sealing force. For example, if the sides of the first and second casings that face each other form a rectangular shape, at least one fixing hole and at least one fixing protuberance that corresponds to at least one fixing hole can be formed on four sides of the first and second casing. In this structure, it is possible to increase the sealing force of the insulating mounting elements, thus improving the insulation and safety.
    Various types of battery cells can be used in the secondary battery pack according to the present invention. The battery cell used in the secondary battery pack according to the present invention may consist of a pocket-sized secondary battery, which has an electrode assembly of a cathode / separator / anode structure mounted in a battery housing made of a laminated sheet that includes a layer of metal and a layer of resin in a sealed state, of which the thickness and weight are small.
    As defined above, the PCB, which has the protection circuit to control overload, overload, excessive current, etc. of the battery, it is provided on one side of it with the cathode terminal connection part and the safety element connection part and on the other side of it with the external input and output terminal connection part.
    Consequently, it is possible to connect the cathode terminal of the battery cell to the cathode terminal connection part of the PCB without changing the shape and without using additional elements and connecting one side of the security element to the connection part of the PCB security element located on the same side of the PCM, in a state in which the anode terminal of the battery cell is connected to the other side of the security element. As a consequence of this, the safety element, the structural resistance is low, is stably mounted on the PCB, thus reducing a defect rate in a manufacturing process and, thus, improving the efficiency of the manufacturing process. The material for the cathode terminal connection part and the safety element connection part is not particularly restricted, as long as the cathode terminal connection part and the safety element connection part are made of a conductive material . It is preferred that the cathode terminal connection part and the security element connection part are made of nickel plates.
    In addition, each nickel plate can be configured to have a structure in which one end of each nickel plate is perpendicularly curved, while the other end of each nickel plate is attached to the rear side of the PCB , so that the nickel plates can be easily welded to the cathode terminal and the safety element.
    However, the safety element consists of an element whose resistance increases with increasing temperature. It is preferred that the safety element consists of a positive temperature coefficient (PTC) element. A connection element coupled to the PTC element serves to interrupt the current at the upper end of the battery pack when the temperature of the battery pack rises sharply due to an internal short circuit, or the like. However, the security element is not limited to the PTC element. For example, a bimetal or a fuse can be used as the security element.
    In a preferred example, the first housing or the second housing can be provided with an opening, through which the security element located on the PCM is exposed to the outside. The first housing and the second housing are preferably made of a plastic material in consideration of electrical insulation, ease of manufacture and cost of manufacture. However, if the security element is sealed by such a plastic material, it can be difficult for the security element to react sensitively to the change in the temperature of the battery cell. On the other hand, it is possible that the security element reacts more sensitively to the security element through the opening structure, as described above. As a result, it is possible to further improve the safety of the battery pack. In addition, it is possible to minimize the installation height of the PCM due to the installation of the security element, thus contributing to the increase in battery capacity. The shape of the external input and output terminal is not particularly restricted, as long as the external input and output terminal can be electrically connected to the PCB to supply current from an external device, such as a charger, to the battery cell or to supply current from the battery cell to a mobile phone, an mp3 player, etc. It is preferred that the external input and output terminal be configured in the form of a wire that has a connector mounted on one end of it.
    In another preferred example, a nickel plate can be additionally mounted on one side of the cathode terminal, which is coupled to the terminal connection part of the whole tube, by means of ultrasonic welding. Consequently, it is possible to avoid unsatisfactory welding due to the difference in properties between the cathode terminal, which is made of aluminum, and nickel.
    However, the first housing and / or the second housing may include holes, through which the electrodes of the battery cell are inserted, and a hole, through which the external input and output terminal extends outwards. In this structure, it is possible to achieve the electrical connection in the insulating mounting elements, while ensuring insulation from the outside.
    Consequently, the PCB and the security element can be easily coupled to each other in an assembly-style manner using the first housing and the second housing, excluding the electrode terminals of the battery cell and the external input and output terminal that extends through the holes.
    However, a label can be attached to the PCM excluding the external input and output terminal and side and outer sides of the battery cell to cover the PCM and the side and outer sides of the battery cell. Consequently, it is possible to ensure the electrical connection between the electrode terminals of the battery cell and the PCB more stable, while maintaining an isolated state without the use of an additional insulation tape.
    In a preferred example, the label can be configured to have a sheet structure comprising a first attachment surface to cover a larger surface of the battery cell, second and third attachment surface extending from the first attachment surface to cover the opposite side surfaces of the battery cell, and a fourth fixation surface that extends from the first fixation surface to cover the PCM. It is possible that the label has a single sheet structure to effectively cover only the necessary parts of the battery cell and to greatly improve the efficiency of the manufacturing process.
    In accordance with another aspect of the present invention, a protection circuit module of a specific structure is provided which is used to constitute the secondary battery pack with the construction mentioned above.
    Specifically, a protection circuit module (PCM) is provided to be mounted on top of the plate-shaped battery cell that has electrode terminals made of plate-shaped conductive elements formed at an upper end of the same, where the PCM includes a printed circuit board (PCB) that has a protection circuit formed on it, an external input and output terminal electrically connected to the protection circuit of the PCB, the PCB being provided on one side of it with a cathode terminal connection part and a security element connection part and on the other side of it an external input and output terminal connection part, and a first housing and a second housing coupled to each other via a mounting type fixing structure to cover the PCB and the security element.
    In a general process of assembling a battery pack, a connecting element and an F-PCM are coupled and an insulating tape is attached at each step, so that a PCM assembly is mounted on a battery cell. That is, the PCM assembly is mounted on the battery cell using a large number of parts. Consequently, a large number of processes are required. In addition, the mechanical strength and structural stability of the battery pack are low.
    On the other hand, the protection circuit module according to the present invention is configured to have a structure in which the security element is connected to the PCM and coupled to the first enclosure and the second enclosure in a state in which the security element is welded to the anode terminal. As a result, the mechanical strength of the battery pack is very high and the battery pack manufacturing process is greatly simplified.
    In a preferred example, the security element can be configured to have a structure in which one end of the security element is connected to the connection part of the security element in a state in which the other end of the security element is connected to the terminal of the battery cell anode.
    In addition, the cathode terminal connection part and the safety element connection part can be configured so that one end of the cathode terminal connection part and one end of the safety element connection part are perpendicularly curved , while the other end of the cathode terminal connection part and the other end of the safety element connection part are coupled to a rear side of the PCB. The first housing and / or the second housing can be configured to have a structure that includes holes, through which the electrodes of the battery cell are inserted, and a hole, through which the external input and output terminal extends out. The first enclosure can be provided with at least one fixing hole (or fixation protrusion), through which the first enclosure is coupled to the second enclosure, and the second enclosure can be provided with at least one fixation protrusion (or fixing) that corresponds to the fixing orifice (or fixation protrusion) of the first housing. In addition, at least one fixing hole and at least one fixing protrusion that corresponds to at least one fixing hole are preferably formed on the outer circumferential sides of the first and second casings that face each other. another to improve the clamping force and sealing force.
    It is preferred that the first housing or the second housing can be provided with an opening, through which the security element located in the PCM is exposed to the outside.
    In accordance with a further aspect of the present invention, a method of manufacturing method of the secondary battery pack with the construction mentioned above is provided.
    Specifically, the secondary battery pack according to the present invention can be manufactured using a method of manufacturing a secondary battery pack that includes (a) connecting an external wire-type input and output terminal to a connection part of external input and output terminal formed on a front side of a PCB, (b) connect a nickel plate to a rear side of a cathode terminal of a battery cell by means of ultrasonic welding, (c) connecting one end of a security element to a security element connecting part formed on a rear side of the PCB, in a state in which the other end of the security element is connected to a rear side of a cathode cell terminal battery, and connect the cathode terminal to a cathode terminal connection part, (d) couple a first housing and a second housing, so that the external input and output terminal extends a outwards in a state in which a PCM is arranged so that the connecting parts are arranged in parallel with the battery cell, thereby assembling the PCM, and (e) bending the electrode terminals of the battery cell and assembling the PCM in an excessively thermally welded part of the battery cell.
    As compared to a conventional secondary battery pack manufacturing method, the secondary battery pack manufacturing method according to the present invention can reduce the number of manufacturing processes and provide a battery pack that exhibits high mechanical strength and improved structural stability.
    In addition, the secondary battery pack manufacturing method according to the present invention may additionally include attaching a label to the PCM and side and outer sides of the battery cell, so that the label covers the PCM, excluding the external input and output terminal and the side faces and external sides of the battery cell, if necessary.
    Advantageous effects As is evident from the above description, the secondary battery pack according to the present invention is configured to have a new structure in which the PCM, which includes the first housing and the second housing, is loaded on the excess part thermally welded from the battery cell. Consequently, the manufacturing process of the secondary battery pack is simplified and the structural stability of the secondary battery pack is improved.
    Brief description of the drawings The objectives, characteristics and advantages above and others of the present invention will be understood more clearly from the following detailed description taken in conjunction with the attached drawings, in which: Figure 1 is a partial perspective view of a battery cell; Figure 2 is a partial perspective view showing a security element coupled to the battery cell; Figure 3 is a partial perspective view showing an external input and output terminal coupled to a printed circuit board (PCB); Figure 4 is a partial perspective view showing the PCB and the security element coupled to the upper end of the battery cell; Figure 5 is a partial perspective view showing the PCB and the security element of Figure 4 mounted in a second housing; Figure 6 is a partial perspective view showing the PCB and the security element of Figure 4 mounted on the first and second shells; Figure 7 is a typical view showing a process for charging a protection circuit module (PCM) of Figure 6 into a thermally welded surplus portion of the battery cell; and Figures 8 to 10 are typical views showing a process for attaching a label.
    Detailed description of the invention The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted, however, that the scope of the present invention is not limited by the illustrated modalities. Figure 1 is a partial perspective view of a battery cell, Figure 2 is a partial perspective view showing a security element coupled to the battery cell, Figure 3 is a partial perspective view showing a battery terminal external input and output coupled to a printed circuit board (PCB) and Figure 4 is a partial perspective view that typically shows the PCB and the security element attached to the upper end of the battery cell.
    With reference to these drawings, a battery cell 10 consists of a plate-shaped battery cell having an anode terminal 12 and a cathode terminal 11 formed at one end thereof. An electrode assembly of a cathode / separator / anode structure is mounted in a battery casing 18 made of a laminated sheet that includes a layer of metal and a layer of resin in a sealed state. Reference number 13 indicates a surplus thermally welded part, which consists of an upper end sealed part formed when the battery case 18 is thermally welded in a sealed state.
    A nickel plate 15 is additionally mounted on one side of the tube terminal 11 of the battery cell 10, which is coupled to a cathode terminal connection part 101, by means of ultrasonic welding.
    On the other hand, an external wire-type input and output terminal 110 that has a connector 111 mounted on one end of it is connected to one side of a PCB 100 and the cathode terminal connection part 101, which is made of a nickel plate, and a security element connection part 102, which is made of a nickel plate, are formed on the other side of PCB 100, so that the cathode terminal connection part 101 and the connecting part of security element 102 corresponds to cathode terminal 11 and a security element 120, respectively.
    As shown in Figure 4, one end of the connecting part 101 and one end of the connecting part 102 are perpendicularly curved, while the other end of the connecting part 101 and the other end of the connecting part 102 are coupled to the rear side of the PCB 100. Consequently, the connection parts 101 and 102 can be easily soldered to the cathode terminal 11 and the safety element 120, respectively. Security element 120 may consist of a positive temperature coefficient (PTC) element. Figure 5 is a partial perspective view showing the PCB and the security element of Figure 4 mounted on a second housing, Figure 6 is a partial perspective view showing the PCB and the security element of Figure 4 mounted on the first and second shells, and Figure 7 is a typical view showing a process for charging a PCM (protection circuit module) of Figure 6 over the thermally welded surplus portion of the battery cell.
    With reference to these drawings, a first housing 200 and a second housing 210 are coupled to cover PCB 100 and security element 120. The second housing 210 includes holes 211 and 212, through which electrode terminals 11 and 12 of the battery cell are inserted, and an orifice 213, through which the external input and output terminal 110 extends outward.
    In addition, the first housing 210 is provided with an opening 201, through which the security element 120 is exposed to the outside. Consequently, the installation of the first housing 210 does not cause the increase in overall height and it is possible that the safety element 120 reacts sensitively to the temperature change of the battery cell 10, although the safety element 120 is covered by the first housing 200 and the second housing 210.
    Therefore, in a state in which the electrode terminals 11 and 12 of the battery cell are inserted through the corresponding holes 211 and 212, the external input and output terminal 110 extends outwardly through the hole 213, and the safety element 120 is exposed through opening 201, the PCB 100 and the security element 120 are mounted between the first housing 200 and the second housing 210 to form a PCM 300. The first housing 200 and the second housing 210 are configured to have a structure mounting type fastening, by means of which the first housing 200 and the second housing 210 are coupled to each other.
    Specifically, the mounting type fixation structure consists of fixing protrusions 214, 215, 216, 217 and 218 (some of which are not shown) formed on the outer circumferential side in the vertical direction of the second housing 210 and fixing holes 204, 205, 206, 207 and 208 (some of which are not shown) formed on the outer circumferential side in the vertical direction of the first housing 200, so that the fixing holes 204, 205, 206, 207 and 208 correspond to the protrusions of fixation 214, 215, 216, 217 and 218 (some are not shown).
    After the PCB 100 and the security element 120 are mounted on the second housing 210, therefore, the assembly of the first housing 200 and the second housing 210 is achieved by coupling the clamping protrusions 214, 215, 216, 217 and 218 (some are not shown) and the fixing holes 204, 205, 206, 207 and 208 without using additional elements.
    In addition, PCM 300, in which PCB 100 and security element 120 are mounted between the first housing 200 and the second housing 210, is loaded onto the thermally welded surplus 13 of the battery cell 10. As compared to a conventional secondary battery pack, therefore, the durability and moisture resistance of the secondary battery pack according to the present invention are considerably improved, thus effectively protecting the PCM, considerably reducing the number of parts and improving manufacturing processability.
    Figures 8 to 10 are views that typically show a process for attaching a label 400 to the manufactured battery cell as shown in Figure 7.
    With reference to these drawings, the label 400 is configured to have a sheet structure that includes a first attachment surface 410 to cover a larger surface of the battery cell 10, second and third attachment surfaces 420 and 430 extending from the first attachment surface 410 to cover the opposite side surfaces of the battery cell 10, and a fourth attachment surface 440 which extends from the first attachment surface 410 to cover the PCM 300.
    Consequently, a larger surface of the battery cell 10 is positioned on the first fixing surface 410, the second and third fixing surfaces 420 and 430 are curved and fixed to the opposite side surfaces of the battery cell 10, so that the second and the third attachment surface 420 and 430 cover the opposite side surfaces of the battery cell 10, and the fourth attachment surface 440 is curved so that the fourth attachment surface 440 covers the PCM. In this way, the label 400 is attached to the battery cell 10. The label 400, which displays product information, more securely ensures the electrical connection between the electrode terminals of the battery cell and a PCB, while maintaining a isolated state on the opposite side faces as well as on the outside of the battery cell 10.
    Although the exemplary embodiments of the present invention have been presented for illustrative purposes, those skilled in the art will note that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention, as presented in the appended claims.
