Description

  In the present invention, history information necessary for performing at least one traceability from manufacturing to disposal of a battery such as a primary battery represented by a dry battery or a secondary battery represented by a lithium ion battery is stored in an IC tag. It is related to the battery.

  Traditionally, the primary purpose of managing the battery manufacturing process is to provide information on suppliers and consumers, such as whether appropriate raw materials and parts are used, or whether packaging and storage conditions in the manufacturing process were appropriate To meet your needs. In other words, in order to manufacture the battery, it is traced along the flow from manufacturing to storage such as when, where, what kind of raw materials and parts are used, what kind of manufacturing process, packing process, storage process, etc. It is to perform trace forward. In addition, what route is sold and used by consumers, under what circumstances the device is installed and used, and in what state the used battery is discarded It is to perform trace forward from manufacturing to disposal by having a lot of information.

  In addition, the second purpose of managing the battery manufacturing process is to determine which raw materials and parts were used for the product in which a problem occurred when a problem occurred at the supplier or consumer, It is to strengthen the risk management of battery manufacturers such as where and where it is now. In other words, the battery is traced back from production to storage, such as when, where, what raw materials and parts are used, and what kind of manufacturing process is used to manufacture, package, and store. is there. Furthermore, trace back from manufacture to disposal of a discarded battery is performed by having information from manufacture to disposal as in the trace forward.

  In the manufacturing process of the primary battery, there are roughly four pieces of manufacturing history information given to the battery. The first is the product type, the second is the date of manufacture, the third is the name of the manufactured product, and the fourth is for logistics and sales. Information on varieties, recommended expiration dates, and prices. These methods of providing information include labels and color-sensitive prints that identify varieties and heat-sensitive shrink films, ink-jet printing such as characters, symbols, and barcodes, or laser printing, and heat-sensitive printing information. In general, adhesive shrink films and stickers are attached, and the information is printed on plastic packs or outer packaging.

  On the other hand, in the manufacturing process of secondary batteries, the raw material lot number, delivery date and time, historical information about raw materials such as delivery inspection item data, raw material weighing data, equipment used, historical information about measuring raw materials such as work time, raw material History information about raw material input such as input time, worker, work condition, input line number, part lot number, delivery date / time, part history information such as delivery inspection item data, battery component material lot number, input time, work In general, the history information regarding the construction status of the battery constituent materials such as the operator, work conditions, and input line number is recorded as a record in each process by a control chart or daily work report.

  In addition to document management based on records such as control charts or daily work reports, as a means for more efficient process management, barcodes, etc. are widely used in all daily goods and foods. It is common practice to apply a label.

Furthermore, in a secondary battery, a method of printing or sticking a production lot number and defective item data is disclosed as means for collecting production history information. (For example, see Patent Document 1)
JP 2002-184464 A

  However, in the method of printing characters, symbols, etc. of the prior art of Patent Document 1 described above, there is a limit to the amount of information that can be given to the battery due to the size and design of the battery, so that the traceability of the manufacturing process is performed. Was insufficient. Specifically, for example, in the case of a dry battery, the recommended use time limit display is substituted for the manufacturing time information of each battery, and the information given is monthly. If a trouble occurs in the manufacturing process and a defect due to the trouble is discovered by a sampling inspection in the subsequent process, it is not possible to properly narrow down the batteries that are suspected of being defective. It was. In addition, it is difficult to obtain a lot of information such as a sales route after shipment, devices used, and usage information, and it is impossible to grasp each battery.

  In addition, in the case of batteries with a large production volume, inventory confirmation of finished products, work in progress, and materials is weekly or monthly management, and it is difficult to grasp product inventory in real time. The method of pasting labels such as barcodes as a means of collecting battery history information is more distinctive than character recognition, but the maximum data capacity that can be stored in barcodes is small, aging In addition, there are problems such as low durability against dirt and easy illegal copying.

  In addition, in order to collect history information using bar codes, the user must actively read each one by holding the reader over or through the reader, and the maximum communication distance is 50 cm. Since it is before and after, the usable range is naturally narrowed. For this reason, there is an automatic reading system using a bar code, but it is necessary to introduce a very expensive and large-scale device in order to realize bar code positioning and recognition.

  In addition, the used battery is discarded, but some materials used in the battery can be reused, and there are some environmental issues that should be handled with care for disposal. In that case, it is necessary to first collect the battery, and the collected battery can be disassembled and the material used in the battery can be grasped at the time of disassembly so that the response can be performed quickly. Obtaining historical information on the materials used in the battery makes it easier to take environmental measures against disposal. Reusable materials can be reused for recycling and effective use of resources.

  The present invention has been made in view of the above-described conventional problems, and traces that track history information along the battery manufacturing process, packing process, storage process, sales process, use process, charging process, reuse process, and disposal process. By efficiently performing both forward and traceback that traces back the history information of battery manufacturing process, packing process, storage process, sales process, use process, charging process, reuse process, and disposal process. An object of the present invention is to provide a battery capable of battery traceability.

  In order to achieve the above-described object, the battery of the present invention includes an IC tag storing history information necessary for performing at least one traceability from manufacture to disposal. It is an object of the present invention to provide a battery that can efficiently perform both trace forward and trace back.

  According to the present invention, each battery is provided with an IC tag storing history information necessary for performing at least one traceability from battery manufacture to disposal, thereby realizing individual battery traceability. History information from battery manufacture to disposal can be efficiently collected. In addition to being able to collect information on battery inventory in real time, history information of individual batteries can be attached to the battery itself, so the manufacturing process, packing process, storage process, sales process, use process, charging process, and reuse Although it is not necessary to store enormous information in the process and disposal process, it is possible to take measures such as trouble and quality improvement based on the history information of individual batteries.

  The first invention of the present invention includes an IC tag storing history information necessary for performing at least one traceability from disposal to use of a battery, so that the amount of information can be dramatically increased and efficient. History information can be collected, and by grasping the history information, it is possible to investigate at which point of the process the cause of the trouble has occurred. In spite of not storing, measures corresponding to individual batteries are possible.

  According to a second aspect of the present invention, at least one history information from manufacturing to disposal is a manufacturing process, a packing process, a storage process, a sales process, a use process, a charging process, a reuse process, and a disposal process. Traceability can meet the information needs of suppliers and consumers, and the risk management of battery manufacturers can be strengthened for defective batteries.

  According to the third aspect of the present invention, since the ID number is given in the IC tag, the lot number, the delivery date and time, the delivery inspection item data, etc. of the raw materials in the manufacturing process can be distinguished. A battery that stores the history information of each process can be made compact, and the structure for storing the history information is not complicated, even though there are no restrictions on the position, orientation, etc. of the product to extract the identification history information. can do.

  According to a fourth aspect of the present invention, the history information and ID number of each battery from manufacture to use stored in an IC tag is encrypted, so that the history information for identifying individual batteries is obtained. A battery that can be transmitted as highly reliable and accurate information can be provided.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart showing the flow of traceability in one embodiment of the present invention. The battery 1 equipped with the IC tag 2 is manufactured in the manufacturing process 101, and detailed explanation will be given later. However, history information such as materials, manufacturing conditions, inspection results, etc. in each process of the assembly process and finishing process is transmitted via the wireless transmission / reception unit. It is stored in the IC tag 2 provided in the battery 1 by the information terminal. Next, in the packing process 102, the battery 1 manufactured in the manufacturing process 101 is packed in an outer box or the like. At this time, the quantity of the outer box, the number of the outer box, the date of packing, and the like are stored as history information in the IC tag 2 provided in the battery 1 by the information terminal via the wireless transmission / reception unit.

Next, in the storage step 103, the battery 1 packed in the packing step 102 is temporarily stored in a storage location of the factory, and is transported by truck to a distribution warehouse and stored as stock. In the distribution warehouse, the batteries 1 are stored until they are shipped according to the requested quantity at the date and time of the equipment manufacturer or each dealer. Further, in the storage process 103, the storage status of the battery 1 stored, the storage date such as the shipping temperature, the humidity temperature, the shipping destination dealer identification number or the device manufacturer identification number, etc. are transmitted via the wireless transmission / reception unit to the information terminal. Is stored as history information in the IC tag 2 provided in the battery 1. In addition, the history information such as the identification number, entry time, and delivery time of the incoming truck is stored in the IC tag 2 via the wireless transmitter / receiver installed in the storage process 103 that is primarily stored in the factory storage location. The history information corresponding to the ID number of the battery 1 was accumulated in the information terminal installed in the storage 103.

  Here, when the shipped battery 1 is defective or when it is determined that there is a risk of a defect caused by one of the processing machines in the manufacturing process, the battery 1 is stored in the IC tag 2 of the battery 1. By querying the memory, history information such as the production line name of the battery 1, the lot number of parts and raw materials, the processing machine identification number, and the passing time of each assembly process can be confirmed, and the cause of the failure can be specified. In addition, by referring to the ID number of the battery 1 at the information terminal in the storage process 103, the location and shipping destination of the corresponding battery 1 can be specified, and the battery 1 suspected of being defective can be quickly collected. Is possible.

  After storage, the battery 1 to be shipped is shipped to the consumer market or to a device manufacturer. In the consumer market, it is delivered to dealers and sold. The battery 1 delivered to the receiving warehouse of the store in the sales process 104 is sold in the IC tag 2 provided in the battery 1 in the sales process 104 by the information terminal through the wireless transmission / reception unit installed in the receiving warehouse. Stores historical information such as region, delivery date, sales date, and price.

  In the sales process 104, the history information of the battery 1 is collected, and it can be verified whether the battery is manufactured by an authorized manufacturer and delivered by an authorized route. In recent years, many high-priced batteries 1 typified by secondary batteries are imitated and sold at low prices. These imitation batteries not only reduce sales of genuine products, they are also dangerous for consumers who use imitation batteries that are not safe enough, and defects are generated from counterfeit batteries that consumers purchase as genuine batteries In this case, it may lead to the loss of trust of the authorized battery manufacturer. It is also possible to prevent the counterfeit battery from being sold to consumers by collecting and collating history information in the IC tag 2.

  In addition, the store in the sales process 104 can grasp at any time the presence or absence of the battery 1 displayed on the sales display shelf, and it is out of stock by placing an order at the distribution warehouse according to the sales, and has a large amount of inventory. I can not. In addition, since battery manufacturers are expected to produce products with the demands of dealers in advance, it is necessary to always have a large amount of inventory so that they can respond to changes in the quantity requested by dealers. Does not necessarily match the number of purchases by the buyer. For this reason, for example, when the demand rapidly decreases in the consumer market, the battery manufacturer may have a large amount of inventory. In the sales process 104, the sales at the store can be grasped in real time, and it is possible to respond quickly to changes in demand, and it is possible to reduce costs by reducing inventory.

  In addition, an alarm or the like is issued by storing and checking as history information in the IC tag 2 provided in the battery 1 whether the payment is completed or not at the checkout office of the sales process 104. It can also be used for crime prevention measures to prevent the unpaid battery 1 from being taken out of the store.

Next, the battery 1 shipped to the device manufacturer from the storage step 103 is attached to the device in the set manufacturer step 105. Also in the set maker process 105, counterfeit goods measures are possible by collecting the history information stored in the IC tag 2 provided in the battery 1. In addition, the IC tag 2 provided in the battery 1 by the information terminal via the wireless transmission / reception unit, such as the number of the device in which the battery 1 is attached, the installation date, the storage status, the power supply information to the device, the number of sets to the device, etc. Stored as data. Here, when a malfunction occurs when the battery 1 is mounted on a device, it is possible to immediately determine which process has been performed by collecting history information in the IC tag 2 provided in the battery 1, By checking with the battery manufacturer, it is possible to grasp in real time whether the battery 1 is malfunctioning or the device is malfunctioning. The device to which the battery 1 is attached in the set maker process 105 is sold in the sales process 107 in the same manner as the sales process 104 for the consumer market described above. History information such as date is stored in the IC tag 2 provided in the battery 1.

  Further, the battery 1 sold in the sales processes 104 and 107 is consumed by the consumer. Although the performance of the device used may be limited, the history information of the usage status is stored as data such as continuous use time, use date and time, and lifetime in the IC tag 2 provided in the battery 1 by the device used. On the use device side, it is possible to give a warning of reverse mounting of the positive electrode and the negative electrode of the battery 1 or a warning of the imitation battery based on the history information. Further, in the battery 1 that can be charged, the charging process 108 and the reuse process 109 store history information such as the number of times of charging, the charging status, and the overdischarge status in the IC tag 2 provided in the battery 1 by the charger. The

  Finally, the used battery 1 is stored in the IC tag 2 provided in the battery 1 by the used device as the history information when it is removed from the used device, and is discarded in the disposal step 110.

  The discarded battery 1 is sent to the collecting step 121 through the discarding step 110. In the collection step 121, history information such as the usage status of the battery 1, the life time, the number of times of charging for the rechargeable battery 1 and the charging status is collected from the IC tag 2 provided in the battery 1, and information for trouble and quality improvement Can be used as In addition, some materials such as the electrolyte solution used for the battery 1 must be handled as hazardous materials, and there is an advantage that it is easy to take environmental measures by clarifying the handling of the materials to be discarded when discarded. Moreover, it becomes easy to separate for each component contained in the used material of the battery 1 decomposed in the decomposition step 122, and the reusable material is reused in the reuse step 123. In addition, materials that cannot be reused are discarded in the disposal step 124 in consideration of environmental problems.

  In addition to storing all the history information of each process as data in the IC tag 2 provided in each battery 1, more detailed data is organized and accumulated in the host computer as history information of each process, and the ID number Or, for example, the traceability of the battery 1 may be performed by tracing and tracing back more detailed data according to the production line name.

  A specific embodiment in which history information can be stored on the battery manufacturer side will be described below.

  Referring to a manufacturing process on the battery manufacturer side for a method for storing battery history information in the present invention, an example of a manufacturing process of a primary battery and a primary battery, and an example of a manufacturing process of a secondary battery The details will be explained with the exchange.

Here, from the information terminal 4 installed in the first step of the assembly step 11, the ID number of the battery 1 and the manufacturing line identification number corresponding to the ID number of the battery 1 via the wireless transmission / reception unit 3, It was stored as data in the IC tag 2 together with history information such as the lot number and process passage time.

  Here, the battery case 14 will be described as Example 1 of the history information. A battery case called a DI can is used as the battery case 14 and is produced by drawing and ironing a thin nickel-plated steel sheet using a press machine and a mold. The surface of the battery case 14 is scratched or cracked due to various causes such as a problem with the nickel-plated steel sheet used as the material of the battery case 14, poor maintenance of the press mold, lack of lubricating oil, and the like. When these defective products are supplied to the production process of the battery 1, the transport conveyor may be clogged due to the crack of the battery case 14, and it cannot be shipped due to scratches on the assembled battery 1 and is handled as a reserved product. Sex is reduced. In addition, when heavy defective products are shipped and sold in the market, there is a risk of accidents such as leakage of the electrolyte solution 17 from the battery case 14 during use, which lowers the reputation in the market and causes significant loss as a company. Invite.

  Therefore, the lot number of the nickel plated steel sheet used for the battery case 14 as history information, the manufacturing time, the lot number of the nickel plating solution, the new and old plating solution, the distribution amount of the plating solution, and the old and new used molds The state, the usage time of the lubricating oil, and the like are stored as data in the IC tag 2, and history information of each battery is given to each battery 1. Next, the battery case 14 is transported to the molding process, which is the second process of the assembly process 11, and the positive electrode mixture 15 molded on the ring is supplied to each battery case 14. Here, from the information terminal 4 installed in the second process of the assembly process 11, the ID number of the battery 1 and the lot number of the positive electrode mixture 15 corresponding to the ID number of the battery 1 and molding are formed via the wireless transmission / reception unit 3. It was stored as data in the IC tag 2 together with the processing machine identification number and history information of the process passage time.

  Next, the battery case 14 is transferred to a battery case grooving process which is a third process of the assembly process 11. Here, the ID number of the battery 1 and the grooving machine identification number corresponding to the ID number of the battery 1 and the grooving through the wireless transmission / reception unit 3 from the information terminal 4 installed in the third process of the assembly process 11 The IC tag 2 was stored as data together with history information such as the use conditions of the process and the process passing time.

Next, the battery case 14 is transported to the separator insertion step, which is the fourth step of the assembly step 11. Here, the ID number of the battery 1 and the material lot number of the separator 16 corresponding to the ID number of the battery 1 and the insertion of the separator via the wireless transmission / reception unit 3 from the information terminal 4 installed in the fourth process of the assembly process 11 IC with machine identification number and process transit time history information
Stored in tag 2 as data.

  Next, the battery case 14 is transported to the liquid injection process, which is the fifth process of the assembly process 11, and the electrolytic solution 17 is injected. Here, the ID number of the battery 1 and the material lot number of the electrolyte 17 corresponding to the ID number of the battery 1 from the information terminal 4 installed in the fifth process of the assembly process 11 via the wireless transmission / reception unit 3, It was stored as data in the IC tag 2 together with the liquid machine identification number and the history information of the process passage time.

  Next, the battery case 14 is transported to the negative electrode mixture injection step, which is the sixth step of the assembly step 11. Here, the ID number of the battery 1 and the material lot number of the negative electrode mixture 18 corresponding to the ID number of the battery 1 via the wireless transmission / reception unit 3 from the information terminal 4 installed in the sixth process of the assembly process 11, It was stored as data in the IC tag 2 together with the negative electrode composite material insertion machine identification number and the history information of the process passage time.

  Next, the battery case 14 is transported to the current collector insertion and caulking process, which is the seventh process of the assembly process 11. Here, the ID number of the battery 1 and the lot number of the current collector 19 corresponding to the ID number of the battery 1 from the information terminal 4 installed in the seventh step of the assembly process 11 and the caulking It was stored as data in the IC tag 2 together with the processing machine identification number and history information of the process passage time. The unit cells 20 assembled through the assembly step 11 are boxed, and after aging, are transported to the unit cell supply step which is the first step of the finishing step 12. Here, the ID number of the battery 1, the manufacturing line identification number corresponding to the battery ID number, and the history of the process passing time are transmitted from the information terminal 4 installed in the first process of the finishing process 12 via the wireless transmission / reception unit 3. It was stored as data in the IC tag 2 together with the information.

  Next, the unit cell 20 is transported to the product type identification label winding process which is the second process of the finishing process 12. Here, the ID number of the battery 1, the type identification number corresponding to the ID number of the battery 1, and the material lot of the label 21 through the wireless transmission / reception unit 3 from the information terminal 4 installed in the second process of the finishing process 12. It was stored as data in the IC tag 2 together with the history information of the number, label winding machine identification number, and process passage time.

  Next, it is transferred to an inspection process for selecting defects by inspecting / measuring the weight and voltage of the completed battery 1 as the third process of the finishing process 12. Here, the ID number of the battery 1 and the inspection machine identification number corresponding to the ID number of the battery 1, the inspection result, the process via the wireless transmission / reception unit 3 from the information terminal 4 installed in the third process of the finishing process 12 The data was stored as data in the IC tag 2 together with the passage time history information.

  FIG. 4 shows a schematic cross-sectional view of an alkaline battery including the IC tag 2 manufactured through the assembly process 11 and the finishing process 12 described above.

  When a defect occurs using the battery 1 manufactured in this way, the history information in the IC tag 2 provided in the battery 1 indicates the manufacturing line of the battery 1, the manufacturing time, and the processing machine in each process. The identification number and other information can be confirmed. Detailed information such as history information on raw materials and battery parts, history information on manufacturing processes, etc., which could not be provided until now, is also given to each battery 1 and trace forward. Alternatively, it is possible to take out history information necessary for performing traceback from the IC tag 2 and perform traceability of each battery 1.

  Further, since the history information of each battery 1 is given to each battery 1, access to the host computer 5 is not required when examining the history information. In addition, since it is not necessary to network information terminals in each process, the system can be constructed at low cost.

  As a form of shipment of the battery 1, when the assembly process 11 and the finishing process 12 are performed, the product is shipped to a device manufacturer or the like in a single product state, and further, after the packaging process 13, the heat-sensitive shrinkage is performed for one or a plurality of batteries. In some cases, the product is shipped to a device manufacturer or a consumer market in a state packed with a film 22 or the like. In the packaging process 13, a sticker 23 indicating the type, number, supplier name information, etc. is attached to the battery pack as necessary, and the package is shipped in the outer box 24 in units of tens or hundreds of packs. Moreover, it is mounted on a device in a device manufacturer in a single product state or in a plurality of states.

  FIG. 5 is a schematic view of the primary battery and the packaging process of the primary battery in Example 2. The battery 1 which passed through the assembly process 11 and the finishing process 12 of the battery 1 in the same manner as in Example 1 was supplied to the packaging process 13 as shown in FIG.

  The battery 1 packaged with this heat-sensitive shrink film 22 was conveyed to a process of attaching a seal 23 on which the type, number, supplier name and price were printed. Here, the seal 23 is printed with only the type and the quantity packaged with the heat-sensitive shrink film 22, and the type identification number, the quantity packaged with the heat-sensitive shrink film 22, the supplier name identification number, the price History information and the like are stored as additional data in the IC tag 2 from the information terminal 4 via the wireless transmission / reception unit 3.

  After pasting this seal 23 on the heat-sensitive shrink film 22, the history information stored in the IC tag 2 provided in the battery 1 is received from the wireless transmission / reception unit 3 installed in the film packaging process of the packaging process 13. It was possible to match the varieties of the battery 1 and the seal 23 and the quantity packaged with the heat-sensitive shrink film 22. When packaging the battery 1 with the heat-sensitive shrink film 22, different varieties may be mixed due to material supply errors, line troubles, or human factors. Conventionally, only when the information is given by the barcode on both the packaging in the battery 1 or the heat-sensitive shrink film 22 and the outer box 24, the both are aligned using the barcode reader before the packaging. However, it was not possible to reconcile items without barcodes. In addition, there was no method for inspecting the mixing of different varieties after packaging with the heat-sensitive shrink film 22.

  Furthermore, after the information application process, it is necessary to confirm whether the information has been securely applied to each battery. However, since the information is provided as visual information, it is necessary to check for dirt and the mutual positional relationship between the product and the inspection machine. It was necessary to keep in mind. Specifically, when the sticker 23 on which the barcode is printed is attached to the heat-sensitive shrinkable film 22, in the confirmation inspection process where the seal 23 is attached, not only the orientation and the attachment position of the barcode but also the scratches on the seal 23, The recognition rate of the barcode reader decreases due to dirt, faint printing, and fine wrinkles. Therefore, since the position, orientation, and distance of the product with respect to the barcode reader need to be carefully adjusted, it takes time to make adjustments at the time of switching in the multi-product production line, resulting in a decrease in the operating rate.

  Next, after packaging with the heat-sensitive shrink film 22, it is transported to the packaging box packaging process of the packaging process 13 and packed in the packaging box 24 in units of 400. Here, in the IC tag 2 provided in each battery 1, the product identification number, the packaging quantity and the supplier name, and the price history information on the heat-sensitive shrink film 22 were stored as data. The battery 1 packed in the outer box 24 is supplied from the wireless transmission / reception unit 3 installed in the outer box packing process of the packing process 13 with the product type identification number and the heat-sensitive shrinkage stored in the IC tag 2 provided in the battery 1. It is possible to match the history information of the packaging quantity and supplier name identification code on the film 22 with the product identification number displayed on the outer box 24 and the packaging quantity and supplier name identification code on the heat-sensitive shrink film 22. there were.

  Further, when the battery 1 is packaged with the heat-sensitive shrink film 22 and then packed in the outer box 24 or the like, there may be a shortage of the number of battery packs due to material supply errors, line troubles, or human factors. Conventionally, inspection by weight measurement has been made for this problem, but it has been difficult to grasp the exact battery quantity. In the present invention, the history information in the IC tag 2 provided in the battery 1 is collected by collecting the accurate quantity of the battery 1 packed in the outer box 24 and the quantity packed in the heat-sensitive shrink film 22. It became possible to grasp.

  FIG. 6 is a schematic view of a storage location for battery raw materials and parts in the third embodiment. As shown in FIG. 6, the pallet 41 is divided into lot units for the raw material of the battery 1 and the battery component 40, and the IC tag 42 is provided on the pallet 41. In the IC tag 42, history information in units of lots such as the types of raw materials and battery parts 40, manufacturing lot numbers, and pallet mounting quantities is stored as a memory.

  When the wireless transmission / reception unit 3 is installed in the storage location of these raw materials and battery parts 40 and the history information in the IC tag 42 is read, it is possible to check the types, manufacturing lot numbers, quantities, etc. of the raw materials and battery parts 40. there were. Further, history information of raw materials and battery parts 40 in units of lots is stored in the IC tag 2 provided in each battery 1 as additional data of the history information of the battery 1 in the assembly process 11, the finishing process 12, and the packaging process 13.

Separated.

  Here, with respect to the main constituent materials up to the group constituting step 52 for producing the electrode group 60, it is very difficult to obtain the history information for each product, so the history information for each lot was stored in the IC tag 2.

First, in the source process 51, a lot number is assigned for each lot for each of the positive electrode plate 56 and the negative electrode plate 57, and the positive electrode active material which is a main constituent material for the positive electrode plate 56 as history information other than the lot number. The material information such as the conductive material, the binder, and the current collector was stored as history information X in the IC tag 2 for each lot. For the negative electrode plate 57 as well, material information such as negative electrode active materials, binders, thickeners, and current collectors, which are main constituent materials, was stored as history information X in the IC tag 2 for each lot.
Next, in the group composition step 52, a lot number is assigned to each of the positive electrode plate 56, the negative electrode plate 57, and the separator 58, and as the history information other than the lot number, the input date and time when the group composition is performed, the operator, History information relating to the group configuration configuration conditions such as work conditions and input line numbers is stored as history information Y.
Next, in FIG. 8, in the assembling process 53, the IC tag 2 having the ID number assigned to the secondary battery 62 for inserting the electrode group 60 is provided, and at the wireless transmission / reception unit installed in the assembling process 53 By performing data communication, the history information X and the history information Y are stored in the IC tag 2 as data.

  The history information X and the history information Y stored in the IC tag 2 by this data communication are stored as data that has been encrypted simultaneously with simplification, and more detailed data is stored in the host computer where the assembly process is installed. It can also be stored as a database.

  Further, the history information of the electrolyte solution 59 used in the secondary battery 62 and other components 61 that are a plurality of main components is data-communicated by the wireless transmission / reception unit installed in the assembly process 53, thereby the secondary battery 62. The history information Z of the secondary battery 62 is stored as data in the IC tag 2 included in the.

  The history information Z stored in the IC tag 2 by this data communication is stored as data that is encrypted at the same time as simplification, and more detailed data is stored as a database in the host computer where the assembly process is installed. It was also possible to do.

  As a method of performing traceback of the manufacturing process of the secondary battery in the present invention, the history information of the secondary battery is stored in the IC tag retroactively using the IC tag provided in the secondary battery. The history information of the secondary battery was tracked.

  Specifically, as shown in FIG. 8, using the secondary battery 62 that has been subjected to the trace forward A in the same manner as in the fifth embodiment, the manufacturing process is traced back to the assembly process 53, the group composition process 52, the source process 51, and the like. Trace back B was performed by tracing in reverse.

First, using the ID number stored in the IC tag 2 of the secondary battery 62, the history information Z related to the secondary battery 62 was extracted. From this history information Z, it was possible to clarify information such as the electrolyte 59 used in the secondary battery 62, history information of a plurality of other main components, and manufacturing conditions of the assembly process 53.

Next, using this history information Z, history information Y related to the secondary battery 62 stored in the IC tag 2 of the secondary battery 62 was extracted. From this history information Y, history information such as the lot number of the positive electrode plate 56, the lot number of the negative electrode plate 57, the lot number of the separator 58, etc. used for the group configuration, and the date and time when the secondary battery electrode group was configured. It was possible to clarify detailed group composition conditions such as workers, work conditions, and input line numbers.
Further, using the history information Y, the history information X related to the secondary battery 62 stored in the IC tag 2 of the secondary battery 62 is extracted. From this history information X, positive electrode plate 56 and negative electrode plate 57, raw material weighing data when each electrode plate was created, history information about electrode plate manufacturing conditions such as equipment used, work date and time, worker, working conditions, In addition, information on raw materials of each electrode plate main constituent material, specifically information on raw materials such as raw material lot number, delivery date and time, delivery inspection item data, etc. could be clarified.
By collecting and grasping the history information of the battery 1 in the IC tag 2 by the battery 1 having the IC tag 2 storing the history information in this way, it becomes easy to manage the inventory of battery manufacturers, equipment manufacturers and dealers. Battery history information such as the number of times of charging can be displayed on the device, which can support the usage of consumers, and it can be used for counterfeit products and anti-theft measures at dealers. It can be widely used for environmental measures.
Furthermore, it is possible to appeal which process is the cause at the time of trouble, and responsibilities of battery manufacturers, equipment manufacturers, transporters, dealers, consumers, etc. become clear. In addition, although the specific example is not shown about the example of the historical information in a store, an apparatus maker, and a user side, it becomes realizable as mentioned above by the action by the battery maker side.
