【表】[Detailed Description of the Invention] [Industrial Field of Application] The present invention is used as a power source for portable electronic devices that are oriented toward miniaturization and thinning.In particular, the present invention will attract attention as a power source for IC cards, etc., which will replace magnetic cards. ing. Since IC cards are standardized to have a thickness of 0.76 mm, the thickness of the battery needs to be 0.5 mm or less. Furthermore, it has high energy and long-term reliability, and the IC circuit as shown in Figure 2. It is necessary to establish reliable and highly reliable electrical leads to the electrodes on the circuit board, and Figure 2a shows an example of a plug-in type as an electrode for an IC circuit board, and Figure 2b shows an example of a soldering type. As described above, flat plate batteries are required to have lead terminals. However, since the terminal plates of ultra-thin flat plate batteries are made of foil with a thickness of 20 to 30 μm, laser welding or electric resistance welding is used to attach the lead terminals to the battery, as is the case with coin batteries. Therefore, an ultra-thin flat plate battery with an integrated electrical lead terminal is required. The present invention relates to a manufacturing method for obtaining this ultra-thin flat plate battery with lead terminals. [Summary of the Invention] This invention prevents electrical contact between positive and negative electrodes, so-called shorting, in the manufacturing process of lead terminal parts in the manufacturing process of flat plate lithium batteries with lead terminals used in IC cards, etc. In addition, protruding lead terminals are easily damaged during manufacturing, which poses a problem in improving workability, so the length and width of the completed battery, including the protruding electrode lead terminals, are also more important during the sealing process (heat sealing). The terminal board is processed in advance to a size larger than the amount of protrusion of the sealing material, and this terminal board outer diameter is used as a guide in each process, and in the final process, unnecessary parts of the peripheral edges are punched out to integrate with the electrode terminal board. This is a method for manufacturing a flat plate type lithium battery having a lead terminal portion that protrudes beyond the outer diameter of the battery. [Prior art] Conventionally, flat plate batteries with lead terminals
As shown in Figures a and b, it was formed so as to be exposed from the inside of the battery to the sealing part. For example, public use in Showa 58-
Shown in 173164. On the other hand, as sealing materials and sealing technology have advanced, highly reliable flat-plate lithium batteries that integrate an exterior terminal plate that also serves as a current collector and a lead terminal plate are now mainstream, as shown in Figure 1 a and b. It became. This battery manufacturing method involves manufacturing and assembling the battery using positive and negative electrode terminal plates punched in advance to the dimensions and shape of the completed battery. [Problems to be Solved by the Invention] However, when manufacturing and assembling based on a protruding lead terminal plate, inserting the necessary power generation element into the protruding lead terminal plate and placing the terminal plate of the other pole will cause some problems. The position of the lead terminal may be misaligned, causing it to shoot between the electrode terminal plates, or the protruding lead terminal may be weak.
Easily damaged during the manufacturing process. On the other hand, when the electrode terminal plate and the sealing material are heat-sealed in the final step, the sealing material protrudes beyond the outer diameter of the electrode terminal plate, resulting in a defective outer diameter, which requires a step to remove the protruding portion. However, this process is not suitable for mass-production manufacturing processes because the sealing material protrudes, making positioning complicated and requiring special jigs to remove the protruding portion of the sealing material. Furthermore, as a product, misalignment in the combination of the positive and negative terminal plates directly results in misalignment of the protruding lead terminal portions, resulting in a drawback that the yield of the product is reduced. Therefore, the object of the present invention is to provide a manufacturing method that eliminates these conventional drawbacks. [Means for Solving the Problems] In order to solve the above problems, the present invention includes an electrode lead terminal portion that protrudes from an electrode terminal plate (in the example of the present invention, a positive electrode terminal plate) having a large outer diameter shape. An electrode terminal plate was used that had been processed in advance to have terminal plate dimensions larger than the external dimensions of the battery and the amount of protrusion of the sealing material during the sealing process. If one terminal plate (the negative terminal plate in the present invention) has a protruding electrode lead terminal, it is possible to create a shape in which a relief (missing part) is provided in advance at that location on the periphery of the opposing terminal plate. This is a manufacturing method that can prevent the above drawbacks. [Function] By manufacturing using electrode terminal boards with the dimensions and shapes described above, (1) If one terminal board has a protruding electrode lead terminal, the area around the opposing terminal board can be A relief is provided in advance to prevent shortcuts. (2) Because the protruding electrode lead terminal is protected by the defective part of the opposing terminal board due to the reason (1) above,
The protruding electrode lead terminal portion is prevented from being damaged during the manufacturing process. (3) Since the dimensions and shape of one terminal board are larger than the amount of sealing material that protrudes during heat sealing in the final assembly process, it is possible to prevent the sealing material from protruding more than the terminal board dimensions during heat sealing, and manufacturing It has become easier to guide during the process, and in particular the complicated process of punching out unnecessary parts around the battery after heat sealing has been simplified, and at the same time, the amount of misalignment of the protruding lead terminals has been halved. [Example] Examples of the present invention will be described below based on the drawings. In FIG. 1b, a lithium sheet 2, which is a negative electrode active material, is pressure-bonded to a negative electrode terminal plate 1, and a separator 3, which is an electrically insulating sheet, is placed thereon. Next, the positive electrode active material which is the positive electrode mixture 4, e.g.
MnO 2 is kneaded with an organic binder and a conductive material such as Gr, and the sheet is dried at high temperature.The sheet is cut into predetermined sizes and placed on a separator, and an electrolyte is injected into the sheet. Next, the positive electrode terminal plate 5 is placed through a sealing material 6, which is a film made of a polymeric resin material that is shaped into a square shape and has electrical insulation properties and has heat adhesive properties with metals. The material and the positive and negative terminal plates are heated under pressure and bonded together, so-called a heat sheet, to form a completed battery. Here, the negative terminal plate is a protrusion 10 which becomes a lead terminal as shown in FIG. 4a.
The positive terminal is designed to have the defective part 11 shown in Fig. 4b, and the protruding part and the defective part are not brought into contact as shown in Fig. 4c. , can be combined using a jig. Furthermore, by designing the protruding portion to be set on the same plane as the positive electrode terminal plate or slightly inside the same plane, damage to the electrical shoot and the lead terminal portion during the process is prevented. After heat-sealing, this integrated semi-finished battery is set in the guide of a punching die, and the unnecessary peripheral part of the electrode terminal plate is formed with the punching die to form an electrode lead terminal in a predetermined shape as shown in Figure 1a. Part 12 is formed and completed. The dimensions of the positive electrode terminal plate are designed to be larger than the amount of protrusion of the sealing material after heat sealing, so that the guide for the punching die can be easily removed. In addition, as other examples, Fig. 5 shows a case where a lead terminal part is provided only on the positive terminal plate, and Fig. 6 shows a case where a lead terminal part is provided only on the negative terminal plate, and as other application examples, various shapes are shown. is possible. [Effects of the Invention] As explained above, the present invention combines electrode terminal plates processed into a predetermined size and shape, and after heat-sealing, the unnecessary periphery of the electrode terminal plate is formed using a punching die, thereby forming a predetermined shape. A flat plate battery with lead terminals having the shape of can be stably manufactured for the following reasons. (1) Since one of the positive and negative electrodes has a relief part (defective part) for the other lead terminal part in advance, (a) prevention of electrical shoots during the process of machining the positive and negative lead terminal parts, and (b) ease of machining the lead terminals. Preventing damage during the process (2) Since the battery guide is securely secured during the processing process, flat batteries with lead terminals of any shape can be manufactured. On the other hand, the reason for providing a step of length l on the positive and negative terminal boards as shown in Figure 1 is to prevent shortening when the peripheral edge of the battery comes into contact with something that has electrical lead properties. The following is possible: In addition, in the finishing process, a die was used to punch out the positive electrode lead terminal portion, so the variation in the distance between the positive and negative electrode lead terminals was reduced to 1/2 as shown in Table 1. 【table】
