５ｍｍ以下の構造のものが知られている。By the way, as for the above-mentioned flat batteries, a power generation unit is conventionally made by laminating in this order a positive electrode mixture sheet consisting of a positive electrode active material, a conductive material, and a binder, a separator, and a negative electrode sheet consisting of metallic lithium. surrounded by a frame-shaped insulating sealing body made of modified polyethylene, modified polypropylene, or ionomer resin, and one frame-shaped surface of the positive electrode mixture sheet and the insulating sealing body has a thickness of 0.0.
A positive electrode terminal plate made of an annealed stainless steel plate or an annealed nickel plate with a thickness of 2 to 0.05 mm is tightly attached to cover them, and a thickness of 0.02 to 0.0 mm is attached to the other frame-shaped surface of the negative electrode sheet and the insulating sealing body. The power generation unit was sealed with a negative terminal plate made of a 0.05 mm annealed stainless steel plate or an annealed nickel plate so as to cover them.

た。[Problems to be Solved by the Invention] However, in the flat lithium battery described above, the positive and negative electrode terminal plates are made of thin and annealed soft metal such as an annealed stainless steel plate or an annealed nickel plate with a thickness of 0.02 to 0.05 a + JII. Since plates are used, there is a problem in that the positive and negative terminal plates are damaged by dents, scratches, etc. during battery manufacturing, which significantly reduces the product value. In addition, during use, the positive and negative terminal plates are easily susceptible to external damage; for example, if a sharp object collides with the terminal plate, a hole will be created in the terminal plate and the electrolyte will leak from there, significantly reducing the performance and reliability of the battery. There was a problem with deterioration.

The electrolyte leaks through the holes, which significantly deteriorates the battery's performance and reliability.

The aim is to provide a highly reliable flat battery that can withstand even severe usage conditions.

ケルメッキ膜のビッカース硬度は、７００以上である。The composite electroless nickel plating film in which fine ceramic powder or fine metal powder is dispersed is coated on the stainless steel sheet, for example, by electroless plating the stainless steel sheet in an electroless nickel plating bath containing fine ceramic powder or fine metal powder. At the same time, the ceramic fine powder or the like can be precipitated and dispersed in the plating film to form the plating film. The hardness of the composite electroless nickel plating film thus formed can be adjusted by adjusting the properties (mainly hardness) and amount of dispersed ceramic fine powder or metal powder, but it is usually desirable to have a Vickers hardness of 500 or more. . The reason for this is that if the Vickers hardness of the composite electroless nickel plating film is less than 500, sufficient hardness cannot be imparted to the terminal board, and dents and scratches are likely to occur during manufacturing and use, resulting in poor appearance. This is because, under severe operating conditions such as when a large load is concentrated on one point, holes may form in the terminal board, resulting in a significant decrease in reliability. More preferable composite electroless Ml? The Vickers hardness of the nickel plating film is 700 or more.

It is desirable to set it in the range of 01 to 0.03 mm.

ため、集電性を向上できる。[Function] According to the present invention, at least one of the positive and negative terminal plates has a robust structure in which a stainless steel plate is coated with a composite electroless nickel plating film in which fine ceramic powder or fine metal powder is dispersed. It is difficult to receive external damage such as dents and scratches during use, and maintains a good appearance, even under harsh usage conditions where large loads are concentrated on one point due to sharp edges. It is possible to obtain a highly reliable flat battery that prevents accidents such as electrolyte leakage by avoiding holes and the like. Moreover, by making the terminal plate have a robust structure, it is possible to suppress the curvature of the terminal plate, and it is possible to improve the tightness of the tube with respect to the positive electrode mixture sheet and the negative electrode sheet, so that the current collection property can be improved.

。Comparative Examples 1 to 3 Three types of flat batteries were manufactured in the same manner as in Example 1, except that the positive and negative electrode terminal plates were formed from 5US304 steel plates having thicknesses of o and o5 mm and a Vickers hardness of 200.300.400.

観不良が見られた。Thus, 500 flat batteries of Examples 1 to 3 and Comparative Examples 1 to 3 were each produced, and the presence or absence of dents and scratches on the terminal boards after production was examined. The results were 10% in Comparative Example 1 (using a terminal plate with a Vickers hardness of 200), 4% in Comparative Example 2 (using a terminal plate with a Vickers hardness of 300), and Comparative Example 3.
(Using a terminal board with a Vickers hardness of 400), 2% of appearance defects were observed.
これに対し、本実施例１〜３の電池では端子板に商品価
値を損うような打痕、傷による外観不良は皆無であった
。In contrast, in the batteries of Examples 1 to 3, there were no appearance defects such as dents or scratches on the terminal boards that would impair commercial value.

ことが確認された。Further, a load of 3 kg was applied to the center of the flat batteries of Examples 1 to 3 and Comparative Examples 1 to 3 using a cylindrical rod with a diameter of 0.5 mm, and then the discharge characteristics were examined. As a result, in all of the flat batteries of Comparative Examples 1 to 3, holes were formed in the terminal plates, leaking of the electrolyte occurred, and the batteries did not operate as batteries. On the other hand, in the batteries of Examples 1 to 3, no holes were formed in the terminal plates, and it was confirmed that the batteries had good discharge characteristics.

な高信頼性、高品質の扁平形電池を提供できる。[Effects of the Invention] As detailed above, according to the present invention, it is difficult to receive external damage such as dents and scratches during manufacturing and use, and it is possible to maintain good appearance. Even under harsh usage conditions where the power is concentrated at one point, it is possible to avoid punctures in the terminal board, prevent accidents such as leakage of electrolyte, and further improve current collection, which in turn improves card-type electronic equipment. It is possible to provide a highly reliable and high quality flat battery suitable as a power source.
