本発明は、ボタン型電池の封口構造の改良に関し、高容
量で耐漏液性の良い電池を提供することを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the sealing structure of a button-type battery, and an object of the present invention is to provide a battery with high capacity and good leakage resistance.

電容量の向上は、部品形状を変え内容積が最大になる様
に考慮されている。図に、−例として空気・亜鉛ボタン

因は負極封口板３と３′の形状の差にある。すなわち、
第１図のものは封口板周辺部に折り曲げ部がなく、第２
図のものは周辺部に外側上方への折り曲げ部がある３゜
この形状差が、電池内容積に大小の差を与えている。Since primary batteries generally have limited outer diameter dimensions, improvements in discharge capacity are considered by changing the shape of the components to maximize the internal volume. The figure shows an air-zinc button cell as an example. The structure shown in FIG. 1 improves the discharge capacity by 20 to 30% compared to the conventional structure shown in FIG. 2, but this is caused by the difference in shape between the negative electrode sealing plates 3 and 3'. That is,
The one in Figure 1 does not have a bent part around the sealing plate, and the second
The one in the figure has a 3° outward and upward bend at the periphery, and this difference in shape gives the battery internal volume a difference in size.

銀電池。In recent years, the structure shown in FIG. 1 has been attracting attention as a method of increasing the volume of the negative electrode sealing plate as much as possible as a means of improving the performance and capacity of batteries. In a battery using an alkaline electrolyte, the material of the negative electrode sealing plate 3 shown in FIG. 1 is a three-layer cladding material of nickel-stainless steel nl-copper from the outside. Although the structure shown in Figure 1 allows the internal volume to be expanded, it is a silver oxide battery.

紙、９は空気孔である。In batteries that use an alkaline electrolyte and zinc for the negative electrode, such as mercury batteries, alkaline manganese batteries, and air 111i lead-acid batteries, if the electrolyte penetrates into the 8 parts, intense hydrogen gas will be released from the nickel surface and stainless steel surface (SUS304). This caused a decrease in discharge capacity and the generation of hydrogen gas, resulting in liquid leakage, and this 4X was unsuitable as a battery structure with high practical value. In the figure, 1 is the positive electrode case, 2
4 is a gas diffusion electrode, 4 is a gelled negative electrode zinc, 6 is a separator, 6 is a PTFE membrane, 7 is an insulating gasket, 8 is a positive electrode holding paper, and 9 is an air hole.
本発明は第１図に示す構造のもつ欠点を解決したもので
、以下実施例を含めて詳述する。The present invention solves the drawbacks of the structure shown in FIG. 1, and will be described in detail below, including examples.

The purpose of this is to prevent infiltration of electrolyte and to fill gaps between various structural members.

されてきたシール剤の中に、水素過電圧の高い金属の塩
を導入したものである。以下、実施例について説明する
。The present inventors discovered that hydrogen gas generation occurs violently on the nickel surface in the structure shown in Figure 1, and that this can be prevented by applying a substance with a high hydrogen overvoltage to this end in some way. We have discovered that it is possible to significantly reduce the The present invention provides a means for achieving this goal and can be industrialized very easily. Specifically, the present invention introduces a metal salt having a high hydrogen overvoltage into a conventionally used sealant. Examples will be described below.
Ｒ４４型の空気・亜鉛ボタン型電池を従来と同様にして
組み立て第１図の構造のものをつくる。An R44 type air/zinc button battery is assembled in the same manner as before to create the structure shown in Figure 1.
本発明ではシール剤中に過塩素酸亜鉛を１０重叶チ添加
した。シール剤にはクロロスルフオネーテノドポリエチ
レンをドルオールに溶解したものを使用した。従来例は
本発明品と同じ材質の７−ル剤だけを同一量ａ部に塗着
した。In the present invention, 10 times more zinc perchlorate was added to the sealant. The sealant used was chlorosulfonate polyethylene dissolved in doluol. In the conventional example, only the same amount of the 7-lue agent made of the same material as the product of the present invention was applied to part a.
この発明品と従来品を温度４６℃、湿度９０％に導入し
て耐漏液性ならびに６２０Ωの負荷抵抗を用いて放電容
量を調査した結果を次表に示す。This invention product and the conventional product were introduced at a temperature of 46° C. and a humidity of 90%, and the leakage resistance and discharge capacity were investigated using a load resistance of 620Ω. The results are shown in the following table.
＊１ｏＯ個保存して、漏液したものの個数このように本
発明品はすぐれているが、その原因、は前述したように
、アルカリ電解液がシール剤と負極封口板間に浸入した
場合、シール剤から亜鉛がすばやく溶解析出してガス発
生を抑えることによると推定される。*Number of items that leaked after storing 1oO items The product of the present invention is excellent as described above, but the reason for this is, as mentioned above, when the alkaline electrolyte enters between the sealant and the negative electrode sealing plate, the seal It is presumed that this is because zinc quickly dissolves out from the agent and suppresses gas generation.
前記実施例では過塩素酸亜鉛を掲げたが、ホウ弗化亜鉛
を用いることができる。他の塩としては、銅塩類も同様
に用いることができる。またそのシール剤への添加量は
６重量％以下では量が少な過ぎるため電解液中の溶解析
出時間が長くかかる。Although zinc perchlorate was used in the above examples, zinc borofluoride may also be used. As other salts, copper salts can be used similarly. Furthermore, if the amount added to the sealant is less than 6% by weight, the amount is too small and it takes a long time to dissolve it in the electrolytic solution.
逆に２６重量％以上では添加量が。多すぎ、樹脂系の充
填剤の性質が失われるため、６〜２０重量％が適切であ
った。On the other hand, if the amount is 26% by weight or more, the amount added will increase. If too much, the properties of the resin-based filler would be lost, so 6 to 20% by weight was appropriate.
