Abstract
Description
【発明の詳細な説明】 産業上の利用分野 本発明はボタン形空気電池の製造方法に関する。[Detailed description of the invention] Industrial applications The present invention relates to a method for manufacturing a button-type air battery.
従来の技術
従来、ボタン形空気電池は、嵌合前の封口リングの上部
外径をＡ、下部外径をＢ、正極ケースの上部内径をＣと
した場合にＡ＞Ｃ＞Ｂとなるように形成されていた。Conventional technology Conventionally, in button-type air batteries, when the upper outer diameter of the sealing ring before fitting is A, the lower outer diameter is B, and the upper inner diameter of the positive electrode case is C, A>C>B. had been formed.
この理由は、この種のボタン型電池は第３図の電池断面
におけるａ部の封口リング２よシ強く圧縮すると、耐漏
液性能が向上することが知られていたが、ボタン形空気
電池の場合は、ａ部の封口リング２を圧縮しようとする
と、ａ部のみが圧縮されずに電池底部のｂ部も圧縮され
てしまう。ｂ部には活性炭を主とした空気極５の周縁が
位置し、その強度は軟弱なためｂ部が圧縮されすぎるこ
とは空気極６の不必要な変形を招き、電池の内部抵抗が
上昇する。そのため、Ａ）Ｃ）Ｂとすることによって、
ｂ部を極端に圧縮をすることなく、ａ部を圧縮し、耐漏
液性能が向上させようとするものであった。The reason for this is that it is known that the leakage resistance of this type of button-type battery improves when it is compressed more strongly than the sealing ring 2 at section a in the cross-section of the battery in Figure 3; however, in the case of button-type air batteries, When trying to compress the sealing ring 2 at section a, only section a is not compressed, but section b at the bottom of the battery is also compressed. The periphery of the air electrode 5, which is mainly made of activated carbon, is located in part b, and its strength is weak, so if part b is compressed too much, the air electrode 6 will be unnecessarily deformed, and the internal resistance of the battery will increase. . Therefore, by setting A)C)B,
The aim was to compress part a without excessively compressing part b, thereby improving leakage resistance.
発明が解決しようとする問題点
しかし、Ａ）Ｃ＞Ｂなる形成をすると、Ａ＞Ｃのため、
電池内が電池封口前に密閉され、ポンプアップの原理に
よシ、対日直後に電解液が電池容器より流出し、むしろ
初期の耐漏液性能は悪くなる傾向があった。Problems to be solved by the invention However, if we form A) C>B, then because A>C,
The inside of the battery was sealed before the battery was sealed, and due to the pump-up principle, the electrolyte leaked out of the battery container immediately after exposure to Japan, and the initial leakage resistance tended to deteriorate.

を正極ケースに嵌合させることを特徴とする。Means for Solving the Problems The method for manufacturing a button-type air battery of the present invention is to attach a sealing ring with a cross-section shape to the outer periphery of a negative electrode case, and attach this to the positive electrode with a positive electrode material placed on the inner bottom. When fitting the sealing ring inside the case and tightening the sealing ring between the negative electrode case and the positive electrode case to form a button-type air battery, the upper outer diameter of the sealing ring before fitting is A, the lower outer diameter is B, and the positive electrode It is characterized in that the negative electrode case and the sealing ring, which are formed on the case so that the maximum tolerance value of B and the minimum tolerance value of D are equal, are fitted into the positive electrode case.
