In this figure, 1 is zinc oxide, 2 is a sealing plate, 3 is a sealing packing, 4 is a separator, 5 is an air electrode, 6 is an air diffusion paper, 7 is a positive electrode case, 8 is an air hole, and 9 is a sealing paper , 10 is a porous Teflon membrane.
空気電池は空気中の酸素を空気孔より電池内に取り込む
ため１．空気孔を通じて外界と接している。1. Air batteries take oxygen from the air into the battery through the air holes. It is in contact with the outside world through air holes.
この結果、１力月を越える放電では外界の影響をうけて
十分な性能が得られないという問題があった。As a result, there has been a problem that sufficient performance cannot be obtained when the discharge exceeds one month due to the influence of the outside world.
この点の改良として、従来は多孔性テフロン膜の透過性
を放電に必要な最少値まで減少させる努力がなされてい
た。また本発明者らの検討では一般的な空気ボタン電池
に必要な透過性はＪＩＳ８１１７の規定による透気度と
して７００００秒以下が必要であることが判っている。To improve this point, efforts have been made to reduce the permeability of porous Teflon membranes to the minimum value necessary for discharge. In addition, the inventors have found that the permeability required for a general air button battery is 70,000 seconds or less as defined by JIS 8117.
発明が解決しようとする課題 従来の多孔性テフロンの製造方法は下記の通りである。Problems that the invention aims to solve The conventional method for manufacturing porous Teflon is as follows.
（１）テフロンのファインパウダーとフィラーを混合し
、フィルム状に成形する。(1) Mix Teflon fine powder and filler and form into a film.
（２） フィラーを除却し、細孔をあける。(2) Remove the filler and open pores.
（３）フィルムを延伸しその透過性をコントロールする
。(3) Stretch the film and control its transparency.
この方法では前述した透気度７００００秒まで透過性を
減少させることが非常に困難であり、また作成しても透
過性のバラツキが非常に大きくなることが判っている。It has been found that with this method, it is very difficult to reduce the permeability to the above-mentioned air permeability of 70,000 seconds, and even if it is produced, the variation in permeability will be very large.
また、この従来の方法では安定して生産できる限界は透
気度５０００秒以下が限界であった。Furthermore, in this conventional method, the limit for stable production was an air permeability of 5000 seconds or less.
課題を解決するための手段
この問題点を解決するため、本発明は従来の方法で作成
した多孔性テフロン膜を圧縮し、その透過性を減少させ
たものである。Means for Solving the Problem To solve this problem, the present invention compresses a porous Teflon membrane prepared by conventional methods to reduce its permeability.
作用
この構成によれば多孔性テフロン膜の透過性を必要な最
少値まで減少させることが可能となり、透過性のバラツ
キが小さ（なる。この結果、１力月を越える長期放電を
行なっても安定した放電性能を得ることが可能となる。Effect: With this configuration, it is possible to reduce the permeability of the porous Teflon membrane to the required minimum value, resulting in small variations in permeability.As a result, it is stable even after long-term discharge exceeding one month. It becomes possible to obtain high discharge performance.
実施例 以下、本発明の詳細な説明する。Example The present invention will be explained in detail below.
本実施例における空気ボタン電池は第１図に示した従来
例と同一であり、相違点は１０の多孔性テフロン膜が圧
縮した物を用いたことである。The air button battery in this example is the same as the conventional example shown in FIG. 1, with the difference being that a compressed porous Teflon membrane of 10 layers was used.
次に実際に多孔性フィルムを作成し、ガーレ数の測定を
行なった。Next, a porous film was actually created and the Gurley number was measured.
（１）従来方法でガーレ数３０００秒をセンター値とし
作成した物（従来例１）。(1) An object created using the conventional method with the Gurley number of 3000 seconds as the center value (Conventional Example 1).
Ｃ）従来方法でガーレ数７００００秒をセンター値とし
作成した物（従来例２）。C) An object created using the conventional method with the Gurley number of 70,000 seconds as the center value (Conventional Example 2).
（３）上記の従来例１の多孔性フィルムを圧縮し、ガー
レ数７００００秒をセンター値として作成した物（実施
例１）。(3) A product prepared by compressing the porous film of Conventional Example 1 above and setting a Gurley number of 70,000 seconds as the center value (Example 1).
また、圧縮は２本のロール間で加圧して行なった。Further, compression was performed by applying pressure between two rolls.
次に、実際にガーレ数を測定し、透過性のバラツキを検
討したその結果が表１である。Next, the Gurley number was actually measured and the variation in transmittance was examined. Table 1 shows the results.
表
表１から明らかなように、本実施例では従来例２に比較
して透過性のバラツキが小さいことが判る。As is clear from Table 1, it can be seen that in this example, the variation in transmittance is smaller than in Conventional Example 2.
次にＩＥＣ規格Ｒ４４型の空気ボタン電池を用い実際に
放電試験を行なった。その結果を第２図及び第３図に示
した。Next, an actual discharge test was conducted using an IEC standard R44 type air button battery. The results are shown in FIGS. 2 and 3.
第２図は負荷１３０Ω、温度２３℃における放電カーブ
であり、従来例２では一部透過性が不足して、放電電圧
が低下していることが判る。FIG. 2 shows a discharge curve at a load of 130Ω and a temperature of 23° C., and it can be seen that in Conventional Example 2, the transparency was partially insufficient and the discharge voltage was lowered.
第３図は負荷３．０にΩ、温度２３℃における放電カー
ブであり、従来例１の全数及び従来例２の一部において
、放電途中より放電電圧が低下している。これは、透過
性が必要以上にあり、外界の影響が大きいためである。FIG. 3 shows a discharge curve at a load of 3.0 Ω and a temperature of 23° C. In all of the conventional examples 1 and some of the conventional examples 2, the discharge voltage decreases from the middle of discharge. This is because there is more transparency than necessary and the influence of the outside world is large.
また、本実施例において、透過性のバラツキが従来例に
比較して小さく、１３０Ω〜３．ＯｋΩ負荷の範囲で安
定した放電性能が得られるのは多孔性テフロン膜の製造
上、ガーレ数５０００秒以下の領域において、最もバラ
ツキが小さく、これを圧縮することによってガーレ数７
００００秒の領域においても透過性のバラツキが小さい
物が得られるためである。Further, in this example, the variation in transmittance is smaller than that of the conventional example, and is 130Ω to 3.0Ω. Due to the manufacturing process of the porous Teflon membrane, stable discharge performance can be obtained in the OkΩ load range, and the variation is smallest in the region where the Gurley number is 5000 seconds or less, and by compressing this, the Gurley number is 7.
This is because it is possible to obtain a product with small variations in transmittance even in the region of 0,000 seconds.
なお、本実施例ではガーレ数３０００秒の物を圧縮した
が著者らの検討ではガーレ数５０００秒から５００秒の
範囲の物を圧縮しても同様の効果が得られた。In this example, an object with a Gurley number of 3000 seconds was compressed, but the authors' study found that the same effect was obtained even when compressing an object with a Gurley number of 5000 to 500 seconds.
発明の効果
以上の説明から明らかなように、空気ボタン電池に用い
る多孔性テフロン膜を圧縮し、その透過性を減少させた
物を用いると透過性のバラツキが小さく、かつ放電性能
の安定した空気ボタン電池を得ることができる。Effects of the Invention As is clear from the above explanation, by compressing the porous Teflon membrane used in air button batteries and reducing its permeability, it is possible to produce air with less variation in permeability and stable discharge performance. You can get button batteries.
