後、撥水性耐アルカリ性樹脂よりなる絶縁性バッキング
５を挿入する。In a conventional sealed battery, for example, as shown in FIG. 1, an anode mixture 2 formed into pellets is pressure-molded on the inner bottom of an anode wire 1, and then a microporous material such as an alkali-resistant polymerized metal material such as cellophane is injected into the inner bottom of an anode wire 1. A plastic separator 3 and an alkali-resistant electrolyte-impregnated material 4 made of synthetic fibers and natural fibers are placed thereon, and then an insulating backing 5 made of a water-repellent and alkali-resistant resin is inserted.
そして陰極合剤６を充填した陽極線７を挿入して上部よ
り押圧するクリンプにより密封口する。Then, the anode wire 7 filled with the cathode mixture 6 is inserted and the opening is sealed by a crimp that is pressed from above.
しかしながら封目する際電解液含浸材の周縁部が圧縮さ
れ吸収している。However, when sealing, the peripheral edge of the electrolyte-impregnated material is compressed and absorbed.
電解液が絞り出されて１と５の間のわずかな間隙を通っ
て電池外部に流出する。The electrolyte is squeezed out and flows out of the battery through the small gap between 1 and 5.
これがこの種の密閉型電池における漏液の原因の１つと
なっていた。This was one of the causes of leakage in this type of sealed battery.
そこで電解液含浸材の周縁部を撥水性・耐アルカリ性の
樹脂等で処理することも考えられているが、含浸材の周
縁部を均一に処理することは極めて困難であり、また煩
雑な工程が必要となる等の欠点を有していた。Therefore, it has been considered to treat the periphery of the electrolyte-impregnated material with water-repellent and alkali-resistant resin, but it is extremely difficult to uniformly treat the periphery of the impregnated material, and it requires a complicated process. It had disadvantages such as being necessary.
本考案は上記の点に鑑み、簡単な工程により、電解液の
漏れを防ぐことのできる密閉型電池を提供することを目
的とする。In view of the above points, an object of the present invention is to provide a sealed battery that can prevent electrolyte leakage through a simple process.

体が順次積層されてなる発電要素と、前記発電要素を加
圧封止により内装する容器をなす陽極線および陽極線と
、前記陽極線および陽極線がなす封止部に介装され絶縁
性バッキングとを具備した密閉型電池において、前記絶
縁性バッキングが前記セパレータおよび電解液含浸材が
挿着される段差部を有し、かつ前記絶縁性バッキングが
前記陽極体と接している密閉型電池である。The present invention includes a power generation element in which a cathode body, an electrolyte-impregnated material, a separator, and an anode body are laminated in order; an anode wire and an anode wire forming a container in which the power generation element is sealed by pressure; In a sealed battery comprising an insulating backing interposed in a sealing part formed by an anode wire, the insulating backing has a stepped part into which the separator and the electrolyte impregnated material are inserted, and the insulating It is a sealed battery in which a backing is in contact with the anode body.
つまり絶縁性バッキングに、電解液含浸材およびセパレ
ータが挿着される段差部を設けておくことにより、加圧
封止時の圧力が陽極体に加わることとなり、電解液含浸
材及びセパレータは圧縮されることもなく、従って電解
液が漏れることなく封止できるというものである。In other words, by providing a stepped portion in the insulating backing into which the electrolyte-impregnated material and separator are inserted, pressure during pressure sealing is applied to the anode body, and the electrolyte-impregnated material and separator are compressed. Therefore, the electrolyte can be sealed without leaking.
また、この絶縁性バッキングに設けられた段差部は、電
解液含浸材のストッパーの役割をもはたすので、位置決
め等が容易となり、製造上非常に有効である。Furthermore, the stepped portion provided on the insulating backing also serves as a stopper for the electrolyte-impregnated material, making positioning easy and very effective in manufacturing.
さらにこの段差部がストッパーとじての役割をはたすこ
とにより、電解液含浸材が動くことがない。Furthermore, since this stepped portion functions as a stopper, the electrolyte-impregnated material does not move.
従って電解液含浸材が例えば陰極体側にはいりこむこと
がない。Therefore, the electrolyte-impregnated material does not enter, for example, the cathode body side.
よって電解液含浸材が動くことによるセパレータとの分
離、接触不良等がなく、セパレータと電解液含浸材との
接触が良好かつ均一となり、電池の出力低下、寿命が短
くなる等のおそれがない。Therefore, there is no separation from the separator due to movement of the electrolyte-impregnated material, poor contact, etc., and the contact between the separator and the electrolyte-impregnated material is good and uniform, and there is no risk of a decrease in battery output or shortened battery life.

すなわち、セパレータと電解液含浸材を重ねた板材を同
時にうちぬいて成型することもできるし、セパレータと
電解液含浸材が一体化された２層構造の材料を用いるこ
