Description

【発明の詳細な説明】 産業上の利用分野 本発明は密閉形鉛蓄電池の改良に関するものである。
従来の技術 従来フィルムパックにより極板群を覆納する密閉形鉛蓄
電池は、その極柱封口に際し、極柱に樹脂コーテングを
施こしてフィルムと熱溶着したり、極柱を樹脂でインジ
ェクション成形して、その成形体をフィルムと熱溶着さ
せたりする方式が一般的である。
発明が解決しようとする問題点 このような極柱封目方式では、極柱封口部からの電解液
の漏液を完全に防止することができ、特に負極極柱での
信頼性が低い。またフィルムが薄いため、たとえポリ塩
化ビニリデン等の水蒸気透過性の低いフィルムを用いた
としても、高温度、低湿度雰囲気では電解液のフィルム
からの散逸が除去しきれず電池寿命を低下させる等の欠
点を有していた。
問題点を解決するための手段 本発明は上記の如き欠点を除去するもので、密閉形鉛蓄
電池として、鉛フィルムまたは鉛板を含み陽極と陰極の
絶縁層を有するラミネートフィルムで極板群を覆納し、
鉛または鉛板の一部を極柱と接続して鉛または鉛合金で
封口するものである。
作用 漏液の信頼性がきわめて高くなり、また水蒸気の透過を
完全に防ぎうる。
実施例 鉛フィルム１を中央部に熱溶着面にポリブロピレンフィ
ルム２、外装面にポリエステルフィルム３を施した３層
のラミネートフィルム４を用いて極板群を１納した。な
お電池中央部のフィルムは陽極板５、陰極板６の絶縁を
保つため鉛フィルムを含まぬ絶縁層７としている。極板
群は、陽極板５を１枚、陰極板６を１枚使用した掻板構
成とした。極柱封口部は、第２図に示すように、極柱８
にラミネートフィルム４の中央部の鉛フィルム１と半田
部９において半田により極柱８の周囲を接続密閉し、さ
らにこの上部にエポキシ樹脂１０を流し込んだ。また熱
溶着を完全にするため、エポキシ樹脂ｌＯの上に塩素化
ポリプロピレンを塗付した。その後ラミネートフィルム
４の周囲を第１図に示す如く熱溶着部１１にて熱溶着し
、未決溶着部１２に電解液を注入後オイルを浸入させオ
イルミール弁１３とした。
このような方式により、５００　ｍ　Ａｈの電池を３個
作製し、５００　ｍＡ放電、２４５ｖ定電圧充電にて寿
命試験を行った。その結果、２５０サイクル経過時にお
いては、漏液、重量減、容量劣化はみられていない。
極柱封口部からの漏液またフィルムからの電解液の散逸
を防ｌトし、さらに製造が容易で安価に製造することが
できる等工業的価値甚だ大なるものである。
