Description
[発明の実施のための形態]
以下、実施例及び実験例を挙げてさらに説明するが、本発明がこれらの実施例及び実験例により制限されるものではない。
<防錆性ワッシャーの製造>
NaNO2を常温、常圧で均一な性状をなすまでよく交ぜた後、細かく粉砕させた。前記粉砕されたNaNO2を溶融されたポリプロピレン樹脂と混合させて気化性防錆剤(VCI)を得た。
Niをメッキした SPCE(冷間圧延鋼板)を用いて上端キャップ及び円筒状缶を製作し、円筒状缶に電極組立体を取り付けた後、図3のように防錆性ワッシャーをキャップアセンブリーの上端キャップを包みながらビーディング部上端に搭載し、 熱収縮性チュービングで缶の外面を包みながらキャップアセンブリーの上端部を密封して円筒状二次電池を製作した。
気化性防錆剤を用いず、ベース樹脂としてYUPO合成樹脂素材のワッシャーを用いたとの点を除いては、実施例 1と同一の方法で円筒状二次電池を製作した。
気化性防錆剤を用いず、ベース樹脂としてポリプロピレン素材のワッシャーを用いたとの点を除いては、実施例 1と同一の方法で円筒状二次電池を製作した。
比較例 1と 2 及び実施例 1で製造されたワッシャーをそれぞれ 50個ずつ円筒状電池に組み立てて図5のようにビニールに密封した状態で恒温恒湿チャンバで約 65℃、 90% R.H 条件で 7日間保管した後、電池のクリンピング部の錆発生個数をよく見て比較した。
