これらの試料番号1〜28の試料から57mm径でブランクを打ち抜いた後、鉄−ニッケル合金層とニッケル層のみを設けた側が容器外面となるようにして、10段の絞り加工により、外径13.8mm、高さ49.3mmの円筒形のLR6型電池(単三型電池)容器に成形加工した。
この電池容器を用いて、以下のようにしてアルカリマンガン電池を作成した。二酸化マンガンと黒鉛を10:1の比率で採取し、水酸化カリウム(10モル)を添加混合して正極合剤を作成した。次いで、この正極合剤を金型中で加圧して所定寸法のドーナツ形状の正極合剤ペレットに成形し、上記の電池容器に圧挿入した。なお、一部の電池容器は、内面に黒鉛粉末を主成分とする塗料を塗布したものを用いた。次に、負極集電棒をスポット溶接した負極板を電池容器に装着した。次いで、ビニロン製織布からなるセパレータを、電池容器に圧挿入した正極合剤ペレットの内周に沿うようにして挿入し、亜鉛粒と酸化亜鉛を飽和させた水酸化カリウムからなる負極ゲルを電池容器内に充填した。さらに、負極板に絶縁体のガスケットを装着して電池容器内に挿入した後、カシメ加工を施してアルカリマンガン電池を作成した。
以上のようにして試料番号1〜28の試料から作成した電池容器を用いて作成した電池の特性を、以下のようにして評価した。
電池を80℃で3日間放置した後、電池に電流計を接続して閉回路を設けて電流値を測定し、これを短絡電流とした。短絡電流が大きいほど特性が良好であることを示す。
電池を80℃で3日間放置した後、電池を1.5Aの一定電流に放電し、電圧が0.9Vに到達するまでの時間を放電時間として測定した。放電時間が長いほど放電特性が良好であることを示す。
重付加間歇放電の評価として、2Aで0.5秒放電した後に0.25Aで29.5秒放電する操作を1サイクルとして、このサイクルを繰り返し、電圧が1.0Vに到達するまでのサイクル数を測定した。サイクル数が多いほど間歇放電特性が良好であることを示す。
