Description
負極活物質として炭素を使用し、導電材としてカーボンブラック、バインダーとしてSBR、CMCを使用して負極スラリーを製造し、10μmCuホイルの上にスラリーを塗布、乾燥、圧延して負極を製造した。正極活物質としてNi rich NMC複合酸化物を使用し、導電材としてカーボンブラック、バインダーとしてPVdFを使用して正極スラリーを製造し、15μmAl ホイルの上にスラリーを塗布、乾燥、圧延して正極を製造した。これらの正極と負極との間に分離フィルムを介在した後、巻取してジェリーロール形状の電極組立体を製造した。
図7に図示されたキャップアセンブリ構造及び図2、3に図示された缶部材を含む円筒型缶に前記の製造された電極組立体を電解液と共に収納して円筒型二次電池を製造した。このとき、鋼素材の缶部材の一部に含まれた形状記憶合金部材は、ニッケル−チタン合金であって、130℃以上の温度にて膨張し、缶部材の体積膨張率の130%である。
前記の缶部材全体が、一般的な鋼素材であることを除いては、実施例と同様の方法で円筒型二次電池を製造した。
実施例及び比較例の二次電池を、135℃の温度にて10分間に放置した後、発火の可否を目視で確認し、その結果を図10aおよび図10bに示した。
