A high yield strength steel plate is used to form a battery can. The steel plate has mechanical characteristics that the YP (yielding point) thereof is not less than 250N/mm2 and not more than 700N/mm2 and the HR30T (hardness) thereof is not less than 55 and not more than 80. As the high yield strength steel plate, steel plates of T-3 through T-5 and DR-8 through DR-10 of JIS G 3303 are used.
Cette invention concerne une enveloppe de pile électrique faite de tôle d'acier à haute limite élastique. L'acier est caractérisé par une limite élastique comprise entre 250 N/mm2 et 700 N/mm2 et un indice de dureté HR30T compris entre 55 et 80. Pour obtenir la haute limite élastique recherchée, on utilise des aciers de nuance T-3 à T-5 et DR-8 à DR-10, selon JIS G 3303.
