Des éléments d'électrode positive de type bande (20) et des éléments d'électrode négative de type bande (30) sont disposés sur la surface d'un séparateur de type courroie (10) dans la direction longitudinale du séparateur de type bande (10). Ledit séparateur de type bande (10) est courbé et réenroulé depuis une extrémité du séparateur de type courroie (10), formant ainsi un élément de batterie empilée (1) avec le séparateur de type courroie (10) interposé entre les éléments d'électrode positive (20) et les éléments d'électrode négative (30).
