Abstract
La présente invention permet à la fois la suppression de la détérioration d'une première cellule et la suppression de la réduction de la densité d'énergie volumique d'une cellule de stockage d'énergie. Une cellule de stockage d'énergie selon l'invention comprend une première électrode positive, une seconde électrode positive présentant une capacité inférieure et une résistance interne inférieure à celles de la première électrode positive, et une électrode négative. Dans ladite cellule de stockage d'énergie, une première cellule composée de la première électrode positive et de l'électrode négative présente une résistance interne relativement élevée et présente une caractéristique capacitive relativement élevée. Une seconde cellule composée de la seconde électrode positive et de l'électrode négative présente une résistance interne relativement faible, et présente ainsi une caractéristique de sortie relativement élevée. Un premier rapport de capacité est le rapport de la capacité de la seconde électrode positive à la capacité de la première électrode positive, et est compris entre 0,7 et 10 % inclus.
