Des produits d\u00e9riv\u00e9s mettant en circulation une suspension de m\u00e9tal dans un \u00e9lectrolyte, comme par exemple du Zinc en poudre dans une solution de potasse, le long de faisceaux de tubes \u00e9quip\u00e9s \u00e0 l’ext\u00e9rieur d’\u00e9lectrodes \u00e0 air, permettent d’atteindre des densit\u00e9s de courant compatibles avec les puissances appel\u00e9es pour tracter un v\u00e9hicule. On peut donc imaginer un v\u00e9hicule \u00e9lectrique \u00e9quip\u00e9 par exemple d’une batterie Ni-MH hybride actuelle qui assurera les pointes de courant et la r\u00e9cup\u00e9ration de l’\u00e9nergie au freinage, associ\u00e9e \u00e0 une pile \u00e0 circulation de type air-zinc qui apporte l’\u00e9nergie \u00e9lectrique n\u00e9cessaire \u00e0 une longue autonomie (1000 km ou plus). Toyota affirme travailler s\u00e9rieusement sur ce types de syst\u00e8mes pour ses futurs v\u00e9hicules \u00e9lectriques de longue autonomie (FIG. zone bleue). \"Toyota_stockage\"<\/a> <\/p>\n

               Le succ\u00e8s d’une telle option repose sur de nombreux param\u00e8tres:<\/p>\n

    \n
  1. le choix du m\u00e9tal ou de l’alliage en circulation,<\/li>\n
  2. la ma\u00eetrise de l’\u00e9lectrode \u00e0 air (retomb\u00e9e des \u00e9tudes sur les Piles \u00e0 combustible),<\/li>\n
  3. la miniaturisation de toute la partie hydraulique et des \u00e9l\u00e9ments de pile,<\/li>\n
  4. la ma\u00eetrise thermique et \u00e9lectrique du syst\u00e8me,<\/li>\n
  5. la possibilit\u00e9 de recharger \u00e9lectriquement le syst\u00e8me pour \u00e9viter de fastidieuses vidanges des \u00e9lectrolytes usag\u00e9s, suivies de remplissages avec des suspensions neuves.<\/li>\n<\/ol>\n

                          D\u00e9finitivement l’introduction d’un moteur \u00e9lectrique dans une voiture ouvre la voie \u00e0 bien des solutions et bien des perfectionnements dont nous n’apercevons que les pr\u00e9mices. Les "Sakichi Batteries", du pr\u00e9nom du fondateur de Toyota (FIG.), verront peut-\u00eatre le jour dans un futur lointain pour totalement r\u00e9volutionner le stockage embarqu\u00e9 de l’\u00e9nergie. <\/p>\n
