Abstract

Elément rechargeable isolé de l'atmosphère environnante comportant une électrode négative par exemple, en LaNi5 ou un composé intermétallique en déduit, comportant à l'électrode négative une plus grande quantité de masse électrochimiquement active qu'à l'électrode positive, l'excès de masse négative à l'état complètement déchargé de l'électrode positive se trouvant partiellement à l'état chargé (ce qui veut dire, se trouvant partiellement sous forme d'hydrure). Application : Elément électrochimique rechargeable.Rechargeable element isolated from the surrounding atmosphere comprising a negative electrode, for example, in LaNi5 or an intermetallic compound derived therefrom, comprising at the negative electrode a greater quantity of electrochemically active mass than at the positive electrode, the excess of negative mass in the fully discharged state of the positive electrode being partially in the charged state (that is to say, being partially in the form of hydride). Application: Rechargeable electrochemical element.
