Abstract

L'invention porte sur un élément de batterie qui présente une enveloppe, ainsi qu'au moins un enroulement de batterie qui est disposé dans cette enveloppe et qui est relié électriquement par l'intermédiaire d'un premier élément récepteur de courant à une première connexion et par l'intermédiaire d'un second élément récepteur de courant à une seconde connexion, la première connexion et la seconde connexion étant disposées au moins partiellement à l'extérieur de l'enveloppe, et au moins un premier composant conducteur de la chaleur, qui est disposé entre l' enveloppe et le premier élément récepteur de courant et qui est en contact par surface intégrale avec ceux-ci, pour accroître la conduction thermique entre l'enveloppe et le premier élément récepteur de courant. De préférence, il est aussi prévu un second composant conducteur de la chaleur qui est disposé entre l'enveloppe et le second élément récepteur de courant et qui est en contact par surface intégrale avec ceux-ci pour accroître la conduction thermique entre l'enveloppe et le second élément récepteur de courant. Par ailleurs, l'invention porte aussi sur un procédé de fabrication pour un tel élément de batterie, ainsi que sur une batterie qui est composée d'au moins deux tels éléments de batterie.
