A composite electrical battery and a method for forming a composite electrical battery. The composite electrical battery includes a primary electrochemical cell and a fully or partially discharged rechargeable electrochemical cell. The rechargeable electrochemical cell is electrically connected in parallel to the primary electrochemical cell. The open circuit voltage of the primary electrical chemical cell is lower than the open circuit voltage of the rechargeable cell when the rechargeable cell is fully charged. The self discharge rate of the rechargeable electrochemical cell after electrically connecting the rechargeable cell to the primary electrochemical cell is less than a self discharge rate.

L'invention porte sur une batterie électrique composite et sur son procédé de fabrication. Cette batterie électrique composite comprend une cellule électrochimique primaire et une cellule électrochimique rechargeable totalement ou partiellement déchargée. La cellule électrochimique rechargeable est connectée électriquement en parallèle à la cellule électrochimique primaire. La tension de circuit ouvert de la cellule électrochimique primaire est inférieure à celle de la cellule rechargeable lorsque cette dernière est chargée à fond. La vitesse de décharge spontanée de la cellule électrochimique rechargeable après connexion électrique de la cellule rechargeable à la cellule électrochimique primaire est inférieure à une vitesse de décharge spontanée.
