Abstract

Prise de contact électrique sur un feuillard d'anode d'un générateur au lithium à
électrolyte polymère, constitué d'une ou plusieurs cellules électrochimiques multicouches. La cellule comprend au moins un feuillard à base de lithium d'épaisseur comprise entre environ 1 et 50 microns formant l'anode et son collecteur et comporte en outre une cathode et son collecteur de même que l'électrolyte polymère. Une extrémité latérale du feuillard d'anode s'étend au-delà des extrémités correspondantes de la cathode et du collecteur pour constituer une zone de débordement. Une couche métallique constituée d'au moins un métal rigide et compatible avec le lithium est en contact électrique avec l'extrémité latérale du feuillard d'anode mais sans contact électronique avec les autres composantes de la cellule. La couche métallique constitue la borne externe du générateur en condition non habillé.
Selon une variante, une zone métallique intermédiaire conductrice et cohésive, constituée de lithium ou d'alliages ductiles riches en lithium est en contact intime avec l'extrémité latérale du feuillard d'anode et la couche métallique mentionnée ci-dessus se trouve donc en contact électrique avec l'extrémité
latérale du feuillard d'anode par le truchement de la zone intermédiaire de lithium. On décrit des générateurs munis d'une telle prise de contact ainsi qu'un procédé de préparation de ces prises de contact.
