Patent

CA 2610706

The present invention includes an apparatus and method of making and using a composition that includes the replacement of electrochemically inactive additives with a conductive and electrochemically active polymer that is attached so as to make an electrical contract to the redox couples of the electrochemically active oxide particles into/from which Lithium is reversibly inserted/extracted in a battery discharge/charge cycle.

La présente invention concerne un dispositif et un procédé de fabrication et d'utilisation d'une composition permettant de remplacer des additifs électrochimiquement inactifs par un polymère conducteur électrochiniquement actif, lequel est fixé de manière à créer un contact électrique avec des couples d'oxydoréduction des particules d'oxyde dans lesquels/hors desquels le lithium est inséré/extrait de manière réversible au cours d'un cycle de décharge/charge de la batterie.
