Title (EN) RECHARGEABLE LITHIUM-ION CELL WITH TRIPHENYLAMINE REDOX SHUTTLE
(FR) PILE AU LITHIUM RECHARGEABLE AVEC NAVETTE REDOX A LA TRIPHENYLAMINE
Abstract: front page image
(EN)Provided is a rechargeable lithium-ion cell that contains a positive electrode, a negative electrode, a charge-carrying electrolyte containing a charge carrying medium and a lithium salt, and a triphenylamine compound dissolved in or dissolvable in the electrolyte. The triphenylamine compound has an oxidation potential above the positive electrode recharged potential and serves as a cyclable redox chemical shuttle providing cell overcharge protection. Also provided are methods for manufacturing a rechargeable lithium-ion cell.
(FR)La présente invention concerne une pile au lithium rechargeable, qui comprend une électrode positive, une électrode négative, un électrolyte porteur de charge renfermant un milieu porteur de charge et un sel de lithium, et un composé de triphénylamine dissous ou pouvant être dissous dans l'électrolyte. Ledit composé possède un potentiel d'oxydation supérieur au potentiel rechargé de l'électrode positive et sert de navette chimique d'oxydoréduction cyclique assurant une protection de la pile contre les surcharges. L'invention concerne également des procédés de fabrication d'une pile rechargeable au lithium.
