Title
(EN) CATHODE ELECTRODE COMPOSITIONS FOR BATTERY APPLICATIONS
(FR) COMPOSITIONS D'ÉLECTRODE DE CATHODE POUR DES APPLICATIONS DE BATTERIE
Abstract
(EN)
Carbon nanostructures are used to prepare electrode compositions for lithium ion batteries. In one example, a cathode for NCM batteries includes three-dimensional carbon nanostructures which are made of highly entangled nanotubes, fragments of carbon nanostructures and/or fractured nanotubes which are derived from the carbon nanostructures, are branched and share walls with one another. Amounts of carbon nanostructures employed can be less than or equal to 1 weight % relative to the electrode composition.
(FR)
La présente invention concerne des nanostructures de carbone qui sont utilisées pour préparer des compositions d'électrode pour des batteries au lithium-ion. Dans un exemple, une cathode pour batteries NCM comprend des nanostructures de carbone tridimensionnelles qui sont constituées de nanotubes hautement enchevêtrés, de fragments de nanostructures de carbone et/ou de nanotubes fracturés qui sont dérivés des nanostructures de carbone, sont ramifiés et partagent des parois les uns avec les autres. Les quantités de nanostructures de carbone utilisées peuvent être inférieures ou égales à 1 % en poids par rapport à la composition d'électrode.
