Title (EN) A NEGATIVE ELECTRODE COMPOSITION FOR LITHIUM SECONDARY BATTERIES, A METHOD FOR THE PRODUCTION THEREOF, USE OF SAID COMPOSITION IN LITHIUM SECONDARY BATTERIES AND LITHIUM SECONDARY BATTERIES CONTAINING SAID NEGATIVE ELECTRODE COMPOSITION
(FR) COMPOSITION D'ELECTRODE NEGATIVE DESTINEE A DES ACCUMULATEURS AU LITHIUM, PROCEDE DE FABRICATION, UTILISATION DE CETTE COMPOSITION DANS LES ACCUMULATEURS AU LITHIUM ET ACCUMULATEURS AU LITHIUM CONTENANT CETTE COMPOSITION D'ELECTRODE NEGATIVE
Abstract:
(EN) The invention relates to a negative electrode composition for lithium secondary batteries comprising at least 10 % by weight of a carbon black having a specific BET surface area of at most 20 m2/g, preferably of 2 to 20 m2/g and a method for the production thereof wherein a carbon black and optionally a more ordered carbon material, preferably coke and/or graphite, is ground in a solvent containing a binder so as to produce a uniform, viscous slurry, followed by coating of the slurry onto a substrate, preferably a metal foil substrate, evaporation of the solvent and drying at elevated temperature. The invention also relates to the use of this negative electrode composition for the manufacturing of lithium secondary batteries as well as a lithium secondary battery comprising such a negative electrode composition.
(FR) Composition d'électrode négative destinée à des accumulateurs au lithium, comprenant au moins 10 % en poids d'un noir de carbone présentant une surface spécifique BET de 20 m2/g au plus, de préférence de 2 à 20 m2/g, et procédé de fabrication de celle-ci. Un noir de carbone, et éventuellement un matériau carboné plus ordonné, de préférence coke et/ou graphite, est broyé dans un solvant contenant un liant, ce qui produit une boue uniforme et visqueuse. Cette boue est ensuite appliquée sur un substrat, de préférence une feuille métallique, avant évaporation du solvant et séchage à haute température. L'invention concerne également l'utilisation de cette composition d'électrode négative pour la fabrication d'accumulateurs au lithium, ainsi qu'un accumulateur au lithium comprenant cette composition d'électrode négative.
