CA 2716265
The invention relates to a composite electrode material consisting of a carbon coated complex oxide, fibrous carbon and a binder. Said material is prepared by a method which comprises co- grinding an active electrode material and fibrous carbon, and adding a binder to the co-grinded mixture to lower the viscosity of the mixture. The fibrous carbon is preferably vapor grown carbon fibers.
L'invention porte sur un matériau composite d'électrode se composant d'un oxyde complexe carboné, d'un carbone fibreux et d'un liant. Ledit matériau est préparé par un procédé qui comprend le co-broyage d'un matériau actif d'électrode et d'un carbone fibreux et l'ajout d'un liant au mélange co-broyé pour abaisser la viscosité du mélange. Le carbone fibreux est, de préférence, des fibres de carbone produites en phase vapeur.
