(FR) PROCÉDÉ POUR LA PROTECTION DE MATÉRIAUX D'ÉLECTRODE CONTRE L'HUMIDITÉ
Abstract
(EN)
The invention relates to a method or process for modifying the surface of carbon-coated electrochemically active materials such as complex oxides like olivine-type cathode materials. For example, the surface of the carbon-coated material is modified in order to improve the hydrophobic properties thereof. In addition, specific groups can be grafted onto the carbon surface of the cathode material by means of diazonium chemistry, for example, by spontaneous grafting of aryl ions generated on-site by the diazotisation of an arylamine compound.

Est décrit une méthode ou procédé pour la modification de la surface de matériaux électrochimiquement actifs enrobés de carbone tels que les oxydes complexes comme les matériaux de cathode de type olivine. Par exemple, la surface du matériau enrobé de carbone est modifiée afin d'augmenter ses caractéristiques hydrophobes. Aussi, des groupes spécifiques peuvent être greffés sur la surface de carbone du matériau de cathode par l'utilisation de la chimie du diazonium, par exemple, par le greffage spontané d'ions aryles générés in situ par la diazotization d'un composé arylamine.
