Title (EN) CARBON-COATED ACTIVE PARTICLES AND PROCESSES FOR THEIR PREPARATION
(FR) PARTICULES ACTIVES REVÊTUES DE CARBONE ET PROCÉDÉS POUR LEUR PRÉPARATION
Abstract: front page image
(EN)This application describes a process for the preparation of carbon-coated particles, where the particles comprise an electrochemically active material. The process comprises the steps of emulsion polymerization, drying and thermally treating the polymer to obtain a nano-layer of carbon on the particles, where the carbon layer comprises fibers and nitrogen-containing polyaromatics have a graphene-like structure. The application also further relates to the particles produced by the method as well as to electrode materials, electrodes and electrochemical cells comprising the particles.
(FR)Cette invention concerne un procédé de préparation de particules revêtues de carbone, les particules comprenant une substance électrochimiquement active. Le procédé comprend les étapes de polymérisation en émulsion, de séchage et de traitement thermique du polymère pour obtenir une nanocouche de carbone sur les particules, la couche de carbone comprenant des fibres et des composés polyaromatiques contenant de l'azote ayant une structure du type graphène. L'invention concerne également les particules produites par le procédé, ainsi que des matériaux d'électrode, des électrodes et des cellules électrochimiques comprenant les particules.
