Title (EN) CO-CRUSHED MIXTURE OF AN ACTIVE MATERIAL AND OF A CONDUCTIVE MATERIAL, PREPARATION METHODS AND USES THEREOF
(FR) MÉLANGE COBROYÉ D'UN MATÉRIAU ACTIF ET D'UN MATÉRIAU DE CONDUCTION, SES PROCÉDÉS DE PRÉPARATION ET SES APPLICATIONS
Abstract: front page image
(EN)The invention concerns a mixture of particles consisting of a carrier based on at least one active material M1of average size T1 and of specific surface S1 on which are bonded, via physical and/or chemical bonds, particles of at least an electronically conductive material M2 of average size T2 and of specific surface S2. The mixture is characterized in that: the average size ratio T1/T2 ranges between 5 and 10000; The specific surface ratio S1/S2 ranges between 1/300 and 1/2; and the amount of active material present in the mixture preferably represents more than 80% of the amount of the conductive material. The incorporation of said mixtures into elements constituting electrochemical systems substantially improves the performances of the latter.
(FR)Mélange de particules constituées par un support à base d'au moins un matériau actif M1 de taille moyenne T1 et de surface spécifique Si sur lequel sont attachées, par des liaisons physiques et/ou chimiques, des particules d'au moins un matériau conducteur électronique M2 de taille moyenne T2 et de surface spécifique S2. Le mélange est caractérisé en ce que : le rapport des tailles moyennes T1/T2 est compris entre 5 et 10000; le rapport des surfaces spécifiques S1/S2 est compris entre 1/300 et 1/2; et la quantité de matériau actif présent dans le mélange représente de préférence plus de 80 % de la quantité du matériau conducteur. L'incorporation de ces mélanges dans les éléments constitutifs de systèmes électrochimiques améliore sensiblement les performances de ces derniers.
