Abstract[English]
A process for producing an electrochemically active oxide material is described. The process comprises the steps of: providing particles of a precursor of the electrochemically active oxide material; granulating the precursor particles using roll compaction to form a granulated material; heat treating the granulated material to form a heat-treated material; and optionally de-agglomerating the heat-treated material. The material produced by the process is useful in the production of an electrochemically active oxide material.[French]
L'invention concerne un procédé de production d'un matériau d'oxyde électrochimiquement actif. Le procédé comprend les étapes consistant à : fournir des particules d'un précurseur du matériau d'oxyde électrochimiquement actif ; réaliser la granulation des particules de précurseur au moyen d'un compactage par rouleau pour former un matériau granulé ; traiter de manière thermique le matériau granulé pour former un matériau traité thermiquement ; et éventuellement réaliser la désagglomération du matériau traité thermiquement. Le matériau produit par le procédé est utile dans la production d'un matériau d'oxyde électrochimiquement actif.
