PROCESS FOR PREPARING A LITHIUM TRANSITION METAL OXIDE, INCLUDING A ROLL COMMPACTION STEP OF PRECURSOR MATERIALS
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 treati...

| description | 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.
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. |
