Abstract
La présente invention concerne le domaine technique des matériaux d'électrode positive de batterie lithium-ion et concerne un procédé de préparation destiné à un matériau d'électrode positive d'oxyde de cobalt-lithium nanométrique et l'utilisation associée. Le procédé de préparation comprend les étapes suivantes : le mélange d'une solution de carbonate et d'un agent dispersant jusqu'à ce qu'il soit homogène, l'ajout d'une solution de sel de cobalt pour la réaction, puis son vieillissement et son filtrage, l'élimination de résidus de filtre et son séchage pour obtenir de la poudre de coco3 nanométrique, puis sa calcination pour obtenir un précurseur de co3o4, le mélange du précurseur de co3o4 avec un sel de lithium, puis son frittage, son refroidissement, son concassage et son tamisage pour obtenir le matériau d'électrode positive à base d'oxyde de cobalt-lithium nanométrique. La présente invention présente les avantages principaux du procédé de synthèse du coco3 nanométrique qui est simple et facile à contrôler, le processus étant court, en particulier la régulation fine de la température n'étant pas nécessaire, et des conditions telles que la valeur de ph n'ayant également pas besoin d'être contrôlées avec précision pendant le processus de réaction. La présente invention convient à une production industrielle à grande échelle.
