Abstract

La présente invention divulgue un procédé de préparation d'un oxyde de cobalt étroitement revêtu et son utilisation, le procédé de préparation comprenant : la synthèse de particules sphériques d'hydroxyde de cobalt par un procédé de coprécipitation ; après le séchage et la déshydratation de celles-ci, le mélange uniforme de celles-ci avec du carboxylate d'alkyle de zirconium / carboxylate d'alkyle d'aluminium et de l'hydroxyde de zirconium / hydroxyde d'aluminium et le chauffage du mélange pour permettre au carboxylate d'alkyle de zirconium / carboxylate d'alkyle d'aluminium et à l'hydroxyde de zirconium / hydroxyde d'aluminium de réagir avec l'hydroxyde de cobalt sur les couches de surface des particules, de façon à les fixer étroitement aux surfaces des particules sphériques d'hydroxyde de cobalt ; et enfin, la réalisation d'une calcination pour éliminer les matières organiques de façon à former des particules sphériques d'oxyde de cobalt avec des couches de revêtement proches sur les surfaces. En utilisant des liaisons chimiques pour relier les couches de revêtement et un matériau de base, la présente invention permet à ces deux éléments d'être plus étroitement fixés et non sujets à la pulvérisation et à la chute, ce qui permet de prolonger considérablement la durée de vie des couches de revêtement, et d'améliorer les performances de cycle du matériau.
