Abstract

La présente invention concerne un procédé de préparation de carbonate de cobalt dopé à l'aluminium ayant une morphologie en flocon et son utilisation. Le procédé de préparation comprend : un premier mélange d'un sel de cobalt, un sel d'aluminium et un composé polyhydroxy pour préparer une solution mixte, puis le mélange de la solution mélangée avec une solution de bicarbonate d'ammonium, le réglage du pH, la mise en œuvre d'une réaction pendant le chauffage et l'agitation pour obtenir une solution de germe cristallin, puis l'ajout de la solution mélangée et la solution de bicarbonate d'ammonium à la solution de germe cristallin, le réglage du pH, et la mise en œuvre d'une réaction pendant le chauffage et l'agitation. La teneur en solides de la bouillie est régulée à 20-40 % dans le procédé de réaction jusqu'à ce que la taille de particule des particules dans la bouillie augmente jusqu'à une valeur cible, et la phase solide est séparée, lavée et séchée pour obtenir du carbonate de cobalt dopé à l'aluminium ayant une morphologie en flocon. Dans la présente invention, par ajout du composé polyhydroxy et par régulation de la concentration de la suspension de système, on peut obtenir une transformation complète de formes cristallines de carbonate de cobalt dopé à l'aluminium ayant différentes tailles de particule ; le carbonate de cobalt dopé à l'aluminium préparé présente une meilleure uniformité, une morphologie régulière, une distribution uniforme d'aluminium, aucun enrichissement en aluminium évident, aucune micro-poudre, et une distribution de taille de particule concentrée.
