Abstract

L'invention concerne un processus de mélange de matériau pour préparer un matériau d'électrode positive à haute teneur en nickel et son utilisation. Le processus de mélange de matériau consiste à : ajouter un précurseur et une source de lithium à un dispositif de mélange de matériau à mélanger pour obtenir un matériau mélangé, et après que le matériau mélangé a été mélangé de manière uniforme, pulvériser un liquide dans le matériau mélangé pendant que le dispositif de mélange de matériau continue à fonctionner, et évacuer le matériau après lachèvement de la pulvérisation de liquide, et placer le matériau mélangé ainsi obtenu dans une cassette en vue dun frittage, le liquide étant constitué d'un ou plusieurs éléments parmi l'eau pure, l'éthanol, la N-méthyl pyrrolidone, une solution additive ou une dispersion additive. Au moyen du processus de mélange par pulvérisation, le matériau mélangé peut être mélangé de manière plus uniforme, et en raison de la présence d'une quantité appropriée de gouttelettes de brume, la surface de la source de lithium est légèrement soluble dans l'eau, qui peut adsorber le précurseur, de telle sorte que la densité apparente du matériau mélangé soit améliorée, la quantité de charge dans le procédé de frittage soit augmentée de 5 à 40 %, et la productivité soit augmentée de 10 à 30 %.
