Abstract

Une méthode comprend : la fourniture d'une solution de sel métallique comprenant du nickel, du cobalt, du manganèse, de l'aluminium, ou une combinaison de ceux-ci ; la combinaison de la solution de sel métallique avec une solution basique, la combinaison de la solution de sel métallique et de la solution basique étant maintenue à un pH inférieur ou égal à 10 pour former un précurseur d'hydroxyde métallique. Pour former un matériau actif de cathode, la méthode comprend en outre l'ajout d'un composé de lithium au précurseur d'hydroxyde métallique pour former un mélange précurseur d'hydroxyde métallique ; et le traitement thermique du mélange précurseur d'hydroxyde métallique pour former le matériau actif de cathode monocristallin.
