Abstract

La présente invention concerne un procédé de préparation d'un précurseur ternaire, comprenant : tout d'abord, le mélange d'une première solution de sel métallique contenant un sel de nickel, un sel de cobalt et un sel de manganèse solubles, de l'hydroxyde d'ammonium et une solution d'hydroxyde de sodium, la régulation du ph, la réaction sous chauffage et agitation, et le vieillissement et la filtration d'une suspension épaisse obtenue pour obtenir un germe cristallin précurseur ; et ensuite, l'introduction du germe cristallin précurseur dans une solution acide diluée pour agitation, la filtration en vue d'obtenir un germe cristallin acidifié, le mélange d'une seconde solution de sel métallique contenant le sel de nickel, le sel de cobalt et le sel de manganèse solubles, la solution d'hydroxyde de sodium, et le germe cristallin acidifié, l'ajustement du ph, la réaction sous chauffage et agitation, et le vieillissement, la filtration et le séchage de la suspension épaisse obtenue pour obtenir le précurseur ternaire. Selon la présente invention, le germe cristallin précurseur est placé dans la solution acide diluée pour être agité, de sorte que la micropoudre amorphe sur la surface du germe cristallin est dissoute, une structure cristalline se développe, et les particules primaires deviennent également plus fines et plus minces dans la condition de lixiviation acide, créant ainsi des conditions favorables pour la croissance continue d'une plaquette le long de la surface du germe cristallin dans le processus ultérieur sans ammoniac.
