Abstract

L'invention concerne un précurseur de matériau d'électrode positive dopé à l'aluminium, sa méthode de préparation et son utilisation. La méthode comprend : l'ajout d'une solution mixte de sels de nickel, de cobalt et de calcium, d'une première solution alcaline à base d'aluminium, d'eau ammoniacale et d'une solution d'hydroxyde de sodium à une solution de base pour réaction ; la réalisation d'une séparation solide-liquide pour obtenir un gâteau de filtration ; le trempage du gâteau de filtration dans une seconde solution alcaline à base d'aluminium ; la réalisation d'une séparation solide-liquide pour obtenir un matériau solide ; la calcination du matériau solide ; et le trempage du matériau calciné dans de l'eau pour obtenir le précurseur de matériau d'électrode positive dopé à l'aluminium. Selon la présente invention, le précurseur réalise la co-précipitation de nickel, de cobalt et d'aluminium. Sous l'action d'une déchloration ultérieure, d'une élimination du calcium et d'une déshydratation, un matériau poreux ayant une faible densité après tassement est progressivement formé, ce qui facilite la diffusion d'une source de lithium pendant le processus de frittage ultérieur avec la source de lithium pour préparer un matériau d'électrode positive.
