Abstract

La présente invention concerne un précurseur de matériau d'électrode positive NCA ayant une structure noyau-enveloppe, sa méthode de préparation et son utilisation. Le précurseur est une particule sphérique ou sphéroïde et est composé d'une enveloppe externe et d'un noyau interne. L'enveloppe externe a une formule chimique générale de Ni<sub>a</sub>Co<sub>b</sub>Al<sub>c</sub>(OH)<sub>2+c</sub>, où a + b + c = 1, 0,45 ≤ a ≤ 0,55, 0,15 ≤ b ≤ 0,25, et 0,25 ≤ c ≤ 0,35 ; le noyau interne a une formule chimique générale de Ni<sub>x</sub>Co<sub>y</sub>Al<sub>z</sub>(CO<sub>3</sub>)<sub>1-z</sub>(OH)<sub>3z</sub>, où x + y + z ＝ 1, 0,85 ≤ x ≤ 0,98, 0 ＜ y ≤ 0,15, et 0 ＜ z ≤ 0,15. Le noyau interne a une structure poreuse. Le noyau interne dans le précurseur de la présente invention a une teneur élevée en nickel et une structure poreuse, qui peut amortir efficacement le changement de volume provoqué par la charge et la décharge ultérieures du matériau d'électrode positive NCA. L'enveloppe externe est un matériau à faible teneur en nickel, ce qui atténue le changement de volume provoqué par la teneur élevée en nickel.
