Abstract
La présente invention concerne un précurseur de matériau de cathode, un matériau de cathode monocristallin et leur méthode de préparation, ainsi qu'une batterie lithium-ion. La formule chimique générale du matériau de cathode monocristallin est LixNiaCobMncNdO2, où 0.98≤x≤1.1, 0.50≤a≤0.98, 0<b≤0.20, 0<c≤0.30, 0≤d≤0.10, a+b+c+d=1, et N comprend au moins un des éléments suivants : Al, Ti, Zr, Mg, Sr, Ba, Ca, Nb, W, Sb, Ta, Sn ou Y ; un écart type de la teneur massique de chaque élément de Ni, Co et Mn dans le matériau de cathode monocristallin est ≤ 0.03 ; et la contrainte de réseau est ε < 0.2 %. Selon le matériau de cathode monocristallin fourni dans cette invention, la faible contrainte de réseau permet de réduire les barrières de diusion des ions lithium entre les cristaux, ce qui permet au matériau de présenter une faible résistance à la décharge (DCR) et de bonnes performances en termes de vitesse ; la génération de microfissures peut également être inhibée, améliorant ainsi les performances cycliques du matériau.
