Abstract

La présente divulgation se rapporte au domaine technique des matériaux d'électrode positive, et concerne un matériau d'électrode positive et son procédé de préparation, ainsi qu'une plaque d'électrode positive et une batterie. Le procédé de préparation comprend les étapes suivantes : l'application sur la surface d'hydroxyde de nickel sphérique d'un composé de lithium, d'un composé de cobalt divalent, d'un composé de cobalt trivalent et d'un composé facultatif M, puis la réalisation d'un frittage primaire sur le matériau appliqué dans des conditions aérobies, la teneur molaire du composé de cobalt trivalent dans le composé de cobalt étant de 50 % à 85 %. Dans le procédé de préparation, la solution de revêtement d'hydroxyde de nickel sphérique avec un composé de cobalt divalent et un composé de cobalt trivalent ensemble, puis de frittage, est utilisée, de sorte que non seulement une couche de revêtement de cobaltate de lithium uniforme peut être formée sur la surface des particules de nickelate de lithium, mais un dopage au cobalt peut être formé à l'intérieur des particules de nickelate de lithium, ce qui permet d'inhiber efficacement la transition de phase du matériau et les réactions secondaires avec l'électrolyte, tout en garantissant la très haute teneur en nickel du matériau, améliorant ainsi de manière significative les performances de vitesse, la stabilité de cycle et les avantages de capacité du matériau.
