Abstract

La présente invention concerne une méthode de préparation d'un précurseur de matériau d'électrode positive ayant un grand canal, et son application. La méthode comprend : le mélange d'une solution aqueuse d'hexanitrocobaltate de sodium, d'une solution de sel mixte de nickel-manganèse, d'une solution d'acide oxalique et d'ammoniac aqueux pour réaction ; la calcination d'un matériau solide ; et le trempage du matériau calciné dans de l'eau pour obtenir un précurseur de matériau d'électrode positive ayant un grand canal. Selon la présente invention, le nickel-cobalt-manganèse et le sodium-ammonium sont co-précipités et frittés, puis le sodium-ammonium est éliminé ; et étant donné que le rayon des ions sodium est supérieur au rayon des ions lithium, un grand canal ionique est laissé dans une structure de précurseur nickel-cobalt-manganèse, ce qui facilite la désintercalation des ions lithium d'un matériau d'électrode positive fritté chimiquement, élargit un canal de diffusion d'ions lithium, et améliore remarquablement la capacité de débit et les performances de cycle du matériau.
