Abstract

L'invention concerne un précurseur ternaire à haute densité après tassement et sa méthode de préparation. La méthode comprend les étapes suivantes consistant à : (1) ajouter une émulsion de dioxyde de silicium dans une solution de substrat alcalin pour obtenir une solution mixte ; (2) ajouter une solution mixte de sel de nickel-cobalt-manganèse, un précipitant, un agent complexant et un tensioactif ; (3) réaliser une séparation solide-liquide pour obtenir un matériau solide, et sécher et broyer pour obtenir un matériau broyé ; (4) mélanger le matériau broyé avec la solution de substrat alcalin et le tensioactif ; (5) répéter l'étape (2) ; et (6) réaliser une séparation solide-liquide pour obtenir un matériau solide, et laver et sécher le matériau solide pour obtenir le précurseur ternaire à haute densité après tassement. La particule de précurseur préparée selon la méthode a une densité après tassement plus élevée, et peut fournir une excellente performance de cycle pour le matériau d'électrode positive.
