Abstract

L'invention concerne un précurseur de matériau d'électrode positive, son procédé de préparation et son application. La formule chimique du précurseur de matériau d'électrode positive est nixco ymnz(oh) 2, dans laquelle 0,2 = x = 1, 0 = y = 0,5, 0 = z = 0,6, 0,8 = x + y + z = 1 ; le précurseur de matériau d'électrode positive étant en forme de feuille empilée, et le coefficient d'élargissement de taille de particule du précurseur de matériau d'électrode positive étant k, et k = 0,85. En utilisant un procédé de cristallisation régulée et en combinaison avec un modèle théorique de nucléation et de croissance de lamer, le procédé de préparation d'un précurseur peut être efficacement régulé et ajusté ; en outre, le précurseur préparé présente les caractéristiques morphologiques de distribution de taille de particule concentrée et une proportion élevée de plans {010} cristallins actifs. Dans le taux de grossissement de 20c, la vitesse de rétention de capacité peut atteindre 91,33 %.
