Abstract

Sont décrits dans la présente invention un précurseur radial à base de nickel et son procédé de préparation. La forme globale du précurseur est une sphère secondaire formée par l'agglomération de grains cristallins primaires ; l'intérieur du précurseur comprend un noyau interne lâche et poreux d'une structure en forme de filet ; l'extérieur du précurseur est pourvu de grains cristallins primaires réguliers uniformes en forme de bande ; et les grains cristallins en forme de bande croissent vers l'extérieur perpendiculairement à la surface du noyau interne et sont agencés radialement et étroitement. La structure de précurseur fournie par la présente invention est plus appropriée pour un matériau d'électrode positive d'une alimentation électrique à forte puissance parce qu'une telle structure interne lâche forme plus facilement un espace en son centre au cours du processus de préparation du matériau d'électrode positive, de façon à permettre d'accroître une zone de contact entre une substance active et un électrolyte, à raccourcir un trajet de transmission d'ions Li dans le matériau au moyen d'une combinaison de la structure creuse et des grains cristallins radiaux, à atténuer une contrainte de déformation provoquée par la dilatation et la contraction du volume des grains sur une macrostructure et à améliorer les performances de cycle d'un matériau de batterie.
