Abstract

La présente invention divulgue un procédé de préparation d'un précurseur de matériau d'électrode positive revêtu à base d'étain. Le procédé comprend les étapes suivantes consistant à : (1) mélanger un hydroxyde de nickel-cobalt-manganèse avec une solution contenant un ion carbonate et un ion soufre ; (2) ajouter une solution de source d'étain à la solution mélangée de l'étape (1), faire réagir celle-ci, et réaliser une séparation solide-liquide pour obtenir un produit solide ; et (3) tremper le produit solide obtenu à l'étape (2) dans une solution de persulfure, réaliser une séparation solide-liquide, puis réaliser un lavage et un séchage pour obtenir le précurseur de matériau d'électrode positive. Un matériau d'électrode positive préparé à partir du précurseur de matériau d'électrode positive revêtu à base d'étain préparé par le procédé de préparation présente une bonne conductivité et un bon taux de migration d'ions lithium, de telle sorte que le matériau d'électrode positive est assuré d'avoir une performance électrochimique relativement bonne.
