Abstract

La présente invention se rapporte au domaine technique de la synthèse de matériaux d'électrode positive. L'invention concerne un procédé de revêtement pour un matériau d'électrode positive d'oxyde de lithium-nickel-cobalt-manganèse. La présente invention concerne un procédé de revêtement pour un matériau d'électrode positive d'oxyde de lithium-nickel-cobalt-manganèse, lequel procédé comprend les étapes suivantes : (1) mélanger un matériau d'électrode positive d'oxyde de lithium-nickel-cobalt-manganèse avec une solution de permanganate de potassium, et introduire une oléfine sur celui-ci ; et (2) après que la réaction est terminée, sécher et calciner celui-ci pour obtenir un matériau d'électrode positive d'oxyde de lithium-nickel-cobalt-manganèse revêtu de dioxyde de manganèse ; le nombre d'atomes de carbone dans l'oléfine étant inférieur ou égal à 10, et le nombre de doubles liaisons carbone-carbone dans l'oléfine étant de 1. Dans le procédé de revêtement pour un matériau d'électrode positive d'oxyde de lithium-nickel-cobalt-manganèse selon la présente invention, au moyen du mélange du matériau d'électrode positive d'oxyde de lithium-nickel-cobalt-manganèse avec la solution de permanganate de potassium, et l'introduction d'oléfine dans celui-ci, un revêtement directionnel sur des défauts de surface est obtenu, sans avoir besoin de générer une couche de revêtement sur-épaisse. C'est-à-dire qu'une solution électrolytique peut être empêchée d'être soumise à une réaction secondaire avec le matériau d'électrode positive par l'intermédiaire des défauts de surface.
