Abstract

La présente invention concerne un matériau d'électrode positive stratifié pour une batterie au sodium-ion et son procédé de préparation. La formule chimique du matériau d'électrode positive stratifié pour une batterie au sodium-ion est Na<sub>x</sub>MnO<sub>2-a</sub>(MO<sub>4</sub>)<sub>a</sub>, où 0＜x ≤ 1 ; 0,01 ≤ a ≤ 0,2, et M représente un élément ou les deux parmi W ou Mo. Le procédé de préparation comprend : la préparation d'une solution de sel de manganèse et d'une solution de permanganate de potassium basique mélangée à un matériau d'élément M, le matériau d'élément M représentant un élément ou les deux parmi le molybdate et le tungstate ; l'ajout de la solution de permanganate de potassium basique à la solution de sel de manganèse et, une fois la réaction terminée, la réalisation d'une séparation solide-liquide pour obtenir un matériau solide ; et le lavage et le séchage du matériau solide, le mélange du matériau solide avec une source de sodium, puis le frittage de celui-ci pour obtenir un matériau d'électrode positive stratifié pour une batterie au sodium-ion. Le matériau d'électrode positive stratifié pour une batterie au sodium-ion de la présente invention améliore la structure de squelette du matériau en raison du dopage de l'élément tungstène ou molybdène, inhibe le changement de phase du matériau pendant le processus de charge et de décharge, et peut améliorer de manière significative la capacité spécifique, la performance de cycle et la capacité de vitesse du matériau.
