Abstract

Matériau d'électrode négative et son procédé de préparation, et batterie au lithium-ion. Le matériau d'électrode négative comprend un agrégat. L'agrégat comprend une substance active, un matériau carboné et un élément dopant. Le matériau carboné est représenté dans le diagramme Raman obtenu par spectroscopie Raman à l'aide d'une source de lumière de mesure à une longueur d'onde de 532 nm. Une bande G est observée à 1 530 cm<sup>-1</sup> jusqu'à 1 630 cm<sup>-1</sup>, une bande D est observée à 1 280 cm<sup>-1</sup> jusqu'à 1 380 cm<sup>-1</sup>, et le rapport I<sub>D</sub>/I<sub>G</sub> de l'intensité de pic I<sub>D</sub> de la bande D à l'intensité de pic I<sub>G</sub> de la bande G est de 1-2,5. La première efficacité temporelle du matériau d'électrode négative est considérablement améliorée, et la stabilité des performances de cycle est considérablement améliorée.
