Abstract

L'invention concerne un matériau d'électrode négative et une batterie. Le matériau d'électrode négative comprend du graphite, la surface et/ou l'intérieur du graphite ayant des pores, et le matériau d'électrode négative ayant un volume des pores de V cm<sup>3</sup>/kg, une densité réelle de D g/cm<sup>3</sup>, une surface spécifique de S m<sup>2</sup>/g, et un degré de graphitisation de G %, où 0,7 ≤ V*S/D ≤ 3,95, et 89 ≤ G ≤ 93. Le matériau d'électrode négative et la batterie peuvent améliorer la capacité de vitesse et les performances de cycle d'un matériau d'électrode négative en graphite sous un courant à haut débit.
