Abstract

La présente divulgation concerne un matériau d'électrode négative et une batterie. Le matériau d'électrode négative comprend du graphite. Des pores sont formés à l'intérieur et/ou sur la surface du graphite, et le volume de pores du matériau d'électrode négative est V(cm<sup>3</sup>/kg), sa surface spécifique est S(m <sup>2</sup>/g), et sa masse volumique après tassement est T(g/cc), où 2 ≦ V <sup>*</sup>S/T ≦ 10. En construisant la relation de rapport entre la surface spécifique du matériau d'électrode négative, le volume de pores et la masse volumique de tassement du matériau d'électrode négative, la condition de distribution global de défauts tels que des canaux de pores, des réseaux et des microfissures dans des particules de graphite peut être représentée, et dans la plage limitée précédente, il indique que lorsque le matériau d'électrode négative est transformé en une électrode et appliqué à une batterie, les défauts dans le matériau d'électrode négative sont répartis uniformément, et une structure de défaut uniformément distribuée peut réduire l'expansion générée dans un processus de charge et de décharge du matériau d'électrode négative en graphite, et améliorer les performances électriques et les performances de traitement.
