A negative electrode of a lithium secondary battery having a mixture layer containing graphite particles and an organic binder on a current collector, wherein the diffraction intensity ratio (002)/(110) of the mixture layer measured by X-ray diffraction is not higher than 500, and a lithium secondary battery having that negative electrode and a positive electrode containing a lithium compound. Since the quick charge/discharge characteristics and the cycle characteristics do not deteriorate significantly when the negative electrode density of the lithium secondary battery is increased, a high- capacity lithium secondary battery having an enhanced energy density per volume of secondary battery can be provided.

La présente invention a trait à une électrode négative pour un accumulateur au lithium comportant une couche de mélange contenant des particules de graphite et un liant organique sur un collecteur de courant, dans laquelle le rapport d'intensité de diffraction (002)/(110) de la couche de mélange mesurée par diffraction de rayons X est égale ou inférieure à 500, et un accumulateur au lithium comportant cette électrode négative et une électrode positive contenant un composé de lithium. Etant donné que les caractéristiques de charge/décharge rapide et les caractéristiques de cycle ne se détériorent pas de manière significative lors de l'accroissement de la densité d'électrode négative de l'accumulateur au lithium, il est possible d'obtenir un accumulateur au lithium haute capacité présentant une densité d'énergie améliorée par volume d'un accumulateur au lithium.
