Title (EN) LITHIUM-ION BATTERY AND NEGATIVE ELECTRODE MATERIAL THEREOF
(FR) BATTERIE AU LITHIUM-ION ET SON MATÉRIAU D'ÉLECTRODE NÉGATIVE
(ZH) 锂离子电池及其负极材料
Abstract:
(EN) Provided are a lithium-ion battery and a negative electrode material thereof. The negative electrode material of the lithium-ion battery comprises graphene and an amorphous carbon. The graphene has a graphitization degree of 90-96% and an average grain diameter D50 of 2-25 μm. The amorphous carbon has a graphitization degree of 65-80% and an average grain diameter D50 of 2-25 μm. In the present invention, graphene having a smaller grain diameter is mixed with an amorphous carbon, thereby obtaining a negative electrode material of a lithium-ion battery having balanced and superior kinetic performance, cycling performance and storage performance.
(FR) L'invention concerne une batterie au lithium-ion et son matériau d'électrode négative. Le matériau d'électrode négative de la batterie au lithium-ion comprend du graphène et un carbone amorphe. Le graphène a un degré de graphitisation de 90 à 96 % et un diamètre de grain moyen D50 de 2 à 25 µm. Le carbone amorphe a un degré de graphitisation de 65 à 80 % et un diamètre de grain moyen D50 de 2 à 25 µm. Dans la présente invention, du graphène ayant un diamètre de grain plus petit est mélangé avec un carbone amorphe, ce qui permet d'obtenir un matériau d'électrode négative d'une batterie au lithium-ion ayant des performances cinétiques équilibrées et supérieures, des performances de cyclage et des performances de stockage.
(ZH) 一种锂离子电池及其负极材料,锂离子电池负极材料包括石墨和无定形碳,其中,石墨的石墨化度为90~96%,平均粒径为D50为2~25μm;无定形碳的石墨化度为65~80%,平均粒径为D50为2~25μm。通过将粒径较小的石墨与无定形碳混合,所得锂离子电池负极材料具有平衡优异的动力学性能、循环性能和存储性能。
