In order to investigate the structure and properties of the carbon materials used for the negative electrodes in lithium-ion batteries, the X-ray diffraction (XRD) and nitrogen adsorption-desorption techniques were used to study the structures of the materials. The results showed that the capacity of the carbon materials was proportional to the spacing distance to some extent, and was related to the specific surface area; the increase of mesopores was beneficial to the increase of the capacity of carbon materials.
