碳纤维制品结构分析及其用作锂离子电池负极材料性能研究

摘要

通过x-射线衍射（XRD）和N2-BET法对材料结构进行分析，研究了其结构及用作锂离子电池负极材料的性能。结果表明，在一定范围内碳材料的容量与其层间距成正比关系；比表面积的大小与材料的容量有一定的关系；中孔率的提高有利于碳材料容量的增加。%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.
