碳化硅衍生碳/球形天然石墨复合材料的制备及其结构调控
Preparation and Structure Regulation of Silicon Carbide-Derived Carbon/Spherical Natural Graphite Composites
摘要
Abstract
To meet the requirements of the energy storage materials for high energy density and high power density, porous silicon carbide/derived carbon-spherical natural graphite (SiC-CDCs@NG) composites were prepared. The composites were composed of tailored porous carbide-derived carbon and graphitized carbon with excel ent conductivity and a high energy storage capacity. The composition, structure, morphology, pore structure, and specific surface area of the composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, and N2 adsorption/desorption analysis. The composites exhibited a high and adjustable specific surface area and micro-pore volume, with a micro-pore size of between 0.5 and 0.7 nm. Varying the molar ratio of NG and Si al owed optimization of the micro-pore volume, pore size distribution, specific surface area, and composition and content of the CDCs shel and NG core.关键词
