以具有气相碳化形式的精制煤焦油沉积碳为壳层材料、人造石墨（ＡＧ）及中间相石墨微球（２８００℃）为核材料制备了核壳结构的碳及碳电极．核壳结构碳及核壳结构碳电极的充放电研究表明碳负极的稳定充放电容量及首次充放电效率都得到了较大的改善，循环伏安研究表明在０．７Ｖ（ｖｓＬｉ＋／Ｌｉ）左右用于形成碳电极表面钝化膜的溶剂的还原分解峰显著减小，显示了核壳结构碳材料电极对电极表面钝化膜的影响作用，Ｘ射线衍射研究揭示了石墨及石墨电极上的无定形碳壳层的存在
The carbon powders and film electrode with core shell structure were prepared by carbonization in gas state with using refined coal as shell material and Artificial Graphite and Mesocarbon Microbeads (2 800 ℃) graphite as core material. Galvanostatic charge/discharge measurement showed that both steady charge/discharge capacity and first charge/discharge efficiency were improved. Cyclic voltammetry indicated that the peak at about 0.7 V vs. Li +/Li characteristic of decomposition of electrolyte got weakened, and a more compact film was formed. X ray diffraction measurement suggested the existence of amorphous carbon shell on the carbon powders and carbon film.
