Graphite intercalation compounds , as a important kind of compounds , not only retain the good original graphitic properties , but also are evoked to show some fine performances 摘要石墨层间化合物是一种重要的化合物,它不仅保留了石墨原有的优良特性,还被激发出一些优异的物化性能。
Factor contributing to this problem is that the metal cobalt used as the cementing phase easily causes diffusion and dissolution of carbon , promotes graphite growth and inhibits diamond nucleation and growth in the course of competitive growth between diamond and graphitic carbon 其原因是在沉积过程中,基体中所含的钴会引起碳的溶解和扩散,从而导致金刚石成核密度的降低和石墨的形成。
As the temperature and the soak time increasing , crystallite size , graphitic degree and average particle size of the graphite increase , while specific surface area decreases . the electrochemical performance of modified graphite is improved with the change in structure and surface characteristics 结果表明,随着热处理温度的升高和恒温时间的延长,石墨材料的石墨化度、石墨微晶尺寸l _ c及l _ a逐渐增大,比表面积减小,平均粒径增大,充放电性能得到改善。
