Abstract: Similar amount of carbon with three different types of morphologies, i.e. smooth pyrolytic carbon (SPC), granular pyrolytic carbon (GPC) and carbon nanofiber (CNF) was coated on the natural graphite (NG) spheres in a fluidized bed by chemical vapor deposition (CVD) from acetylene. The effect of carbon-coating morphologies on the electrochemical performance of NG spheres were studied, the results show that: PC is more effective in improving the first coulombic efficiency (CE); both GPC and CNF can improve the cyclability, however, GPC improves the first CE whereas CNF decreases the first CE.
