Abstract
◎ Plasma carbon and nitrogen-doped carbons are prepared by plasma pyrolysis method and employed as anode active materials for Li-ion batteries. ◎ Based on the TEM analysis, plasma carbon and nitrogen-doped carbons have similar particle size distributions ranging from 10 to 70 nm. Thus, nitrogen doping does not seem to affect the particle size variation. ◎ Raman spectra show that the crystallinity of nitrogen-doped carbon decreased with increasing the doping concentration. However, the ID/IG value decreased when the N2/C2H2 ratio was higher than 0.15, suggesting that the degree of crystallinity increased again. ◎ The best electrochemical performance was observed for nitrogen-doped carbon (PCN10). It shows the highest reversible capacities up to a relatively higher current density of 500 mA/g.
