Electrochemical characteristics of carbon (CFR, MCMB, etc) as anode material of the lithium secondary batteries were studied by the galvanostatic charge/discharge with various current densities and electrolytes. In the case of CFR and MCMB, LiAsF6/PC electrolytic solution was the best among tested electrolytes in the condition of current density of 1mA/10mg and potential range of 0 similar to 1.5V vs. Li/Li+. And its charge/discharge characteristics were good in current density of 1mA/10mg.
