| الوصف: | Graphite is an important active material for lithium ion battery anode. In the present paper, a kind of graphitized MCMB (MCMB-6-28) was oxidized at 600 or 700 °C, and the effects of the oxidation were investigated by cyclic voltammetry (CV) method, electrochemical impedance spectroscopy (EIS), and rectangular potential technique. It was found that the specific surface area of the electrode made of the graphite can be increased notably by the oxidative treatment. Meanwhile, after oxidation, the electrochemical impedance of the graphite electrode is reduced, and the reaction reversibility is improved. ; We are grateful to Jinkyu Hong, Jiheon Ryu and Taeahn Kim for their help during the work.
