Preparation of Anode Material for Lithium Secondary Battery using Pitch-coated Graphite Residue Compounds Ko, Young-Shin; Oh, Won-Chun;
The properties and electrochemical characteristics of anode material using pitch-coated graphite residue compounds by heat-treatment at for 1 hour were investigated. The distance of layers of pitch-coated graphite residual compounds was 3.3539 , which was as same as that of graphite. Its electrochemical and charge discharge characteristics were tested according to different four types of carbon material, natural graphite, pitch-coated graphite, amorphous graphite and pitch-coated graphite residual compounds, respectively. So it was shown the best charge-discharge characteristics in all of the samples. For the electrochemical and charge-discharge characteristics, although pitch-coated graphite residual compounds had different carbon contents 70% and 80%, these two samples were shown good electrochemical and charge-discharge characteristics.
