Prepatation of Anode Material for Lithium Secondary Battery using Pitch-coated Graphite Residue Compounds

다국어 초록 (Multilingual Abstract)

The properties and electrochemical characteristics of anode material using pitch-coated graphite residue compoundsby heat-treatment at 600oC for 1 hour were investigated. The distance of layers of pitch-coated graphite residual com-pounds was 3.3539 , which was as same as that of graphite. Its electrochemical and charge-discharge characteristicswere tested according to different four types of carbon material, natural graphite, pitch-coated graphite, amorphousgraphite and pitch-coated graphite residual compounds, respectively. So it was shown the best charge-discharge charac-teristics in all of the samples. For the electrochemical and charge-discharge characteristics, although pitch-coatedgraphite residual compounds had different carbon contents 70% and 80%, these two samples were shown good electro-chemical and charge-discharge characteristics.
