Preparation of Anode Material for Lithium Secondary Battery using Pitch-coated Graphite Residue Compounds KCI 등재
The properties and electrochemical characteristics of anode material using pitch-coated graphite residue compounds by heat-treatment at 600℃ for 1 hour were investigated. The distance of layers of pitch-coated graphite residual compounds was 3.3539 a, 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.
