Preparation of Lithium ion battery anode synthesized by petroleum residue |
| 초록 |
To enhance electrochemical performances, we have performed the surface modification of pitch based carbon by the chemical activation with KOH. The experimental method was optimized by proceeding various experiment parameters such as molar concentration of KOH solution and stirring time. In this study, the effect of activated solution malar ratio and stirring time on electrochemical performances was investigated. The prepared modified carbon was analyzed by FE-SEM and BET. Also the electrochemical performances of carbon as the anode were investigated by rate capability, cyclic voltammetry and electrochemical impedance tests. The half-cell using modified carbon (KOH 7M 2h stirring) has better electrochemical properties than that of other composition anode materials. Also, modified carbon anode appeared initial columbic efficiency and the retention rate capability. It is found that prepared carbon anode showed improved cycling and rate capacity performance. |
