摘要
以石油焦为原料,将二氧化碳气体活化和苯气相沉积两种单一改性方法结合起来对其进行共改性处理制得锂离子二次电池炭负极材料。采用三电极体系,以200μA.cm-2电流进行恒流充放电测试电池容量。发现活化较短时间后进行沉积的共改性方法比单一改性方法更能明显提高电极性能。
Carbon anodes of lithium ion battery are made with petroleum coke by combined methods of gas activation and benzene de.position. Three electrode-system is used to measure the properties of anodes with the current density 200 μA · cm^-2,It is found that after activation for a short time,combined method can increase the battery＇s properties much better than single method.
