| 摘 要： | 利用循环伏安法对锂在苯碳黑中的插入过程进行了研究。结果表明,锂在苯碳黑中的首次插入过程伴随着一些不可逆反应,这些不可逆反应是由于电解质溶液中的溶剂化离子的插入引起的。在碳表面也存在的不可逆反应。随着具有石墨结构成分的增加,在碳中有了明显的锂插入反应。经1000℃以上温度处理过的碳黑锂的迁出电位在0.1左右,从而能代替锂作二次锂电池阳极材料。 |

| Abstract: | The intercalation of lithium into benzene carbon black was investigated in nonaqueous solution by cycling voltammetric methods. The results showed that the exist of several irreversible reactions during the first cathodic scanning was due to the decompositions and intercalations of the solvents in the electrolyte. By increasing the content of graphitization region in the benzene carbon black, the intercalation and deintercalation of lithium could occur at about 0.1 V vs lithium and make it possible to change the lithium in the lithium secondary batteries with this kind of carbon. |
