| 摘 要： | 通过研究在不同的循环次数时无定形碳材料的电子自旋共抓信号的强度变化及形态结构的变化，得出了容量衰减的机理。该机理表明容量的衰减是由于包在反复插入和脱出过程中，破坏了无定形碳材料的结构所致。

| Abstract: | Through investigation of changes of the intensity of electron spinning signal and morphology of amorphous carbon materials at different cycle numbers, mechanism for capacity fading was obtained. The mechanism showed that the amorphous carbon structure could be destroyed during the repeating intercalation and removal of lithium, therefore the reversible capacity faded with cycling. |
