将两种纳米碳管材料作为锂离子电池负极材料，对其嵌锂行为进行了初步研究.两种材料的首次不可逆容量都很大，这被认为是与电解质在电极材料表面的电化学还原生成的SEI膜有关.对于两种纳米碳管而言，nmcl的不可逆容量远远大于nmc2的不可逆容量，其主要原因是由于nmc1比nmc2的比表面积大.

Two kinds of carbon nanotubes were adopted as negative electrode active materials of lithium ion batteries and the mechanism of lithium intercalation was studied.The irreversible capacity of both two materials is high,which is considered to be related to the formation of SEI on the surface of the elctrode.The irreversible capacity of nmcl is much higher than that of nmc2 because the specific area of nmcl is higher than that of nmc2.
