将碳纳米管部分掺入石墨材料中用作锂离子电池电极材料，二者形成许多纳米级微孔，为锂离子提供了更多的嵌入脱出空间，使可逆容量得以提高，而且碳纳米管可以起到桥梁的作用，增强了材料的导电性，避免了石墨在充放电过程中产生孤岛效应.结果表明，这种掺杂材料的首次可逆容量为341.8 mA·h/g，循环10次后可逆容量保持率为94.5％.
Carbon nanotubes and graphite were mixed and used as anode material for lithium ion bat-tery. A great many of nano-scale pores were formed between carbon nanotubes and graphite, improv-ing the charge-discharge capacity of the mixture. Moreover,as a bridge, the carbon nanotubes couldimprove the property of electric conduction and avoid the effect of isolated island during the lithium in-tercalation and e-intercalation. The reversible capacity of the anode materials on first cycle was341.8 mA· h/g, and maintained at 94.5％ after 10 cycles. The charge-discharge behavior of themixed materials was better than that of the single carbon nanotubes or graphite.
