摘　　要：将2200℃石墨化处理的纳米碳纤维作为锂离子电池的负极材料,对其充放电性能做了初步研究。结果表明:纳米碳纤维的循环性能良好,首次不可逆容量很大,这与纳米碳纤维的比表面积大及所用材料石墨化程度低有关。The carbon nanofiber(CNF) graphitized at 2 200?℃ was used as negative electrode active materials for Li-ion batteries. The charge/discharge property of the CNF was investigated . Results showed that the CNF had good cycle characteristics, but the irreversible capacity was high which was considered to be related to the high specific surface area and the low graphitized degree.
