锂离子电池碳纳米管负极材料储锂性能研究

Electrochemical performance of carbon nanotubes as anode materials for lithium ion battery

将碳纳米管用于锂离子电池负极材料,用循环伏安及充放电实验研究了电极的性能。结果表明,碳纳米管用作锂离子电池负极,具有较高的储锂容量,首次放电容量达560mAh/g,但首次不可逆容量损失也大,高达430mAh/g。经过第1次充放电的容量损失后,随后各次的容量损失很小,碳纳米管的循环性能趋于稳定。

Carbon nanotubes（CNTs）, as anode materials for lithium-ion batteries, their performances were studied with cyclic voltammetry and charging-discharge experiments. The results showed that CNTs had high lithium storage capacity as anode. Its initial discharge specific capacity was 560mAh/g but its first irreversible capacity loss were also found high at 430mAh/g. Subsequently, the capacity loss little after first, Cycle performance of CNTs tends to be stable.
