摘要
采用碳纳米管(CNTs)作为锂离子电池负极材料的添加剂,测试了负极材料的电化学性能。结果表明:添加2%(质量比)的CNTs,使负极材料的首次充、放电容量分别提高29.4 mAh/g和45.1 mAh/g,经20次循环,容量未见衰减。这是由于CNTs具有较大的比表面积和较高的储锂能力。
The electrochemical performance of the anode materials as carbon nanotubes （CN TS） used as additive for Li-ion battery anode was evaluated. The results showed that the initial charge and discharge capacities of anode with 2%（wt%） CNTs increased by 29.4 mAk/g and 45.1 mAh/g, respectively. The capacities did not decrease after 20 cycles, due to the large specific surface area and high lithium intercalation capacity of CNTs.
