摘要
将准一维结构的多壁碳纳米管和零维结构的导电乙炔炭黑均匀分散制备复合导电剂,并将其加入商品化锂离子电池负极材料中,考察复合导电剂对负极电化学性能的影响。结果表明,该碳纳米管复合导电剂可有效提高电极材料的首次库仑效率和循环寿命。
Carbon nanotube composite made of quasi- one- dimension multi- walled carbon nanotubes (MWNTs) and zero- dimension carbon black(CB) was used as anode conductive additives in lithium ion batteries. Results show that the composite improves the first cycle columbic efficiency and cycle life of anode materials effectively.
