Abstract

The present invention relates to a conducting material composition which is allowed to provide an electrode having a higher content of uniformly dispersed carbon nanotubes, thereby providing a lithium rechargeable batteryelectrode having more improved electrical characteristics and life characteristics, a slurry composition for forming a lithium rechargeable batteryelectrode using the same, and a lithium rechargeable battery. The conducting material composition includes carbon nanotube; and a dispersing agent including a plurality of polyaromatic hydrocarbon oxides, in which the dispersing agent contains the polyaromatic hydrocarbon oxides having a molecular weight of 300 to 1000 in an amount of 60% by weight or more.
