Abstract
The present invention relates to a conducting material composition capable of forming an electrode in which at least two kinds of carbon based materials are contained in a uniformly dispersed state to enable a battery such as a lithium rechargeable battery having more improved electrical and lifetime characteristics to be provided, and a slurry composition for forming an electrode of a lithium rechargeable battery and a lithium rechargeable battery using the same. The conducting material composition contains: at least two kinds of conductive carbon-based materials selected from the group consisting of carbon nano tube, graphene, and carbon black; and a dispersant containing a plurality kinds of poly aromatic hydrocarbon oxides, wherein the dispersant contains poly aromatic hydrocarbon oxides having a molecular weight of 300 to 1000 at a content of 60 wt.% or more.
