CONDUCTIVE COMPOSITION, SLURRY COMPOSITION FOR FORMING ELECTRODE OF LITHIUM SECONDARY BATTERY USING SAME, AND LITHIUM SECONDARY BATTERY

摘要

The present invention relates to a conductive composition which enables an electrode comprising two or more carbon-based materials in a uniformly dispersed state to be provided, thereby enabling a battery, such as a lithium secondary battery, having more improved electric and lifetime characteristics to be provided; a slurry composition for forming an electrode of a lithium secondary battery using the same; and a lithium secondary battery. The conductive composition comprises two or more carbon-based materials selected from a group consisting of carbon nanotubes, graphene, and carbon black; and a dispersing agent comprising a plurality of types of polyaromatic hydrocarbon oxides, the content of polyaromatic hydrocarbon oxides having a molecular weight of 300-1000 being 60 wt% or more.
