Abstract
A slurry composition for a secondary battery electrode includes a conductive material including a linear carbon material and a point-type carbon material, a dispersant, and an organic solvent. A measurement of a particle size distribution of the conductive material in the slurry composition, measured by a laser diffraction particle size analyzer, exhibits a first peak and a second peak within specific ranges.

A slurry composition for a secondary battery electrode, the composition comprising:
- a conductive material containing a linear carbon material and a point-like carbon material;
- a dispersant;
- and
- an organic solvent,
- wherein a measurement of a particle size distribution of the conductive material in the slurry composition, measured by a laser diffraction particle size analyzer, exhibits a first peak and a second peak,
- wherein the first peak has a maximum peak value at a particle size range equal to or greater than about 0.01 μm and equal to or less than about 1.0 μm, and
- wherein the second peak has a maximum peak value at a particle size range equal to or greater than about 1.0 μm and equal to or less than about 20.0 μm.
