Conductive Material, Electrode Including the Same, and Lithium Secondary Battery Including the Electrode

Abstract

A conductive material includes a conductivity performance index PC ranging from 0.03 to 8.10. The conductivity performance index is defined by an aspect ratio, a powder resistance, a packing density when the powder resistance is measured, BET specific surface area, and volume cumulative average particle diameter D50. Such a conductive material is capable of improving the performance of an electrode by utilizing physical properties which may be related to resistance characteristics and lifespan characteristics of the electrode, such as the conductive material forming a conductive network connection path between active material particles and within an active material particle in the electrode, being arranged in pores, and being arranged on the surface of an active material.
