Negative electrode active material for lithium secondary battery, method of manufacturing same, and lithium secondary battery comprising same

Abstract

The present embodiments relate to a negative electrode active material, a method for manufacturing the same, a negative electrode comprising the same, and a lithium secondary battery comprising the same. The negative electrode active material includes a core portion comprising at least one coarse graphite particle having an average particle diameter (D50) ranging from 5 to 20 μm and at least one fine graphite particle having an average particle diameter (D50) of less than 5 μm, wherein the fine graphite particles account for from 5 wt % to 30 wt % based on the total weight of the coarse graphite particles and the fine graphite particles.
