ANODE INCLUDING GRAPHITE AND SILICON-BASED MATERIAL HAVING DIFFERENT DIAMETERS AND LITHIUM SECONDARY BATTERY INCLUDING THE SAME

The present disclosure relates to an anode for a lithium secondary battery, wherein an anode material layer is formed on at least one surface of an anode current collector, andthe anode material layer includes large-particle graphite, a small-particle silicon-based material, fine-particle graphite, and carbon nanotube, and satisfies the following conditions 1 to 3:[Condition 1] Average diameter D50 of the large-particle graphite (D1): 1 to 50 µm[Condition 2] Average diameter D50 of the small-particle silicon-based material (D2): 0.155D1 to 0.414D1[Condition 3] Average diameter D50 of the fine-particle graphite (D3): 0.155D1 to 0.414D1, or 0.155D2 to 0.414D2.
