METHOD OF PRODUCING NEGATIVE ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERY, NEGATIVE ELECTRODE FOR SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY INCLUDING THE SAME

A negative electrode for a secondary battery including: a negative electrode current collector; and a negative electrode active material layer present on the negative electrode current collector. The negative electrode active material layer includes a negative electrode active material, wherein the negative electrode active material for a secondary battery includes natural graphite, and has a sphericity of 0.58 to 1, a tap density of 1.08 g/cc to 1.32 g/cc, and D−Dof 16 μm to 19 μm, wherein D−Dis a difference between a maximum particle diameter Dand a minimum particle diameter Din a particle size distribution.
