Abstract

An anode composition according to an embodiment of the present invention comprises a silicon-based active material and a carbon-based active material, and simultaneously satisfies an optimal sphericity ratio represented by formula (1) and an optimal particle diameter ratio represented by formula (2). Formula (1): 0.7 ≤ X1/Y1 ≤ 1.5 Formula (2): 0.08 ≤ X2/Y2 ≤ 0.5. In formula (1), X1 denotes the sphericity of the silicon-based active material, and Y1 denotes the sphericity of the carbon-based active material, and in formula (2), X2 denotes an average particle diameter (D50) of the silicon-based active material, and Y2 denotes an average particle diameter (D50) of the carbon-based active material.
