Abstract
Silicon slurry for anode active materials of secondary batteries is provided. The silicon slurry includes silicon particles and a dispersion medium. The silicon slurry satisfies dispersion conditions of 1≦D90/D50≦2.5 and 2 nm<D50<180 nm, where D90 denotes an average diameter of the silicon particles at 90% of cumulative particle size distribution, and D50 denotes an average diameter of the silicon particles at 50% of cumulative particle size distribution.
