摘要： A cathode active material for an all-solid-state battery including colloidal silica, a cathode active material, and a manufacturing method thereof are disclosed. It may be possible to achieve an enhancement in dispersion in a sulfide-based all-solid-state battery by controlling powder properties while reducing interfacial resistance between an electrolyte and a cathode active material of the sulfide-based all-solid-state battery.
