Abstract

The invention relates to a method for size-reducing silicon, wherein a mixture containing a suspension containing silicon to be size-reduced and silicon grinding media is set in motion in the grinding space of a grinding media mill. The size-reduced silicon is used as the active material in the anode of a lithium-ion battery.
