Abstract
The formation of amorphous silicon for use in, for example, lithium-ion batteries is disclosed. The process can include milling a plurality of silicon nanocrystals having an average particle diameter and a percent crystallinity greater than about 60%, in a unit designed to reduce the average particle diameter to the same or a larger size, thereby forming a plurality of amorphous silicon nanoparticles having about the same average particle diameter as the silicon nanocrystals and a percent crystallinity of less than about 50%.
