1. A method of forming a lithium-ion battery (LIB)
component, comprising: providing at least one substrate structure; and
electrochemically depositing a plurality of nanostructures directly onto one or more surfaces of the at least one substrate structure, wherein the nanostructures are formed via electrochemical deposition without a growth template, and the nanostructures are comprised of crystalline Si and are substantially free of amorphous Si or polycrystalline Si upon formation.
