Abstract
A method for manufacturing porous silicon can include reducing unpurified silica in the presence of a reducing agent to prepare a porous silicon material. The method of manufacture can optionally include purifying a silica, exposing the silica to reaction modifiers, purifying the mixture of the silica and reaction modifiers, comminuting the silica, purifying the silicon, coating the silicon, post-processing the silicon, and/or any suitable steps.
