Publication number: 20160344016Abstract: In some embodiments, the present invention provides methods of preparing porous silicon films and particles by: (1) etching a silicon material by exposure of the silicon material to a constant current density in a solution (e.g., hydrofluoric acid solution) to produce a porous silicon film over a substrate; and (2) separating the porous silicon film from the substrate by gradually increasing the electric current density in sequential increments. The methods of the present invention may also include a step of associating the porous silicon film with a binding material, such as polyacrylonitrile (PAN).
