Abstract

A method for forming a porous silicon material can include forming a mixture of silicon, carbon, and an etchant element, solidifying the mixture, removing the etchant element to form pores within the silicon material. The porous silicon material can include a distribution of pores with an average pore diameter between about 10 nm and 500 nm, wherein the silicon particle comprises a silicon carbon composite comprising 1-5% carbon by mass, 1-5% oxygen by mass, and 90-98% silicon by mass.
