摘要： Embodiments of the present disclosure pertain to porous silicon particulates and anode materials that contain them. In some embodiments, each of the porous silicon particulates include a plurality of macropores, mesopores and micropores such that the micropores and mesopores are within the macropores. The porous silicon particulates also contain: a coating associated with the porous silicon particulates; and a binding material associated with the porous silicon particulates. The binding material can include binders, carbon materials, polymers, metals, additives, carbohydrates, and combinations thereof.
