Abstract
A porous reduced silica fiber material has a diameter of about 0.1 to about 20 microns and a surface area of about 5 m2/g to about 400 m2/g. The porous reduced fiber material may be used to form an electrode having a high capacity and improved cycle life over comparable commercial silicon electrodes.
