Abstract
Silicon-silica hybrid materials made by metallothermal reduction from silica and methods of producing such compositions are provided. The compositions have novel properties and provide significant improvements in Coulombic efficiency, dilithiation capacity, and cycle life when used as anode materials in lithium battery cells.
