Porous Sintered Superstructure with Interstitial Silicon for Use in Anodes for Lithium Batteries

Anodes for the lithium secondary batteries include a strong, electrically conductive, porous superstructure filled with a milled or melted interstitial material, such as nano-scaled silicon; the milled or melted interstitial material provides high lithiation capacity, and the superstructure provides durability and controls the anode's electromechanical expansion and contraction during the lithiation and de-lithiation cycle. Embodiments include porous superstructures comprised of silicon carbide, tungsten, and other materials, many of which offer capability of lithiating.
