Abstract
Highly porous synergistic combinations of silicon and carbon materials are provided, along with articles that incorporate such materials and processes for producing the materials. 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 including solid state batteries.
