1. A battery slurry additive comprising:
a plurality of Si-based nanoscale scaffolds disposed on particles of a carbon-based powder substrate comprising carbon black or graphite and forming a porous network,
wherein the particles of the carbon-based powder substrate are between 5 microns and 50 microns,
wherein the plurality of Si-based nanoscale scaffolds have a core-shell structure,
wherein the plurality of Si-based nanoscale scaffolds comprise nanowires with at least one cross-sectional dimension less than 100 nm,
wherein said porous network comprises mesopores and macropores, and
wherein said porous network can accommodate volume changes associated with lithiation and delithiation during repeated charge/discharge cycles of a battery anode electrode.
