ORDERED NANO-POROUS CARBON COATING ON SILICON OR SILICON/GRAPHENE COMPOSITES AS LITHIUM ION BATTERY ANODE MATERIALS

The present invention provides high specific capacity composite anode materials of silicon and carbon with stable charge/discharge cycling performance, and methods of producing them, where the composite anode materials comprise a core of silicon particles or silicon/graphene hybrid, and a layer of nano-ordered porous carbon coated on its surface. The coated carbon layer was produced by pyrolysis of self-assembled composite of a co-block polymer and a phenolic resin which was prepared from formaldehyde and phenolic compounds with either an acid or base as a catalyst.
