Claim 0:
1. A three-dimensional (3D) porous silicon (Si)-comprising and carbon (C)-comprising nanocomposite particle, comprising:
interconnected curved and defect-comprising graphene;
Si or Si-comprising active material in direct contact with the interconnected curved and defect-comprising graphene;
at least one more material distinct from the interconnected curved and defect-comprising graphene and the Si or Si-comprising active material; and
internal pores that at least partially accommodate volume changes in the Si or Si-comprising active material during insertion and extraction of lithium ions, at least some of the internal pores formed by the interconnected curved and defect-comprising graphene,
wherein:
the internal pores comprise one or more micropores; and
the interconnected curved and defect-comprising graphene is characterized by a radius of curvature in a range of about 0.3 nm to about 0.03 mm.
