FIELD: nanoporous materials.
SUBSTANCE: invention relates to carbon-based nanoporous materials, more specifically to carbon aerogels suitable for use in environments in which electrochemical reactions are carried out, for example, as an electrode material in a lithium-ion battery. The carbon composition contains a carbon material and a silicon-based material. The carbon material has a porous structure, and the carbon composition contains more than about 10% by weight of the silicon-based material and has a silicon utilization ratio of at least about 20%. The carbon material has one or more of the following properties: a porous structure having a fibrous morphology, an elastic modulus of at least about 0.2 GPa, an electrical conductivity of at least about 10 S/cm, and a density of at least about 0 .15 g/cm3 to about 1.5 g/cm3.
EFFECT: improved performance.
