| abstract |
The invention discloses a carbon material having carbon aggregates, wherein the aggregates include carbon nano particles and no seed particles. In various embodiments, the nano-particles include graphene, optionally containing a multi-walled spherical fullerene and / or another carbon allotrope. In different embodiments, the nano particles and aggregates have different combinations of the following: a Raman spectrum with a 2D mode peak and a G mode peak and a 2D / G intensity ratio greater than 0.5; a low concentration Elemental impurities, high Brunauer-Emmett and Teller (BET) surface area, large particle size and / or high electrical conductivity. A method of producing such carbon materials is provided. |
