1. Graphenic carbon particles that are thermally produced by heating a precursor material comprising methane or a hydrocarbon material capable of forming a two-carbon-fragment species in a thermal zone having a temperature of greater than 3,500° C. to form the graphenic carbon particles from the precursor material; said graphenic carbon particles having an aspect ratio of greater than 3:1, a B.E.T. specific surface area of at least 50 square meters per gram, an average of 3 or more carbon atom layers having turbostratic misalignment, and a Raman spectroscopy 2D/G peak ratio of at least 1.1:1.
