Abstract
Graphenic carbon particles having controlled aspect ratios, surface areas, numbers of carbon atom layers, and Raman spectroscopy peak ratios are disclosed. The graphenic carbon particles may include three or more stacked carbon atom layers, and may have a Raman spectroscopy 2D/G peak ratio of at least 1:1. Adjacent carbon atom layers within each graphenic carbon particle may be slightly misaligned with respect to each other to form a turbostatic structure.
