Polycyclic aromatic hydrocarbons (PAHs) with a discharge capacity of 1017 mAh/g and efficiency of 81.5% were developed for rechargeable Li-ion batteries using isotropic pitch as the raw material. The PAHs have a very small specific surface area and small micropores. X-ray diffraction results show that PAHs consist of a few graphene sheets stacked in a parallel fashion (L-c = 16 Angstrom) and separated by a small distance (d(002) = 3.46 Angstrom). The results of solid-state C-13-nuclear magnetic resonance suggest that the graphene sheets have a coronene-like structure, namely, they show a disk-like shape. Based on its structural characteristics, we proposed a mechanism for Li-ion storage.
