Structurally designed graphene-layers were synthesized by fusing two kinds of poly-aromatic hydro carbons: coronene and pentacene. Na ion battery anode properties were investigated for the obtained amorphous carbons. It was found that both coronene and pentacene based materials had high reversible capacities (ca. 100 mA h g−1). Na ion storage mechanisms for the two carbon samples were investigated by ex situ XRD and NMR measurements.
