Abstract

"Overcharging" of pure stage graphite hydrogenosulfate i.e charging of graphene layers with expulsion of H+ from the intercalate layer is modelized by transmission lines which agree quite well with A.C Impedance measurements. The meaning of the apparent Diffusivity Da = 12 /3 R1C1 is discussed as significant of the displacement of H+/e− holes pairs along the blocking interface separating graphene and intercalate layers.
