A. Dependence of the Resistivity on Fluorine Concentration

At low [F] concentrations, the behavior is similar to other acceptor GICs [25]. Initially, the conductivity increases upon fluorine intercalation (see Fig. 12) until a maximum conductivity is achieved, followed by a decrease in cr upon further fluorine intercalation. This behavior is typical of all acceptor GICs and is seen in Fig. 12 to occur for a variety of graphite host materials.
