Abstract

Graphene-like graphite prepared by heating graphite oxide under vacuum at 800°C was fluorinated by elemental fluorine in the presence of HF at room temperature. The interlayer spacing of the resulting material was 0.639 nm and it showed CxF type characteristics. The fluorine content of it (x = 1.7) was higher than that obtained from natural graphite (x = 2.3). The discharge capacity of it as a cathode of lithium primary battery reached 940 mAh g−1 at a low current density, which was 50% larger than the theoretical capacity based on the 100% discharge of fluorine.
