摘要：
Surface free energy, electrical conductivity and charge transfer between carbon and fluorine have been obtained for the fluorine-graphite intercalation compound, C(x)F, and the mechanism of anode effect prevention by C(x)F is discussed. It has been found that C(x)F has higher wettability by ionic KF.2HF melt than not only graphite fluoride with a covalent C-F bond but also graphite itself. The electrical conductivity of C(x)F is much higher than that of pristine pyrolytic graphite at stage II or higher. These properties of C(x)F are brought about by electron transfer from carbon to fluorine, and give rise to favorable conditions at the carbon anode whilst carrying out the electrolysis of a KF.2HF melt at a high current density.
