Abstract

There are two issues in carbon electrodes for fluorine gas production by molten fluoride electrolysis. One is the anode effect and the other is anode breakage. The former arises through the formation of carbon-fluorine compounds on the surface of carbon electrodes. The formation results in a lower affinity between the surface and the electrolyte, which significantly decreases the performance of the electrode for the electrolysis. The latter is also mainly caused by the reaction of carbon and fluorine, i.e. the formation of fluorine intercalation compounds accompanied by a volume increase which induces the breakage of the electrodes. In this article, we discuss the mechanism of the two issues, and show that control of the properties and structure of carbon electrodes are necessary. Based on many references and our findings, it is concluded that the carbon with a lower crystallinity than graphite and a high density shows a higher performance and a higher durability than a conventional carbon electrode.
