Abstract

Electrochemical carbon formation from a graphite anode has been investigated in an LiCl molten salt containing oxygen ions. Carbon can be formed via various chemical or electrochemical routes. The carbon dust produced during electrolysis probably contaminates the salt and it leads to a decrease of the current efficiency and the purity of the metal product. A possible reaction path for carbon formation during electrolysis has been proposed in this study.
