Patent number: 8628707Abstract: A system for making carbon foam anodes including a digestion vessel in communication with a coal feedstock unit for producing a digested coal; a mold having an interior for accepting the digested coal to produce an ungraphitized carbon foam anode having a desired shape; a pressure unit in communication with the mold for producing an increased pressure within the interior of said mold; a heating element in communication with the mold to provide heat to the mold sufficient to convert the digested coal into the ungraphitized carbon foam anode; and a graphitization oven for graphitizing the ungraphitized carbon foam anode to produce the carbon foam anode. The present invention further includes methods for making carbon foam anodes.Type: GrantFiled: January 8, 2008Date of Patent: January 14, 2014Assignee: Carbonxt Group LimitedInventors: Randall J. Harris, Damian Wales
