Abstract
A process for producing graphitic foam comprises mixing a first amount of an activated first carbon precursor with a second amount of a second carbon precursor, heating the mixture of the activated first and the second carbon precursors to a temperature sufficient to coalesce the mixture into a liquid, foaming the mixture, heating the foam under an inert atmosphere to a temperature and for a length of time sufficient to carbonize the foam, and heating the carbonized foam under an inert atmosphere to a temperature and for a length of time sufficient to graphitize the foam.
