Abstract
Graphite sheets having enhanced surface area are prepared from flexible graphite sheets to which an activated carbon precursor has been added, followed by activation of the precursor. The sheets with enhanced surface area are useful in the formation of articles adapted for use in supercapacitors.
Claims9
