Title: Flexible graphite sheet with decreased anisotropy

Abstract: Flexible graphite sheet is made by compressing a mixture of relatively large particles of intercalated, exfoliated, expanded natural graphite with smaller particles of intercalated, exfoliated expanded, expanded particles of natural graphite. The resulting sheet of flexible graphite exhibits increased electrical conductivity through the thickness ("c" direction) of the sheet and improved sealability perpendicular to the "c" direction.
